Like colitis, Crohn’s disease is an inflammatory bowel disease caused by the body’s immune system mistakenly attacking good bacteria located in the gastrointestinal (GI) tract. Inflammation and ulceration results, causing symptoms that include diarrhea, more urgent bowel movements, constipation and abdominal pain. While Crohn’s disease typically affects the end of the small bowel and beginning of the colon, it can affect any area of the GI tract from the mouth to the anus.

Crohn’s disease is a chronic condition. Patients will experience flare-ups of symptoms and periods of remission.
