i have been having diarrhea for almost a year now and i have been diagnosed with IBS, i have tried exclusion diets, anti-depressants, anti-spazmodics, immodium, calcium carbonate suppliments, exercise, hypnotherapy and nothing works. i have previously had endrometriosis of the ovaries and i am wondering if it is possible it could be endo of the bowel? I have also tried questran to see if it is an issue with my gallbladder but that doesnt seem to be helping.
