Wow, you are good researchers. Yes, that sounds very appropriate. It's the vagus nerve that you're talking about - and it certainly does supply the stomach. You should send the endocrinologist a bill!

Anyway, thought it might come in handy in case you get the question again from someone else.  Thanks for you help!

Therefore, her temp is way off (freezes all the time) and she experiences a "fullness" feeling even though she can only eat tiny amounts.  This nerve seems to tell the stomach when it is time to process food, start digestion, and so forth.  I believe there is a term though I can't remember it right now....  it is a form of stomach paralysis....
