I'm just wondering if anyone can tell me what causes IBS? Is there actually a reason that some of us have these problems and others are just fine? I have listened to my husband for over 10 yrs. tell me that I just need to eat more fiber, and just go to the bathroom- what's my problem? I didn't get a clear answer from my dr. I am so grateful to all of you for sharing your experiences with us all. I feel so much better just knowing that you are all here for support, and we are all going through the same thing. I always thought I had to deal with this on my own and it was just the way my body was. Now I know there is something wrong.Sherry
