What is Crohn’s disease

Crohn’s disease is an inflammatory autoimmune bowel disease characterized by severe and persistent inflammation of the lining or wall of the gastrointestinal tract. Crohn’s is sometimes referred to as chronic ileitis, regional enteritis, or granulomatous colitis. The part of the gastrointestinal tract most commonly affected is the segment between the ileum and the rectum. Although Crohn’s disease can be difficult to manage and live with, it is usually not life threatening.
