For almost 4 months I've gone from having normal bm's daily to maybe going once or twice a week and diarrhea. I don't understand what's going on. Recently had a colonoscopy. If my bm is normal than few mins later diarrhea. Anyone know what this means? Diagnosed almost 10 yrs ago. Fistula connecting large and small int.Stricture in transverse colon.Do have good news multiple polyps removed and not cancer woohoo!!!
