Understanding Crohn’s Disease
First off: What is Crohn’s disease?
Crohn’s disease is an inflammatory bowel disease (IBD) that causes chronic inflammation in the gastrointestinal (GI) tract.
Crohn's Can Affect Any Part of the GI Tract
Crohn's can affect areas from the mouth to the anus. But it most commonly affects the end of the small intestine (ileum) where it links to the beginning of the colon.
Crohn’s Can Also Affect:
Even though the reasons aren’t entirely understood, the impact of IBD is not always confined to the GI tract. Some people develop symptoms related to the disease in other parts of the body. These are just a few of the areas where extraintestinal (outside of the intestines) complications may be evident.

Differences Between Crohn’s Disease and Ulcerative Colitis (UC)
Ongoing inflammation of the GI tract happens with both Crohn’s and UC, but there are some key distinctions.
Crohn's Disease
- Affects any part of the GI tract (from mouth to anus)
- May appear in “patches”—leaving some sections of the GI tract untouched
- Inflammation may extend through entire thickness of bowel wall
- About 67% of people in remission will have at least 1 relapse over the next 5 years
Ulcerative Colitis
- Limited to the large intestine (colon) and the rectum
- Pattern may spread continuously to involve entire colon
- Inflammation only occurs in the innermost lining of the intestine
- About 30% of people in remission will have at least 1 relapse over the next year

IBD Is Not IBS
It’s important not to confuse an inflammatory bowel disease (IBD)—like Crohn’s or UC—with irritable bowel syndrome (IBS). IBS is a disorder that affects the muscle contractions of the bowel and is not characterized by intestinal inflammation, nor is it a chronic disease.
