Inflammatory Bowel Disease (IBD)

Ulcerative colitis and Crohn's disease are called inflammatory bowel disease (IBD). Ulcerative colitis and Crohn's disease have many similar symptoms (including diarrhea, rectal bleeding and abdominal pain). These diseases are not contagious. 

About 1.4 million Americans have IBD. Thirty thousand new cases are diagnosed every year.

Young people between the ages of 15 and 35 are most likely to get IBD, but anyone can get it. It is more common in Caucasians. IBD is especially common in those who are Jewish.

Ulcerative colitis and Crohn's disease both have times when disease symptoms go away (remission). They also both have times when symptoms become more severe (flare).
