What is Crohn's Disease?

Crohn’s disease is an ongoing disorder that causes inflammation of the digestive tract, also referred to as the gastrointestinal (GI) tract.

It can affect any area of the GI tract, from the mouth to the anus, but is more commonly found in the end of the small bowel (ileum) and the beginning of the large intestine (colon).

The damaging inflammation resulting from Crohn’s may cause pain and may make the intestines empty frequently, resulting in diarrhea and other Crohn's disease symptoms.

Crohn’s is one of the inflammatory bowel diseases.

As an inflammatory bowel disease, Crohn’s disease symptoms are similar to those of other intestinal disorders, such as ulcerative colitis (UC).1 For that reason, Crohn's may be difficult to diagnose.

Unlike UC, which affects only the large intestine (colon and rectum), Crohn’s can affect the entire digestive tract, with normal, healthy bowel found between sections of diseased bowel.

Crohn's disease affects men and women equally.

Researchers believe that Crohn’s runs in some families, and also in both genders. Up to 20% of people with Crohn’s have a blood relative with some form of IBD.1

Crohn’s disease can occur in people of all age groups, but it’s more often diagnosed in people between the ages of 15 and 35.1

Did you know?

Crohn's may involve inflammation of all layers of the intestinal wall.

On the other hand, UC
only affects the
innermost lining of the large intestine.
