Inflammatory Bowel Disease (IBD)

Inflammatory Bowel Disease (IBD) is a chronic inflammatory disorder of the intestines that does not have an identifiable cause (such as infection). Pediatric IBD causes the immune system to become inappropriately active, causing injury to the intestines.


Inflammatory Bowel Disease

There are two primary types of Inflammatory Bowel Disease or IBD:

Ulcerative Colitis

Ulcerative colitis affects only the lining of the large intestine (the colon).

Crohn’s Disease

Crohn’s disease can affect any part of the gastrointestinal (GI) tract. Most often Crohn’s disease affects the small or large intestines. It can cause inflammation in the lining and deeper layers of the intestines.

Quick Facts

  • An estimated 1,000,000 Americans are living with IBD.
  • Nearly 1 in 4 patients diagnosed are under 20 years old.
  • The exact cause of IBD is unknown, but both genetic and environmental factors may be involved.
  • IBD can affect parts of the body outside the GI tract, such as the skin, joints, eyes, or liver.
  • Don’t confuse IBD with irritable bowel syndrome (IBS) – a different and less severe condition.
  • Inflammatory bowel disease in kids can often be managed effectively through medication or other treatments.
