I have recently been diagnosed with collagenous colitis. Symptoms have been severe, chronic diarrea, bowel incontinence at night, abdominal pain, etc. I had a flexsig and a colonoscopy, both confirming diagnosis. (celiac disease is not present) Other than this, I am healthy 45 year old female.
Please tell me what you know about the connection between collagenous colitis and any autoimmune diseases, arthritis, etc.
