Hi, I don't know if my post will be helpful as many of you may have already traveled this route, but here it goes... I suffered the ill effects of IBS from my pre-teen years up to my late twenties. At 29 I saw an allergists. As it turns out, I am allergic to peanuts, pecans, and bananas-foods I was eating almost daily! I have been IBS symptom free for a few years now. I am only sorry I did not see an allergist sooner and a little annoyed that I was not tested as a child, but there is nothing I can do about that..... I wanted to post this in the event that it may help.
