The cause(s) of microscopic colitis is unknown. Some doctors suspect that microscopic colitis is an autoimmune disorder similar to the autoimmune disorders that cause chronic ulcerative colitis and Crohn’s disease. (Please read the Ulcerative Colitis and Crohn’s disease articles for more detailed discussion.) One study has implicated long term (longer than 6 months) use of nonsteroidal antiinflammatory drugs (NSAIDs) as a cause of microscopic colitis. Some patients’ diarrhea improves after stopping the NSAIDs.
