Together with the related condition lymphocytic colitis, it is a subtype of microscopic colitis, which is characterized by inflammation that specifically affects the colon (i.e. colitis), and a clinical presentation that involves watery diarrhea but a lack of rectal bleeding.
Image of colon cancer identified in the sigmoid colon of a person with Crohn's disease during a colonoscopy. Bowel damage due to inflammation occurs in half of cases within 10 years of diagnosis, and can lead to stricturing or penetrating disease forms. This can cause complications such as:
