I am not sure if i have IBS but I have been hospitalized for severe abdominal pain and chronic diarrhea. Doctors at the hospital performed many tests and could not find the reason. I have lost my appetite completely and I am to afraid to eat anyway because of the pain and bloating feeling. Its almost like i can feel my food digesting. I have had an endoscopy and colonoscopy which proved that I don't have ulcers. But pain continues. I am losing hope and my mind because diarrhea has lasted a little over a month now and I still have no answers from the dozen of doctors who have seen me. I am returning to the hospital today in hopes of some treatment. I have tried lomotil which causes me to vomit (and the diarrhea continues so i stopped it.) Can anyone tell me if this is IBS? Please help! Also, I have lost about 15 pounds in the last 2 weeks. Had to be given IV Fluids.
