Crohn’s Disease and Ulcerative Colitis
Inflammatory Bowel Disease (IBD for short) refers to inflammatory disorders of the bowel.
Two major types of IBD are:
Crohn’s Disease (CD), occurs as a patch or patches of inflammation in any part of the gastrointestinal tract (from the mouth to the anus), but most commonly in the small and large bowel.
CROHN'S DISEASE: Crohn's disease occurs most commonly in the small and large bowel.
In Ulcerative Colitis (UC), inflammation occurs in the large bowel only. It may affect the entire large bowel, which is known as Pancolitis. It may affect the left portion of the large bowel leading down to the rectum, referred to as Distal Ulcerative Colitis (left-sided colitis and/or proctosigmoiditis). If only the rectum is affected, it is called Ulcerative Proctitis.
PANCOLITIS: Inflammation of the entire colon.
DISTAL ULCERATIVE COLITIS: Inflammation of the left portion of the large bowel leading down to the rectum.
ULCERATIVE PROCTITIS: Inflammation of the rectum only.
