Can anyone explain the vegas nerve in relation to the digestive system??
June 15, 2005 at 5:49 pm #24833b_d_41501Participant
One way is the stimulation of bile secretion – secretin from duodenum, by parasympathetic
vegas nerve, increased blood flow in the liver, etc.

As for digestion, in lay terms the Vegas Nerve helps to balance the levels of stomach acid, without it medication is needed.
I am trying to learn more about what the Vegas Nerve does in its entirety as mine was severed in surgery while tumors were removed. I have seen some messages on the net about the vegas nerve may play some part in heart rhythms, as well some emotions and other body functionality.
For the moment I am only medicating to take care of the stomach acid function, and as I will be without the nerve the rest of my life, I want to learn what other circumstances I should consider mitigating.
thank you, livingthedream

I Have Just had my Gall Bladder removed but are still having the same symptoms in my breast bone area and my shoulder blades only now it doesnt burn like it did it is just pressure in my right side and shoulder blades and chest when I try to eat something it is like my digestive system sets something off and I have pain and pressure and feel dizzy at times it comes and goes, could it be my Vegas nerve causing dizziness and the weird feelings i am having, when i try to eat. my GI Dr. cant find anything no ulcer, hernia , so they took out my gall bladder but i am still having symptoms, I have spent so much time of work and insurance paying for test and no answer yet. to what it is. I am at my limits meantally HELP ME PLEASE. I did have a defib/pacemaker installed last august too which has been traumatic and I wonder if the nerves they cut in my chest may have anything to do with it..?

I jsut went yesterday for a Lap Band consultation. It was there that I first herd about the Vegas Nerve. The vegas nerve sits at the top of the stomach, its is responsible to letting the brain know that the stomach is full. When you eat and your stomach gets full, it puts pressure on these nerves and activates them to inform the brain that you are full. Does this help?

The Vagus nerve is used to stimulate the release of gastric juices in the stomach. It also controls heart rate by braking (slowing down) the heart beat.
The way I remembered this in anatomy class was
Going to Vegas and losing your money will brake your heart, and give you ulcers 8)

There are two, though, and if the stomach one was affected, the bile one should be okay.

An important point – Gastic acid is still produced without activation of the vagal nerve…
For those who are interested…
The hormone gastrin binds to (CCK-2) receptors on the stomach and activates a proton pump (via increases cAMP levels) to increase acid in the stomach…
Gastrin also increases histamine release which binds to (CCK-2) receptors, which also increase activity of the proton pump (bind to H2 receptors – causes increased Ca2+ in parietal cell)…
Vagal nerve activity also increases activity of proton pump (but it has a different mechanism – directly via activation of mACh) receptors and by increasing histamine release (also activation of mAChRs)…
But the basic point I’m trying to make is that activity of the vagus nerve is not essential in gastric acid secretion…
In fact you can survive without a stomach as it is not essential for digestion… the only substance that you cannot absorb without a stomach is vitamin B12…

My husband and daughter get really bad headaches and then very nauseous to the point of vomitting. I was always looking for solutions for this i.e. peppermint tea, ginger, more rest, massage, etc. We happen to go to the chiropractor recently since my husband and I had neck and back pains and mentioned the senerio about our daughter to him and he checked her neck and said that she is majorly out in her neck. He said that the vagus nerve was being pinched and that is the nerve that controls the stomach acids and the calmness before bed. He adjusted her neck and she immediately felt the pressure release. My daughter is 8 yr. old and was suffering for months with this and the fix was as simple as an adjustment! Of course my chiropractor is the greatest and most thorough that I have ever been to. Right now, we are going weekly for her until her adjustments start holding by themselves, we have only had 2 adjustments so far but I can tell it cures her because we were out of town for a week and a half and she started getting a headache and she vomited, again, the adjustment helped stop that immediately. The Dr. said this kind of thing can happen from growing spurts and crazy kid stunts to trauma. I hope this helps anyone else out there.

You should take your daughter to a MD.

did you ever figure this out? I am having similar symptoms and others, dr’s just look at me like I am crazy…I have hoarse voice, trouble swallowing etc…but also, after I eat I have shoulder pain,, headache, feel dizzy etc…I even faint…I just got diagnosed with gastroperesis….which is a disorder that happens when your vagus nerve is damaged, so now I tryin to find out more about vagus nerve and where it might be damaged and what kind of drto see…

I have been having breast bone "area" pain, pain in my left rib cage area, back, neck and shoulder pain, full feeling like I’ve over eaten at every meal, when others eat and drink more than I do. The Dr’s thought I had an ulcer. They did an upper and lower "scopy" they found irritation in my stomach….did the biopsy…found H. Pylori. Treated me for that. Some of the pain went away. I had a neg for H. Pylori in Feb, so I guess thats gone. Still having the breastbone pain and left ribcage area…..the did the scan for gallbladder, all is well. They did find 6 simple cyst on the liver when they did the ultrasound. Finally after much testing and blood work I have been diagnosed with Gastroparesis they are prescribing me Reglan, the side affects are scary, I haven’t taken any as of yet. I will try every other avenue first. Juicing, pureeing my food, or whatever. After reading all the posts here I am going to see the Chiropractor because I was in a car wreck in 84 and have had problems with that all these years….maybe the Vagus nerve was damaged somehow. I am only 42 and cannot imagine living the rest of my life this way. Any and all info or advice is greatly appreciated.

I got a article.
* major reference ( in human nervous system (anatomy): Vagus nerve (CN X or 10) )
The vagus nerve has the most extensive distribution in the body of all the cranial nerves, innervating structures as diverse as the external surface of the eardrum and internal abdominal organs. The root of the nerve exits the cranial cavity via the jugular foramen. Within the foramen is the superior ganglion, containing cell bodies of general somatic afferent fibres, and just external to the…
* neurological examination ( in nervous system disease: Cranial nerves )
To examine glossopharyngeal and vagus nerve function, the physician tests for the presence of touch sensation on the soft palate and the back of the throat (the latter usually eliciting a gagging reflex), the elevation of the palate on phonation (which should be symmetrical but rises to the stronger side in the presence of weakness on one…
* types of cranial nerves ( in cranial nerve (anatomy) )
Cranial nerves are made up of motor neurons, sensory neurons, or both. The vagus nerve is one of the most important; it extends to many of the organs in the chest and upper abdomen.
* heartbeat regulating system ( in cardiovascular system (anatomy): Nervous control of the heart )
Nervous control of the heart is maintained by the parasympathetic fibres in the vagus nerve (parasympathetic) and by the sympathetic nerves. The vagus nerve is the cardiac inhibitor, and the sympathetic nerves are the cardiac excitors. Stimulation of the vagus nerve depresses the rate of impulse formation and atrial contractility and thereby reduces cardiac output and slows the rate of the…
* human digestive system ( in human digestive system: Blood and nerve supply )
…stomach is provided by both the parasympathetic and sympathetic divisions of the autonomic nervous system. The parasympathetic nerve fibres are carried in the vagus, or 10th cranial, nerve. As the vagus nerve passes through the opening in the diaphragm together with the esophagus, branches of the right vagus nerve spread over the posterior part of the stomach, while the left vagus nerve…
* hunger ( in motivation (behaviour): Hunger )
…analysis is inadequate to explain hunger motivation. For example, it is known that much of the stomach can be removed without the loss of hunger motivation. Similarly, it is known that severing the vagus nerve, which causes stomach contractions to cease, does not eliminate the experience of hunger.
* parasympathetic nervous system ( in human nervous system (anatomy): Parasympathetic nervous system )
Preganglionic parasympathetic fibres of the 10th cranial (vagus) nerve arise from two different sites in the medulla oblongata. Neurons that slow heart rate arise from a part of the ventral medulla called the nucleus ambiguus, while those that control functions of the gastrointestinal tract arise from the dorsal vagal nucleus. After exiting the medulla in the …
* sensory reception ( in human sensory reception: Nerve supply )
…two-thirds of the tongue is supplied by one nerve (the lingual nerve), the back of the tongue by another (the glossopharyngeal nerve), and the throat and larynx by certain branches of a third (the vagus nerve), all of which subserve touch, temperature, and pain sensitivity in the tongue, as well as taste. The gustatory fibres of the anterior tongue leave the lingual nerve to form the chorda…

Thanks, I know this was for blue but I printed this out and will give it to my Chiropractor this morning. I told him about my dignosis, (Gastropareis) of which I will be getting a second opinion, and he said hmmmmm I will have to look that up. This should help him.

My Husband had a thyroidectomy 6 months ago. Immediately after surgery in the recovery room he complained of pain in the neck (left side) not the site of the surgery. Ever since he has weakness in his neck can’t seem to hold it up, when he sleeps it flops over to the left and it cuts off his airway which in turn wakes him up it up, his voice becomes very weak after speaking for awhile. He has had problems with GERD in the past but now it seems that has tremdously increased since this surgery. The acid wicks up into his mouth. Is it possible the Vegus Nerve is damaged? What type of Dr. to we see? Are there any tests that can be done to determine this? He is really suffering and we are in need of advice.

I am having the same problems swallowing and have been diagnosed with Gastroparesis. I have been to alot of Doctors and I know what you mean about the doctors looking at you like you are crazy. I have been doing my own research because I feel like know one is helping me for over two years. Recently I had a ultrasound of my thyroid and they found noduals I am seeing a endocrine dr blood work came back normal so they say there is a wide range for your thyroid going for a second opt. Gastroparesis is also caused from diabetes and hypothyriod so you may need to see a endocrine dr. Girl I know what you are going through and it is very hard keep your head up 🙂

I had a abdominal hysterectomy in july 2009. Every thing was fine until i started driving again 6 weeks later. I went back to work and had to drive 16 miles. i began to have dizzy turns at the wheel. I thought it was just tiredness post op. Then on nov 5th 2009 i arrived home from work and was sat at the computer talking to my son when i started to get pins and needles in my hands. I said goodbye to my son and went upstairs to bed. I still had the pins and needles in my hands. i bent down to put my pjs on. All of a sudden my heart was racing and i felt like i couldn’t breath. i also had chest pain. i called my daughter who was down stairs. She said i was pale and looked awful. An ambulance was called. Doctors diagnosed anxiety and depression and discharged me. Over the next few days the attacks were relentless but only if i was lying on my side or sitting. i did go back to hospital several times but the only diagnosis was anxiety and depression. I did as i was told and commenced anti depressants even though i didn’t feel depressed or particularly anxious. the last few years have been hell and the attacks are getting worse. They scare me. I am trying so hard to carry on as normal but it is so hard. When this all started in 2009 i did ask if there could be a problem with my vagus nerve but no doctor believes this to be the case. I am at my wits end as it is affecting my life massively. I only ever drive if i need to and never any further than work. This is because if I sit too long then i have an attack. I cant sleep on my side as this initiates an attack. Also eating a meal makes things worse so i don’t eat much now as too scared. my bowels don’t work unless i take something and i have been incontinent of urine several times. All these symptoms started 6 weeks post hysterectomy and i just want answers but most of all i want my life back. If anyone has any answers then please feel free to post. Any snippet of info gratefully received. Thank you

katrina – i think you should look into POTS – postural orthostatic tachacardia syndrome. the symptoms sound somewhat like what my daughter experiences. good luck!
