I'm not sure what it is. I have had it for about 2 months now. It started shortly after I got the stomach flu. I wake up hungry and sick so i eat, then get hungry allot more through the day. No matter what I'm hungry and sick the next day. If I don't eat I have to go to the bathroom a lot. If anyone knows what this is pleas tell me.
It could be caused by many various things. Ulcer, gallbladder, intestinal problems,....the list goes on and on. Nobody here or anywhere can tell you what the problem is without proper tests and medical knowledge and assessment. I suggest you seek the advice of a medical professional.
Since very bad advice is often given on a gaming forum, I'm closing this one. Sorry.
