What Is IBD?

Inflammatory bowel disease (IBD) is caused by inflammation (swelling) of the colon and small intestine. The two major types of IBD are Crohn's disease and ulcerative colitis.

The major difference between Crohn’s disease and ulcerative colitis is that Crohn's disease can affect any part of the gastrointestinal tract (stomach and intestines), while ulcerative colitis is restricted to the colon and rectum. Both can cause problems in other parts of the body.

Although Crohn's disease and ulcerative colitis are very different, they do share similar symptoms, such as:

  • Abdominal pain
  • Diarrhea
  • Rectal bleeding
  • Vomiting
  • Weight loss
