Term: Inflammatory Bowel Disease (IBD)

Glossary Definition

Last Updated: 2024-06-07

Definition:

A group of disorders characterized by inflammation of intestines (i.e., the intestines become red and swollen). The most common inflammatory bowel diseases are Crohn's disease and ulcerative colitis. Crohn's disease is a chronic autoimmune disease that can affect any part of the gastrointestinal tract but most commonly occurs in the ileum (the area where the small and large intestine meet). Colitis is an inflammation of the large intestine that is caused by many different disease processes, including acute and chronic infections, primary inflammatory disorders (ulcerative colitis, Crohn's colitis, lymphocytic and collagenous colitis), lack of blood flow (ischemic colitis), and history of radiation to the large bowel.
