I had a colectomy 7 years ago (had 7/8 of my colon removed because of colonic inertia). I've had all the tests to rule out other diseases so my doctor says I must have IBS. Changing my diet has helped some but is it possible to have IBS in my situation? I haven't had a lot of trouble with d or c since my surgery but my main problem has been abdominal pain, severe tenderness in that area, and I haven't been able to wear anything around my stomach or waist for the past month or more. I do know my stomach ache started after a week of unexplained diarrhea about four months ago. Please advise, thanks!
