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.

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
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.
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...
