The vagus nerve is critical to optimal health, no matter what your issues are.

Introduction to The Vagus Nerve

In people with fatigue, food sensitivities, anxiety, gut problems, brain fog, and depersonalization, the vagus nerve is almost always at play. These people have lower vagal tone, which means a lower ability to perform its functions.

The only question is which aspect of the vagus nerve is malfunctioning and to which extent it is the problem vs. other aspects of your biology.

The vagus nerve is part of the parasympathetic nervous system, referred to as the rest-and-digest system. It’s not the only nerve in the parasympathetic system, but it’s by far the most important one because it has the most far-reaching effects.

The word vagus means “wanderer,” because it wanders all over the body to various important organs.

The vagus nerve reaches the brain, gut (intestines, stomach), heart, liver, pancreas, gallbladder, kidney, ureter, spleen, lungs, fertility organs (female), neck (pharynx, larynx, and esophagus), ears, and tongue.

Given the importance of the vagus nerve to the gut (and other organs), when it’s not working properly, it will cause digestive disorders including dyspepsia, gastroparesis, esophageal reflux, ulcerative colitis, anorexia, and bulimia, to name a few (R).

The Vagus Nerve and Health

In the brain, the vagus helps control anxiety and depression.

In the gut, it increases stomach acidity, digestive juice secretion, and gut flow. Since the vagus nerve is important for increasing gut flow (motility), having less vagus activation will increase your IBS risk, which is a result of slower flow (R).

Stimulating the vagus nerve increases the release of histamine by stomach cells, which helps release stomach acid (R). So, low stomach acidity is usually, in part, a vagus nerve problem. By releasing intrinsic factor, the vagus nerve is important to help you absorb vitamin B12 (R).

In the heart, it controls heart rate and blood pressure. Vagus activation will lower the risk of heart disease, among other lethal diseases (R).

In the liver and pancreas, it helps control blood glucose balance (R).

In the gallbladder, it helps release bile, which can help you get rid of toxins and break down fat.

The vagus nerve promotes general kidney function. It helps with glucose control. The vagus nerve also increases blood flow (R), which improves blood filtration. Vagus activation also releases dopamine in the kidneys, which helps excrete sodium (R) and, thereby, lower blood pressure.

The vagus nerve goes to the bladder (R). A side effect of its stimulation is urinary retention (R), which means that less vagus stimulation can cause you to urinate frequently. Indeed, many of my clients complain about frequent urination (also due to low vasopressin, low aldosterone, and high cortisol).

In the spleen, it can reduce inflammation (R). Note that vagus activation will reduce inflammation in all target organs (by releasing acetylcholine) (R), but when it activates in the spleen the response will probably be more systemic.

It helps control fertility and orgasms in women by connecting to the cervix, uterus, and vagina. Women can actually experience orgasms simply from the vagus nerve (R).

In the tongue, it helps control taste and saliva; while in the eyes, it helps release tears (R).

A friend asked me what’s the connection between having to go to the bathroom and congestion. It’s likely the vagus nerve because it controls both mucous production and colon flow.

Satiety and relaxation following a meal are in part caused by activation of the vagus nerve transmission to the brain in response to food intake (R).

The vagus nerve explains why a person may cough when tickled on the ear, such as when trying to remove ear wax with a cotton swab (R).

Vagus nerve stimulation helps people with tinnitus because of its connection to the ear.

The vagus nerve is important in conditions like GERD, not only because it controls stomach acidity, but also because it controls the esophagus.

The vagus nerve is largely responsible for the mind-body connection since it goes to all the major organs (except adrenal and thyroid glands).

It’s intimately tied to how we connect with one another — it links directly to nerves that tune our ears to human speech, coordinate eye contact, and regulate emotional expressions. It influences the release of oxytocin, a hormone that is important in social bonding (R).

Studies have found that higher vagal tone is associated with greater closeness to others and more altruistic behavior (R).

Vagus activity of a child can be affected by their mother. Infants had lower vagus activity with mothers who were depressed, angry, or anxious during pregnancy (R).

Som studies suggested that the vagus nerve is important for getting in the mental state of flow. It’s believed that the combination of sympathetic (fight-or-flight) and vagus activation creates the right environment for a flow state (R).

The Vagus Nerve and Sickness Behavior

Sickness behavior (fatigue, sleepiness, depression, anxiety, appetite loss, pain, lowered motivation, and failure to concentrate) is blocked when the vagus nerve is taken out. IL-1b mediates the activation of this nerve causing sickness behavior (R).

Genetics/Testing For Vagus Activity

SelfDecode, the best genetic analyzer for 23andme and ancestry data, analyzes some SNPs that modulate vagal activity.

One such SNP (rs6330) is associated with low vagal activity and increased anxiety. You must have your genome sequenced (preferably by 23andme) and sign up to see if you have this variation of the gene.

Potential Symptoms of Vagus Nerve Dysfunction

  • Obesity and Weight Gain (R)
  • Brain problems
  • IBS
  • Depression
  • Anxiety
  • Chronic Fatigue
  • High or Low Heart Rate
  • Difficulty Swallowing
  • Gasteroparesis, also known as delayed gastric emptying,
  • Heart Burn
  • Dizziness/Fainting
  • B12 Deficiency
  • Chronic Inflammation

Conditions Which Vagal Nerve Activation Can Help

Since the vagus nerve is associated with many different functions and brain regions, research shows positive effects of vagal stimulation on a variety of conditions, including but not limited to (R):

The Vagus Nerve and Hormones

Vagus Nerve Stimulation normalizes an elevated HPA axis (CRH, ACTH, and cortisol) (R).

The vagus nerve can help reduce pain, and this is the mechanism by which estradiol reduces pain in certain circumstances (R).

Insulin activates the vagus nerve through a domino of steps leading to decreased glucose production by the liver (R).

In rats, the thyroid hormone (T3) increases appetite by activation of the vagus nerve, which also increases ghrelin (R).

Ghrelin increases hunger by stimulating the vagus nerve signal from the brain to the gut, and this is abolished by capsaicin (in chili) (R).

Besides influencing the release of oxytocin (R), the vagus nerve is important for releasing testosterone. If it’s not working well, it could be the cause of low testosterone (R).

Testosterone can make people more aggressive, but this is not the case when the vagus nerve is functioning right (R).

Proper functioning of the vagus nerve is important for the production of GHRH (growth hormone releasing hormone) and IGF-1 (R).

The vagus nerve can stimulate other hormones such as parathyroid hormone (R), which is important for the conversion of vitamin D3 to active vitamin D (1,25).

Stimulation of the vagus nerve produces the release of the vasoactive intestinal peptide (VIP(R), which is often low in people with CIRS/mold conditions.

NPY blocks some of the vagus nerve effects. NPY, is an anti-anxiety and hunger increasing hormone, which prevents heart rate decrease from vagal stimulation (R).

Acetylcholine

Acetylcholine is the main vagal neurotransmitter. This means that it will have many of the effects of vagal stimulation because this is how the vagus nerve stimulates various organs.

Acetylcholine significantly decreases the release of cytokines such as TNF, IL-1b, IL-6, and IL-18 in LPS-stimulated human immune cultures (R).

Alpha GPC is the best way to increase acetylcholine. However, I don’t know if it will get to where it needs to go and in the proper dosage, so I doubt it’s as good as vagus stimulation.

32 Ways to Stimulate The Vagus Nerve

1) Cold

coldshower_245687524

Studies show that when your body adjusts to cold, your fight-or-flight (sympathetic) system declines and your rest-and-digest (parasympathetic) system increases, which is mediated by the vagus nerve (R).

Any kind of acute cold exposure will increase vagus nerve activation (R).

You can dip your face in cold water to start (R).

I graduated and now take fully cold showers, expose myself to cold, and drink cold water.

2) Singing or Chanting

shutterstock_220097938

Singing increases Heart Rate Variability (HRV) (R).

Humming, mantra chanting, hymn singing, and upbeat energetic singing all increase HRV in slightly different ways (R).

I do Om chanting in my infrared sauna (R).

Singing initiates the work of a vagal pump, sending relaxing waves through the choir (R).

Singing at the top of your lungs works the muscles in the back of the throat to activate the vagus.

Energetic singing activates your sympathetic nervous system and vagus nerve and conducts towards getting in a flow state (R).

Singing in unison, which is often done in churches and synagogues, also increases HRV and vagus function (R).

Singing has been found to increase oxytocin (R).

3) Yoga

shutterstock_207304351

Yoga increases vagus nerve activity and parasympathetic system in general (R,R2).

A 12-week yoga intervention was associated with greater improvements in mood and anxiety than a control group who did walking exercises. The study found increased thalamic GABA levels, which were associated with improved mood and decreased anxiety (R).

4) Meditation

shutterstock_336730823

There are two types of meditation that can stimulate the vagus nerve.

Loving-kindness meditation increases vagal tone, as measured by heart rate variability (R).

Also, Om chanting stimulates the vagus nerve (RR2).

5) Positive Social Relationships

shutterstock_326785574

In a study, participants were instructed to sit and think compassionately about others by silently repeating phrases like “May you feel safe, may you feel happy, may you feel healthy, may you live with ease,” and keep returning to these thoughts when their minds wandered (R).

Compared to the controls, the meditators showed an overall increase in positive emotions, like joy, interest, amusement, serenity, and hope after the class. These emotional and psychological changes were correlated with a greater sense of connectedness to others and to an improvement in vagal function, as seen by heart-rate variability (R).

Simply meditating, however, didn’t always result in a more toned vagus nerve. The change only occurred in meditators who became happier and felt more socially connected. Those who meditated just as much but didn’t report feeling any closer to others showed no change in the tone of the vagus nerve (R).

6) Breath Deeply and Slowly

Deep and slow breathing stimulates the vagus nerve (R).

Your heart and neck contain neurons that have receptors called “baroreceptors.”

These specialized neurons detect your blood pressure and transmit the neuronal signal to your brain (NTS), which goes on to activate your vagus nerve that connects to your heart to lower blood pressure and heart rate. The result is a lower fight-or-flight activation (sympathetic) and more rest-and-digest (parasympathetic).

The baroreceptors can be more or less sensitive. The more sensitive they are, the more likely they are going to fire and tell your brain that the blood pressure is too high and it’s time to activate the vagus nerve to lower it.

Slow breathing, with a roughly equal amount of time breathing in and out, increases the sensitivity of baroreceptors and vagal activation, which lowers blood pressure and reduces anxiety by reducing your sympathetic nervous system and increasing your parasympathetic system (R).

For an average adult, breathing around 5-6 breaths per minute can be very helpful (R).

Tip: You need to breathe from your belly and slowly. That means when you breathe in, your belly should expand or go out. When you breathe out your belly should cave in. The more your belly expands and the more it caves in, the deeper you’re breathing.

7) Laughter

As the saying goes, laughter is the best medicine. Many studies show the health benefits of laughing (R).

It seems like laughter is capable of stimulating the vagus nerve.

A study done on yoga laughter found increased HRV in the laughter group (R).

There are various case reports of people fainting from laughter, which may be from the vagus nerve/parasympathetic system being stimulated too much.

For example, fainting can come after laughter, urination, coughing, swallowing or bowel movement, all of which are helped along by vagus activation (R).

There are case reports of people passing out from laughter who have a rare syndrome (Angelman’s) that’s associated with increased vagus stimulation (R, R2).

Laughter is also sometimes a side effect of vagus nerve stimulation (R).

Laughter is also good for cognitive function (R) and protects against heart disease (R).

Laughter increases beta-endorphins and nitric oxide and benefits the vascular system (RR2).

8) Prayer

shutterstock_301871300

Studies have shown that reciting the rosary prayer increases vagus activation. Specifically, it enhances cardiovascular rhythms such as diastolic blood pressure and HRV (R).

Studies also found that the reading of one cycle of the rosary takes approximately 10 seconds and thus causes readers to breathe at 10-second intervals (includes both in and out breath), which increases HRV and therefore vagus function (R).

9) PEMF

Magnetic fields are capable of stimulating the vagus nerve (R).

Studies have found that PEMF can increase heart rate variability and increase vagus stimulation (R).

I use a pulsed magnetic stimulator called ICES on my gut and brain, which stimulates my vagus nerve increasing my appetite and stimulating me.

I recommend using this on your gut, brain, and side of your neck.

My gut flow increases and inflammation is reduced everywhere when I put this on my gut.

At first, I didn’t understand how it can have systemic effects if I placed it on my gut, but the vagus nerve must be the main reason given that it’s stimulated by magnets.

10) Breathing Exercises

Breathing in and out with resistance will likely stimulate your vagus nerve better –kind of like jogging with a backpack.

A breathing exercise is to breathe out as hard as you can until it’s really uncomfortable and until you notice how awake you are. I haven’t seen studies on this, but I suspect it will help with your vagus nerve.

11) Probiotics

The gut nervous system connects to the brain through the vagus nerve. There is increasing evidence pointing to an effect of the gut microbiota on the brain.

Animals supplemented with the probiotic Lactobacillus rhamnosus experienced various positive changes in GABA receptors mediated by the vagus nerve (R).

12) Exercise

shutterstock_364331810

Mild exercise stimulates gut flow. This is mediated by the vagus nerve, which means that exercise also stimulates it (R).

13) Massages

Massaging certain areas like your carotid sinus (located on your neck) can stimulate the vagus nerve. This helps reduce seizures (R).

A pressure massage can activate the vagus nerve. These massages help infants gain weight by stimulating gut function and this is largely mediated by vagus nerve activation (R, R2).

Foot massages can also increase vagal activity and heart rate variability, while lower your heart rate and blood pressure (R). All of these decrease heart disease risk.

14) Fasting

Intermittent fasting or reducing calories both increase high-frequency heart rate variability in animals (R), which is a marker of vagal tone.

Indeed, many anecdotal reports show that intermittent fasting benefits heart rate variability.

When you fast, part of the decrease in metabolism is mediated by the vagus nerve.

Specifically, the vagus detects a decline in blood glucose and a decrease of mechanical and chemical stimuli from the gut. This increases the vagus impulses from the liver to the brain (NTS), which slows the metabolic rate (R).

Hormones such as NPY increase while CCK and CRH decrease during fasting (R).

When we eat, the opposite happens. Satiety-related stimulatory signals from the gut contribute to increased sympathetic activity and stress-responsiveness (higher CRHCCK, and lower NPY) (R).

Fasting can increase the activity in the subdiaphragmatic vagus, which can increase an unfavorable sensitivity to pain in animals (R).

The vagus nerve may make you more sensitive to estrogen. In female rats, fasting increases the number of estrogen receptors in certain parts of the brain (NTS and PVN) by the vagus nerve (R).

15) Sleep or Lay on Your Right Side

Studies have found that laying on your right side increases heart rate variability and vagal activation more than being on other sides. Laying on your back leads to the lowest vagus activation (R).

16) Tai Chi

Tai chi increases heart rate variability and, therefore, very likely vagus activation (R).

17) Gargling

The vagus nerve activates the muscles in the back of the throat that allow you to gargle.

Gargling contracts these muscles, which activates the vagus nerve and stimulates the gastrointestinal tract.

Before you swallow water, gargle it first.

18) Seafood (EPA and DHA)

I’m a big proponent of fish in the lectin avoidance diet.

EPA and DHA increase heart rate variability and lower heart rate (R). This indicates that they stimulate the vagus nerve.

I’ve taken ten pills of fish oil as a megadosing experiment and my heart rate went from 60 to 40. So, in my self-experiments, fish oil does indeed lower heart rate, which is probably mediated, in part, by the vagus nerve.

19) Oxytocin

Oxytocin increases vagal nerve activity from the brain to the gut (in the brain and orally ingested) (R), which induces relaxation and decreases appetite.

Mice who had their vagus taken out didn’t have the appetite-reducing effects of oxytocin (R).

20) Zinc

Zinc increases vagus stimulation in rats fed a zinc-deficient diet for 3 days (R). It’s a very common mineral that most people don’t get enough of.

21) Tongue Depressors 

Tongue depressors stimulate the gag reflex.

Some say that gag reflexes are like doing push-ups for the vagus while gargling and singing loudly are like doing sprints.

22) Acupuncture

Traditional acupuncture points stimulate the vagus nerve (R).

In particular, acupuncture to the ear stimulates the vagus nerve (R).

Acupuncture is powerful enough that a man died after vagus nerve stimulation from too low of a heart rate (R).

23) 5-HTP (Serotonin)

Serotonin is capable of activating the vagus nerve through various receptors.

The effects are mediated in part by the activation of 5HT1A (R), 5-HT2 (R), 5-HT3 (R), 5-HT4 (R), and perhaps 5-HT6 (R) receptors.

On the other hand, 5-HT7 receptors reduce vagus activation (R, R2).

So, serotonin has some mixed effects, but overall it should stimulate the vagus nerve.

You can take 5-htp to increase serotonin.

24) Chew Gum (CCK)

CCK directly activates vagal impulses to the brain (R).

CCK ability to reduce food intake and appetite is dependent on the vagus nerve impulse to and from the brain (R).

Chewing gum helps increase CCK release.

25) Eat Fiber (GLP-1)

GLP-1 is a satiating hormone that stimulates vagus impulses to the brain, which acts to slow the emptying of your stomach and make you feel fuller (R). It also works by increasing CRH (R).

Fiber is the best way to increase GLP-1.

26) Coffee Enemas

Enemas are like sprints for your vagus nerve. Expanding the bowel increases vagus nerve activation, as is done with enemas.

27) Coughing or Tensing the Stomach Muscles

When you bear down as if to make a bowel movement, you stimulate your vagus nerve. That’s why you might feel relaxed after a bowel movement.

So if you use these bowel movement muscles, it will stimulate your vagus nerve (R).

28) Thyroid Hormones/T3 Are Normal

In rats, the thyroid hormones (T3) increase appetite through activating the vagus nerve, which also increases ghrelin (R).

29) Sun (MSH)

Alpha-MSH activates the vagus nerve. It is capable of preventing damage from a stroke via activating the vagus nerve, which suppresses inflammation (R, R2).

Alpha-MSH injection in the brain (DMV) moderately excites the vagus nerve in some conditions (R).

30) Carbohydrates (insulin)

Insulin activates the vagus nerve in some ways through intermediaries (R).

31) Orexin

Orexin neurons are found in centers which control vagus nerve activation from the brain (NTS, DMV, and the area postrema) (R).

Orexin stimulates the vagus nerve from the brain, which promotes gut flow (R).

Orexin A can stimulate the pancreas from the brain (R).

Orexin is capable of increasing glucose tolerance or insulin sensitivity via the liver vagus nerve (R).

On the other hand, orexin is capable of inhibiting the activation of the vagus nerve signals to the brain by competing with CCK (R).

32) Ghrelin

Ghrelin increases growth hormone and hunger by stimulating the vagus nerve signal from the brain to the gut, and this is abolished by capsaicin (in chili) (R).

Ghrelin stimulates the pancreas from the brain via the vagus (R).

Others

Leptin

Vagal impulses to the brain are activated by leptin. Leptin potentiates the CCK-induced activation of the vagus nerve (R).

Animals bred to be leptin resistant were hungrier since the vagus nerve became less sensitive to CCK (R).

However, another study found that leptin effect on the vagus signal to the brain doesn’t play a major role in food intake (R).

CRH

CRH has variable effects on the vagus nerve. It decreases its activity from the brain to the heart. Vagus nerve activation will slow the heart rate, but CRH inhibits this and increases heart rate (R).

CRH stimulates the vagus impulse from the brain (area postrema) to the colon (by activating the dorsal nucleus of vagi, via cholinergic transmission) (R).

MSG

Monosodium Glutamate or MSG increases gut flow in dogs, which is mediated by the vagus nerve (R).

How Does The Vagus Nerve Malfunction?

So your vagus nerve system can be messed up in 3 main ways: Communication from an organ to the brain (via glutamate), communication within the brain (such as from the NTS or to the DMV), or communication from the brain to other areas of the body like the heart, liver, and gut (R).

The Vagus Nerve and the Circadian Rhythm

Signals from the circadian control center (SCN) are often transmitted by the vagus nerve.

For example, mucin production by your gut and lungs has a rhythm that’s controlled from your SCN (R).

If your circadian rhythm is broken, your vagus nerve will be broken to some degree. See how to take care of your circadian rhythm.

How to Inhibit the Vagus Nerve

Capsaicin is the most potent way to inhibit the vagus nerve.

Ginger prevents nausea and vomiting by inhibiting the vagus nerve serotonin function in the digestive tract (R, R2).

Vagus Nerve Terms

You can stimulate or inhibit the vagus nerve in two ways. First, the vagus nerve impulse (activation) can flow from the brain to the rest of the body or from the body to the brain.

When it flows from the brain it’s called a “vagal efferent.” When it flows from other parts of the body to the brain, it’s called a “vagal afferent.” I don’t use these terms for simplicity.

The high-frequency heart rate variability (HRV) is associated with vagus nerve/parasympathetic activity (R, R2).

The low-frequency HRV is associated with both sympathetic and parasympathetic activation (R, R2).

    Not sure in fasting why you say CCK is a stress hormone, so beneficial when it’s not released whilst you fast, then you say in chewing gum that it’s beneficial that CCK is released. Whilst both statements are true about the physiological response to CCK, your view on it is opposing.

  • An-Marie

    Great article. I would like to follow further comments.

  • Dan D.

    Hi! This is definitely an interesting article! My question is: I have recently had a hiatal hernia repair with a Reese twist procedure. (Hope the spelling is correct as I am a novice on my body function, especially this Vegas Nerve.) I have experienced problems ever since I tried t go back on normal food (vs. soft foods). I have been in the emergency room hospital 3 times in the last 2 weeks because of diarrhea & also abdominal pain if I control the diarrhea with various medicine. It has been almost 2 MONTHS since my surgery and I did NOt have these symptoms before the Surgery. In the last visit I was told my problems involve the Vegas Nerve being damaged. The Doctor says he thinks the situation will correct over time as the Vegas Nerve returns to normal. Does this diagnose sound reasonable. Does this happen very much to people that have Hiatal Hernia Surgery. I would really appreciate your response.
    Sincerely

  • Mark

    Im interested in the answers to this. I had an ablation done and the vagus nerve was burned on purpose.

  • Pat

    Can you tell me why the codes rs6330 are not on my 23 and me? Are you using other codes? And can you tell me if a vagus nerve is also damaged from spinal nerve damage (mid L-T). And if there is any help for this problem to pursue?

  • anony

    Vomiting also rises blood pressure and may have adverse effects. it can be dangerous for some people.

  • Nejc

    Yes it does. Beside general infectiona there are no commercialy available that are targeted. Probably with a biopsy.

  • Gustavo Fernando Lourenço

    Does the theory of the virus-infected or bacteria-infected vagus nerve have any foundation? If yes, which exam could detect this type of problem and which treatment could be applied?

  • Carla Havard

    I have epilepsy and I have a Vagus Nerve Stimulator to prevent seizures. Every 2.8 minutes the stimulator sends an electric impulse to my brain through the Vagus nerve. I am wondering since I get automatic stimulation, how will this affect my body.

    Hey there is a company with a new product which is like a pacemaker for the vagus nerve. Surgically implanted 2 wires and a small subcutaneous controller. FDA approved for obesity and elevated cholesterol at moment. BTW, vagus Stim increases adiponectin. Why it works for obesity, it increases insulin sensitivity that way.

  • hello

    i was diagnosed with a weak vagus nerve last 2013. what came with it was bradycardia (all though i stopped at sports for quite a while), arrhythmia, depression, ringing in the ears, hypersensitivities to food (my skin flares up when i eat unknown stuff even those things i normally eat), gastritis, and snowstorm faintings. while the other doctors were cracking their heads identifying what’s wrong with me, it was my neuro who nailed it. she was kind to me and explained all what i have been experiencing. she referred me to a new cardiologist who now monitors my heart.

    in all my stress test, it was discovered by the cardio that my heart stabilises when i run. it means i didn’t have arrhythmia and my heart is on a normal pace. he then suggested i start running.

    cut to now, i am on a whole foods plant-based diet. no more allergies, i can sleep 8 hours a day, less ears ringing and fainting. and now, i am about to run my first 100k trail run!

    Hi adrea I have the same symtoms and I’m not doing well an

  • Colleeen

    i’m so sorry to hear of your distress. I’m not a scientific person either, but “vagus nerve” kept coming up and I decided to look into it. Recently I started doing deep breathing exercizes and it’s kind of amazing. Breathe in and out slowly but with the aim of filling up (inbreath) and actually pushing out your stomach muscles to the point you feel like you are bearing down and your pants are getting really tight. And the outbreath pull your stomach muscles and anus in as well (root lock in yoga). Eazy peazy and can do it while driving!!
    Good luck and may you and all beings everywhere be peaceful happy and free

  • Ramesh Gupta

    I am trying to keep my Valgus nerve stimulated as much as possible and I feel better, more relaxed and happier!

  • Andrea

    Hi Emily and everyone, can I ask what triggers the blood pressure to drop to your husband? I suffer from vaso vagal syncope too (and also HB A+A2 Alpha Thalassemia trait). In most cases I suffer too often from stomachaches and they are triggered when I am still digesting and there is a draft of wind, particularly if I am sweat, even if outside there are 28 degrees or if I am eating for example complex food in the morning, not well cooked like a pizza, or if the food even if fresh is 3 days old. This lead after few or even several hours to acidity or having an upset stomach which can last even 18 hours, even when cured with digestives and I can feel light headed, dizzy, difficulty to focus and answer even simple question, prolonged burping, heavy stomach. It can get worse when I experience numbness on my face, cold hands, and I barely answer to question as I feel low pressure as the blood goes away from my brain (this is close to fainting). If the difference of temperature between my body and the external environment is big this can escalate to food congestion which if not cured/noticed in time can lead to fainting first and puking after (this also happens with viruses to my stomach). If taken in time I could spend 5 hours lying down before feeling better and able to stand up. My digestive time seems longer than usual between 4-6 hours (without counting 30 min to start digestion), my diet is composed mainly of fresh food.

    As you can imagine is affecting my social life and draining my energy, when I go out I got used to bring with me a shell jacket and a wind jacket even if it is really warm, this is palliative measure as it just increases my body heat, it does however protect me from external agents. After finding this topic I am determined to go at the bottom of this despite all doctors said there is not cure and get better when I get older.

  • bob

    Huperzine doesnt interfere with Acetylcholine, but with Acetylcholinerase. Big difference there.

  • Nicole

    Hi Mark, curious what your doctor said about the connection with the ablation and the new symptoms you are having. I’m scheduled to have an ablation for benign PVCs in 2 months and I’ve seen very mixed reviews of the after effects. Hopeful you are getting better by now.

  • Oriononthehorizon

    Great article! I didn’t see huperzine a mentioned. It is from the plant Huperzia Serrata. Huperzine inhibits acetylcholine, the main neurotransmitter the vagus nerve operates with. This makes acetylcholine work better. Anyone trying huperzine a should exercise extreme caution however, and never take more than the recommended dosage. Taking more than the recommended dosage can cause very uncomfortable symptoms, such as muscle paralysis.

  • Loola

    Hi, thanks for this article! I am very confused though. Should it be stimulated if it can cause such problems? For example, me, after having a bowel movement, I feel like passing out. I feel tired, headaches, literally drained. So what does that mean? What should I do, stimulate it? I’m lost, someone please explain..

  • Kez

    This is so interesting. I lost all feelings of hunger (not appetite as so many people confuse it with) over 17 years ago. I was going through a stressful time in my life and it seemed to disappear overnight. I’ve only felt the hunger a few times since, lasting less than 5 seconds. At the same time I also lost general feelings of joy over things I used feel very excited or joyful about such things as an upcoming holiday, being given a present, seeing a beautiful flower or sunset etc. After counselling, acupuncture and homeopathy not making any difference, I’d given up on ever having it resolved, but a couple of months ago I came across a different article about the vagus nerve, I’d never heard of it before. Not being a very scientific person I do find it all very confusing, but this article has really sparked my interest, as on the rare occasions I’ve felt joy it has sometimes been whilst being in a cold lake or the cold sea. If anyone could point me in a more specific direction to help resolve my issues I’d be ever so grateful as I’d love to feel fully alive again.

      Hello Kez…your story touched my heart and I wanted to say a few words. I have just recently learned more in depth about the vagus nerve and the importance of vagal tone. I am subscribed to many wonder news letters from various nutritionists, doctors and health enthusiasts. One of the news letters I recently received has information about the nerve, its’ functions and essential oils that can be used to tone it. She is selling the oil blend through her company and I haven’t tried it yet but I will be ordering it next week (I’m not affiliated with her, her company/products or a paid spokesperson), just someone who has been learning a lot about the medicinal benefits of essentials oils to human health and firmly believe that this will work. This particular article deals with the vagus nerve and digestion. Coupling it with all the info in this article, we can see how extremely important it is for this nerve to function at an optimum level. I hope this helps and leads you to a new path of health and happiness. Many blessings!

      1. Tanya

        What were the oils and methods to use.

      I think you can go to a doctor for vagus nerve stimulation

  • A Zimmerman

    Information: Stephen Porges , Polyvagal Theory. Somatic Experiencing might help with some cases.

  • Laura

    Why do some students occasionally experience nausea in Yoga class? I’ve heard it’s related to the vagus nerve. Thanks.

  • Robin

    Would the above suggestions help reduce vagus nerve inflammation from porphyria or autoimmune antibodies? Can it heal?

      well you have to deal w the inflammation first.

    Hi I am buying a tens digital device , I need to buy new electrodes that are better for the ear, as it comes with pads , does anyone know the correct frequency and Herz range I put in the machine for vagal nerve stimulus through the inner ear in two places with gel, are their other areas I can stimulate? My aim is to help with relaxation, depression anxiety,I thought it may have been 250 hz not sure new to tens treatment just about to order a device , I never responded to meds

    Can a chiropractor Damage the Vagus Nerve? as after having a Neck Adjustment have been feeling sick and having a headache type feeling? Sickness feeling is getting worse?

    Can this be a pinched Nerve?

    If so will this likely go away on its own?

    Or would you reccomemnd another adjustment to try and fix the issue?

    1. Nattha Wannissorn

      I’ve had some injuries from adjustments (or maybe because I didn’t take it easy afterwards). Ask the doctor so they can do an assessment and see what’s going on. It’s also possible that it will go away on its own.

      1. Dan

        If the Nerve is inflamed or irritated will this calm down. My chiro mentioned something about the Vagus Nerve being inflamed and will settle down.

  • Rebekah Durham

    Wonderful information and well written. Thank you.

  • Cherylin

    Thank you for this detailed article. In the 80s, a brilliant chiropractor/ND figured out the most likely cause for Vagus Nerve dysfunction. His name is Theodore Baroody. I highly recommend his book and/or a book by Steven Rochlitz who expanded on Baroody’s work. Here’s an excellent article by Rochlitz –

      Great link, Thank You

  • Bluebirdy

    I enjoyed all of your research and this article, but I fear that others whom I send to this site will stop reading, thinking you don’t know what you are talking about, as soon as they read “Sickness behavior (fatigue, sleepiness, depression, anxiety, loss of appetite, pain, lowered motivation, and failure to concentrate) is blocked when the vagus nerve is taken out. ”
    The vagus nerve is wrapped around every organ of the body. There is no way to remove it. I also appreciate the comments of others who warned not to do this or that, and the reasons.

    1. Nattha Wannissorn

      Hi Bluebirdy,
      Those studies are done in rats or mice, with terms simplified to make sure people understand. We are not suggesting people remove their vagal nerves.

    2. deejayvj

      Pretty sure that refers to cutting the vagal nerve

  • Karl

    Im a bit confused when I eat I get brain effect.what do I do. Activate or relax the vagus nerve also experience some dizzy feeling n brain fog n blurring eyes.also a continuous ringing ears .what do I do.plz tell me

    1. Jen

      I’ve had the symptoms you mention along with several others related to this nerve. I have recently been reading a book called Medial Medium by Anthony William and he addresses all of that. He claims it’s a virus attacking the nervous symptom. It’s on page 50. I’ve been doing the detox and taking supplements to kill the virus and have started to feel much better. I’ve suffered for 30+ years and am now seeing some improvements after only one month.

      1. Marion

        I also read Medical Medium and follow his lifestyle suggestions. Have never felt better.

      2. Veronique

        Hello Jen, Reading your post resonates with me. I have been suffering for almost 30 years and looking for answers. Not sure it is the same as you but can you tell me more? Just the hope that there can be a way out of the suffering is helpful
        In any case I am getting the book

        1. Jennifer

          Anthony William has two books out and one available for pre order. I would highly recommend getting both books. I have been sharing this info with everyone I know because it’s been so beneficial for me. For those of my friends and family who have joined me on this journey; they too have seen amazing results. The bottom line is a change in lifestyle. We feed our bodies with the nutrients they need to heal. It can take a year or even 18 months for those who have been severely compromised but the self discipline is always worth the reward in the end! You can’t put a price on excellent health!

  • Bill

    Joe, can you PLEASE post a warning in your article above to be extremely careful massaging the carotid sinus on both sides! It can cause major reactions in some people (especially older people) and can dislodge plaques to cause strokes if they are present. Also can cause sudden death/heart failure etc.:

    https://en.wikipedia.org/wiki/Carotid_sinus

    (scroll down to ‘Carotid sinus reflex death’). I don’t think it happens in everyone, but it is risky to find out. Especially don’t massage on both sides at the same time as it it signals blood pressure changes to the brain. I quite often feel pulse on neck when I’m anxious and didn’t realise I might actually be causing more problems!

    1. Jan Fleenor-Short

      It is dangerous. It can severely lower the heart rate.

  • Rees

    So very grateful for this exhaustive piece. Indeed, everything we need to know. Thank you!

  • Valeria

    Joe do you treat vagus nerve caused by small intestinal bacterial overgrowth, do you also help with small intestinal bacterial overgrowth,gastroparesis?

    1. Kelly

      I would also like to know this as I have gastroparesis and SIBO.

  • Jon Nixon

    Vomiting is a strong stimulator of vagal tone. There is at least one theory suggesting that anorexics who perform self- emesis are doing so for that purpose. Interesting idea…..

    1. Marcy

      I’ve also heard migraine sufferers get relief from vomiting. I wonder if this is due to vagus nerve stimulation.

  • usatrooper77

    Thanks for the info, just wondering where you got your info, so hard to find it online. I had gastroparesis for quite awhile, but I am recovering. Hopefully some of this will help me keep going in the right direction.

      There are references by every statement. “(R)”

    2. linda

      What did you do to heal your gastroperisis? I’m just recently diagnosed.

  • brian

    Viscum album (Mistletoe) and Dgitalis purpurea (Foxglove – in sub-clinical doses) stimulate the vagus nerve

    1. Jon Nixon

      Foxglove can be a DEADLY cardiac poison- (it is the source of digitalis alkaloids)-if you don’t know EXACTLY what you are doing best NOT to self- experiment with this one- a single leaf can kill a child. Concentration of the theraputic alkaloids varies dramatically depending on where and how the plant was grown, which was why the main ingredient (digitalis) was modified to a more stable and predicably absorbed compound called digoxin, which is still in use, but has largely been replaced by more effective ( and predicable) medications. Every medical student is still required to be able to identify the particular EKG pattern associated with digoxin TOXICITY…….

  • Linda

    Is it possible that there’s a connection between benign non-positional vertigo and Afib because of the Vagus nerve?

  • Amanda Gray

    What about different herbs that stimulate the Vagus nerve?

    1. Daniel Lappin

      From my experience, Bitter herbs trigger the vegus. Try Flora Swedish Bitters.
      Also, from my experience, essential oils trigger the vegus. inhaling and topical applications have a mild effect. Oral ingestion of the essential oils is a powerful treatment. only a few drops, don’t swallow, absorb in mouth, then spit out. Try Basil, rosemary, thyme, cardamon.
      yet you need to consult an aromatherapy practitioner for safety reasons. Search ‘ingestion of essential oils. Some people state risk of ingestion. I found it to be quickly beneficial.

  • Ron

    Great article. Thank you

  • Luke Daniel Borel

    Massage, Rolfing, accupressure, reminds me of thinking about my golf swing. I tend to focus on what I am thinking about and comparing my swing to someone else’s swing. I find that working backwards from the end and working forward from the beginning and then it is like two trains meeting head on in the middle and creating a beautiful wreck. So you can start with a current condition and work backwards, and then work from the result you want and work backwards, and then the two lines of thought meet in the middle at a solution.

  • christine heilman

    Thank you for all your information I will try to implement these in my life I’m in the recovery mode after a total hip replacement I taught physiology and anatomy and massage therapy . My practice included many different holistic modalities , I feel I need to get back to help myself and others. I am very inspired again pain can sure hold you back but no more.

  • Emily

    I’m kind of confused by a lot of this information. I have some of the conditions listed, and my vagus nerve definitely isn’t working correctly. (Dysautonomia/POTS along with a long list of me/cfs, ibs, endo, low testosterone+cortisol, bradycardia, hypotension, seizures, etc.) Please tell me if I’m not understanding this page correctly, but my interpretation is that stimulating the vagus nerve will help it to function better and improve symptoms.

    However, some of the effects you list from stimulating the vagus nerve are–while frequently described as ‘positive’ effects–would be deadly for me….such as lowering blood pressure (singing, breathing), lowering resting heart rate (fish oil & acupuncture especially, breathing, massages), increased likelihood/rates of passing out (laughter), and lowering cortisol levels (laughing). Should I instead, then, explicitly avoid things that would stimulate my vagus nerve and work to somehow de-activate it?

    I had thought that the vagus nerve was involved in ‘regulating’, rather than explicitly ‘lowering’.

    Are you confusing, as is often the infuriating case in America, that ‘less’ of anything is always better, and that rather than say that doing X will stabilize levels of Y… instead claim that doing X will lower levels of Y because levels of Y in America are frequently too high? (‘Y’ in America frequently being cholestrol, blood pressure, weight.)

    If so, I’d be happy to know that I can safely go about stimulating my vagus nerve and that it could potentially improve my symptoms. However, please keep in mind that hypotension, bradycardia, hypocortisolemia are all serious problems and that ‘stabilizing’ is a more accurate and responsible description. If not, I will avoid and try to stop doing many of the things on this list.

    1. Joseph M. Cohen

      Lowers, doesn’t stabilize

    2. Luke Daniel Borel

      I find abdominal and stomach and solar plexus and Vega nerve massage to be the most important self massage that I can do. I also massage my kidneys and liver. Doing this self massage on all of the above makes me feel like a Happy Bhudda I do this self massage to myself for about one hour a day, every other day.

      1. Ellen

        Can you elaborate on the correct procedure to massage the Vagas nerve? I’ve had several episodes the past year that lead me to believe mine may be out of whack. Id love to try this method before going to a traditional doctor.

    3. lillian

      Wonderful article. I am not sure what my husband should be doing as he was diagnosed with vasovagal syncope which used to be triggered by needles or seeing surgical procedures. He hasn’t experienced an episode in 10 years (weirdly enough he was overweight) but recently lost weight through diet and exercise and has had a few fainting episodes. He also has trouble sleeping and other issues that are mentioned. I suspect his Vegas nerve isn’t working properly but this leaves me to wonder should he be stimulating the Vegas nerve? Would this help his fainting episodes and sleeping issues. Oddly he already does alot of things mentioned before we even knew about it. (Cold showers, breaking out in song)

    4. Decagrog

      I strongly suggest to avoid stimulation of the vagus nerve, specially if you already suffer from and overactive parasympathetic system.
      You risk to go in deep bradycardia and have a vasovagal syncope if not worse.
      This suggestion is valid for everyone, overstimulating the vagus nerve is not a child play, you are putting your finger to a delicate balance that control your cardiac muscle.

  • Rashida

    I am facing several issues which I suspect aee vagal related. I get these sudden episodes ,generally after I wake up from deep sleep, where i feel the blood draining out of my hands n legs; my breathing becomes shallow, pulse races and I feel light headed. The experience is frightening and lasts forr A couple of minutes, subsides and isometimes, s repeated agsin after a few minutes.
    I feel the urgeto defeacate two to three times. That relieves me a little.
    Since last week, I wake up evry night, from sound sleep around 3 am, generally after my first phase of sleep is over. I feel yhe pulse rise suddenly and hands and feet turning cold. I am really confused about what is happening.

    1. Rashida

      I forgot to mention a tightness in the chest during some of these episodes. At night, since the whole last week, i have been unable to sleep properly. The moment i fall asleep, i wake up again suddenly with the onset of these episodes. My cardiologist discharged my case after the results from a holter and stress test showed nothing. I have been ad,mitted to emergency throice in the past six months but the routine examinations reveal nothing.

            Adrenal glands rarely “fatigue”. It is far more likely that there is dis-regulation in parts of the brain responsible for sending stimulatory signals to the adrenals. Oftentimes this is a result of a disrupted circadian rhythm, but not always.

      2. Sally Sensy

        Rashida, i had very similar symptoms several years ago and it turned out i was in peri-menopause and the symptoms were caused by extreme hormonal fluctuations (of which my body is extremely sensitive). MDs are not taught to diagnose perimenopause so it is frequently missed. If u are 35-55 its likely hormonal. Symptos start at night when estrogen is lowest. In addition many conditions cfs, fibrimyalgia, anxiety, depression, thyroud, adrenal, gut issues, etc etc are all made worse by female hormonal fluctuations. Find a GOOD female OB/GYN as starting place. Cardiologists will likely think you are crazy and most will say you have anxiety which u may well have after all your experiences! Good luck 🙂

    Great article, one note though. MSG is a neurotoxine

    1. HumanThatUsesGoogleToLearnAndSpreadKnowledge

      It is not a neurotoxin. MSG is a salt and an amino acid that separate when introduced with a polar liquid such as water. Monosodium Glutamate can be found when you mix most proteins with table salt or natural salts in meats.

      Just dont inject table salt into your brain as they did in the research that claims it is dangerous.

  • samar

    Hi, I use a Polar H7 and RHRV to determine measures of parasympathetic activation. I was intrigued by your experience and wondered which part of the occipital bone area would be most beneficial.
    I massaged first the lowest part close to the neck for a minute and then waited for a minute, then the part slightly higher in the same way, and then the part closest to the upper reaches of the occipital bone in the same way.
    The results of SD1 and SD2 as determined from the non linear approach were as follows:
    First – lowest: During massage: SD1=11.4 : SD2=28.1 For 1min after: SD1=14.7: SD2=47.6
    Second – Mid height: During massage: SD1=10 : SD2=45.4 For 1min after: SD1=18.1: SD2=51.9
    Third – Uppermost: During massage: SD1=12 : SD2=45.5 For 1 min after: SD1=10.9: SD2=21.8

    Incidentally SD1 is a measure of Parasympathetic and SD2 a measure of sympathetic activity.

    It would seem that the middle region is the most effective and the results take some time to come through i.e. they are not apparent while you are engaged in the massage. There is however some slight increase in heart rate during massage.

      How are you coping with gastroparesis? My 22 yr old son has been diagnosed with gastroparesis 16 months ago. He has been in and out of hospital since then (20 times )

      1. Daniel Lappin

        HI, I’ve had crippling gastro paresis for 20 years. Over the past few years I’ve found relief. This info may not apply to your case.
        Try bitter hers to stimulate the digestive tract/vegal nerve. Product: Flora Swedish bitters.

        Also, CDB Cannabis ingested or topical to the mid-lower spice.can help.

        Also, from my experience, essential oils trigger the vegus and stimulates gastric motility.. inhaling and topical applications have a mild effect. Oral ingestion of the essential oils is a powerful treatment. only a few drops, don’t swallow, absorb in mouth, then spit out. Try Basil, rosemary, thyme, cardamon.
        yet you need to consult an aromatherapy practitioner for safety reasons unless you do alot of reading. search: ingesting essential oils..

        Supplement with Choline – the nutrient source that feeds the vegal nerve.

        Embedded stress and trauma can play a role. See my website: DanielLappin.com

  • Sooz Gould

    My Vegas Nerve was cut accidentally during a Nissan Fundoplication surgery…what do you suggest that would help me with not having a working nerve? I am hyperthyroid, have bowel issues for which I take 3 different medications, am always either too hot or too cold and can not seem to lose weight. I am a 67 year old female with a moderate activity level.

    1. Very sorry to hear Sooz about this terrible mishap and the consequences today. I have no answer to offer, but I wonder, as our body is so amazing, might it be possible to GRAPH the cut side, across to the other side, to the good vagus nerve? Surely the Vagus can manage that (and of course, they can pay for it too). With best wishes.

  • Yes indeed, that looks so amazing, I’m just sorry I didn’t think of it first! They say it will be available this Spring. In the meantime, there was yet another article – nit directly on the vagus but not far – about a “patch placed on the forehead”, releasing some kind of elecrical impulse too, and having wonderful results on sleep and mood, by releasing dopamine and oxytocin. Exciting times !

  • Lori Patterson

    So, back in 2006 I had a VN stimulator implanted for depression. I have continually wondered what the constant stimulation (every 5 minutes for 30 seconds) has done FOR me and TO me. And now that I’m 10 years into this ‘treatment’ and feel like it is going off sporadically, probably due to battery issues, what am I facing when it no longer stimulates?? Thank you for this article! It’s the most informative I’ve ever read on vagal stimulation.

    Wow very informative. I actually was diagnosed with vagus nerve depressor syndrome. I actually need to do the reverse and not stimulate the vagus nerve.
    I was getting spells where all of a sudden my blood pressure would drop, I would lose color in my face and turn pale, feel dizzy, light headed and then heart rate would speed up. It would last 15 minutes. Lifting weights at gym I would get weak. Lots of other things. Finally a heart doctor did a tilt test and discovered everything was caused my this vagus nerve conditiion.
    Its a bummer because I do a lot of things mentioned in your article and didnt realize that could affect my vagus nerve. Wish there was a way to cure this condition.

    1. Barbara Power

      Interested in your comment of a tilt test. I had a test where my blood pressure was measured, then I was told to lie down flat, then get up fast. My blood pressure dropped too many points. apparently related to low adrenals. Would this have anything to do with the Vagus nerve?

    Daughter has an over reactive Vegas nerve that she was born with. Anything invasive, immunizations, injury etc caused a grand mal seizure. Heart rate dropped, quit breathing at the start and lost bladder control. Mimicked epelipsy but was ruled out. As an adult seizures are almost non existent but she still gets the feeling that she use to get just prior to having one occasionally and breathes through it. It’s been 6 years since last major seizure. Would love your thoughts. Low vegal tone= over reactive vegal nerve.? Father and uncle has similar issues, passing out without seizure.

      I am struggling with this same issue at this time, seems mostly related to my gut flow, I have had major constipation issues, and if not relieved, I have a huge Vagas response , causing pulse in the 40-50’s, and I sink to the floor. As I get older, these episodes are lasting longer and longer. Is there any info that you know of to AVIOD a Vagas response, or to reverse the response once it’s started? Besides to try and stay regular with my bowel movements , I am at a loss on how to bounce back from these scary episodes. Also what type of physician treats the Vagas nerve? This last episode lasted so long with such low pulse that they had to call ambulance . Thank you for any info.

      1. Laura

        Hi Jessica, see if you can find a dr to do a Tilt Test, my heart dr did this and diagnosed me with vagus nerve depressor syndrome. So I get those episodes similar to you when I activate my vagus nerve

        1. Emily

          My husband has this issue as well. Blood pressure drops, ringing in the ears before he passes out. He’s had his heart and brain checked and no doctors could tell us what caused this. Eventually I worked it out from Google. Now when it starts to happen I get him to make fists, opening and closing. I get him to lie on the floor and raise his feet above his head as well and to take deep breaths. This has worked for him and stops him passing out and he feels better within 5 minutes.

      Has it worked for you?

  • Aaron Morgan

    Regarding (17) Acupuncture, the abstract shows:

    “A medico-legal autopsy disclosed severe haemorrhaging around the right vagus nerve in the neck. Other organs and laboratory data showed no significant findings. Thus, it was determined that the man could have died from severe vagal bradycardia and/or arrhythmia resulting from vagus nerve stimulation following acupuncture.”

    Does that mean that just the act of stimulating the nerve caused haemorrhaging / bradycardia / arrhythmia, and, subsequently, death? Or, was it possibly the Acupuncture needle itself that did some sort of structural damage?

    Forgive me, if this is a silly question. I’m a layperson and not proficient in such topics.

    Many thanks,

    Especially after reading this article, I became convinced many of my most pronounced inflammation symptoms were vagus related.

    For those who are interested, my latest “Vagus nerve hacks.”

    — I’ve been implementing many of the items on Joseph’s list, which do help to calm the inflammation, especially ICES, breathing exercises, Oxytocin and a few others.
    — One thing seems to have helped me the most: returning to Proteolytic Enzymes (specifically Enzyme Defense, formerly “ViraStop”). (Disclaimer: Not sure at all what Joseph thinks of these…)
    — I used to take this product twice daily for years, then stopped. For a recent trip, I felt a cold coming on, so I started up again, and for the first time in months, my worst symptoms subsided. To test the hypothesis, I stopped the PE upon returning home, and the symptoms returned with a vengeance. Started up again, they’ve remained calmed.

    — Doing some more VN research, I found the following article, positing that “CFS”-type fatigue symptoms can be spurred by an infection on the vagus nerve itself: (from a site that’s really excellent, by the way):

    http://health-matrix.net/2013/08/06/heart-attacks-cfs-herpes-virus-infection-and-the-vagus-nerve/

    From a quoted study in her article: “The Vagus Nerve Infection Hypothesis (VNIH) of CFS is as follows: While the sensory vagus nerve normally signals the body to rest when it senses a peripheral infection, that fatigue signal is pathologically exaggerated when an infection is located on the vagus nerve itself.”

    — Bottom line: I’m no doctor or scientist, but could there be some connection between some of my symptoms, the Proteolytic Enzymes, and a VN viral infection?

        Raymond, this is an excellent article, thanks.
        I notice your specialty (craniosacral work) — I’ve been helped most recently by a chiropractor adjusting my C1. I’ve found it keeps my symptoms at bay.

          Hi Keith. Glad you liked it and that you got help from your chiropractor. But the real surprise is the ‘other’ thing which I practice more now. Find out and be better for it at my little site called TREIreland dot ie 🙂

    Thank you so much for this article and for all the research you put into it! I very strongly suspect that the vagus nerve is damaged by fluoroquinolones in those who suffer from fluoroquinolone toxicity. I wrote this post about the possible involvement – If anyone who is reading this got sick after taking cipro, levaquin or another fluoroquinolone, there is help available. Please reach out via floxie hope. Thanks!

    Joseph,
    Excellent article, one of the most valuable for me! Interestingly, I was having a Rolfing session this past week, and he stimulated my VN by pressing around my Occipital bone — I became so dizzy, I almost passed out, but felt fantastic afterwards — anyway, will be using your suggestions, thanks!

    What an interesting article! I came across this through a kind of weird path, but am glad I found it. I have used what I call ice therapy on my face before, usually to help with muscle tension, and found that it helped with anxiety and congestion as well, and now I have an answer to why it does that. I have also used mindfulness, yoga, massage, breathing techniques and tapping (which you may want to look into) for my anxiety, stress, tension headaches, and IBS.

    So many people are talking about the vagus nerve causing so many issues, and saying that stimulating it will help. But what is wrong with it, as in the root cause? Why are signals getting through?

      My daughter has Pots, Autonomic neuropathy, and sensory neuropathy. About 50% of the time the above onsets after a bad virus. She started showing signs of Pots a month after having Hand,Foot, Mouth disease. This virus, as any virus really could, ultimately caused nerve damage. Anything that can cause nerve damage, even autonomic, can affect the Vagas nerve. It’s been five years now and everything she has matches up to her Vagas nerve being affected (since it wanders all over the upper half of the body). I believe her nerve damage, also damaged that Vagas nerve setting off a whole new world of symptoms.
      Our bodies are amazing.
