Hi Pedro,I did a series of six colon hydrotherapy sessions about two years ago. It didn't really do anything. I completed a two-month colon cleanse this spring and the first month I felt great, no symptoms, then everything returned during the second month. I think it's probably just as individual as far as hope/hype as IBS symptoms are in general...very diverse. The good thing is it probably won't hurt you, but I don't think you can figure out if it will help ahead of time.
