I recently had 3 months of chronic diarrhea and digestive upset (I have a 10-yr history of mild IBS-D and
lactose intolerance), and got a full battery of tests. The only abnormality was microscopic colitis on one of the colonoscopy biopsies. All other tests and antibodies were negative, SED rate was normal, liver and kidney chemistries normal, C-reactive protein normal, no anemia, CBC normal, etc.
Doc wants me to start Asacol but the side effects seem worse than my mild diarrhea.
