I just found this group. Hello! I have been dx'd with IBS for several years. It started after a bout of acute diverticulitis. Had C-predoinant for several years, but in the past year or so have problems with Diarrhea. About 8 mo ago I became sensitive to protein - beef, fish, lamb. Would get diarrhea from eating even a tiny bit. Allergy testing was negative. Then I began eating a lot of chicken and recently became sensitive to that too. Numerous tests (blood, colonoscopy, upper GI) came back normal. Now I am extremely limited in what I can tolerate - eating bland diet with only eggs for protein. Also other things i used to be able to tolerate i cannot tolerate now either (eg canned pears). docs not able to help despite numerous visits and testing. Does this sound familiar to anyone? Would this be considered part of IBS? Appreciate any comments Thank you very much.RosieP.S. It's not just simple diarrhea that I get. Aftr the D resolves I have nausea, gas, sweats, and bloating for about a week.
