I have had diarrhea for over 40 years. I had an 18 month remission, and then it came back. I have recently had every test you can imagine and nothing seems to be wrong. If I don t eat the diarrhea is delayed, but immediately after eating, I sometimes can t even make it to the bathroom. Lately, I have noticed what appears to be mucus in the bowel movement. I have never had pain just immediate passage of movement, usually very loose and sometimes just watery. No weight loss, and I am in good health, and I excersize on a treadmill every day. Any ideas? Thanks
