Frequent throwing up
a friend of mine has this problem that he throws up regularly (from what he's told me about three times a week on average)
this is a permanent condition for him, and has been for a few years now (i'm not sure how many..i'd have to ask that)
he ended up in hospital once because he wouldn't stop throwing up, and they found nothing wrong with him..
neither of us have any idea why he keeps throwing up..it isn't self-induced, and he tries to keep himself from throwing up all the time..but doesn't manage..
the only things i can still think of are possibly an allergy to something in what he eats? although surely the hospital would've thought of that?
or that it is because of phsycological reasons..though i wouldn't know which..
from what i know, he doesn't eat much, and when he does eat, he often ends up throwing up..
i'm hoping to hear some suggestions as to what could be wrong with him, and what he can do against it.
