Recently I have been getting very nauseous right after eating, no matter what I eat. I am mostly vegetarian, but do eat small amounts of meat here and there. I have also had lots of bowel movements, 4-5 in a day, that range from solid to diarrhea. I also tend to break out into cold sweats and get shakey if I wait too long in between meals. I am 32, 5 3 , 170lbs.
