Fecal incontinence is the most embarassing thing about IBS. It's not like a little leaking with urinary incontinence that some women experience. I have also had urgent, unexpected, uncontrollable diarrhea. Medical providers don't always believe that this happens to you. While on Lotronex, it only happened a couple of times. I'm not always sure what the "trigger" is, but a large meal can sometimes precede it as well as traveling in a car. I carry extra clothing and baby wipes whenever I go somewhere, just in case. If they really understood what this was like, they would return Lotronex to us!
