Overview

Crohn's Disease

Crohn's disease is a type of inflammatory bowel disease (IBD). It can cause inflammation along any part of the digestive tract – from the mouth to the anus – but most commonly affects the last part of the small intestine, called the ileum, and the large intestine, including the rectum. It's considered a chronic condition because it may recur throughout a person's lifetime, with periods that are free of symptoms. Unfortunately, there is no way to predict when symptoms will return.

Most people with Crohn's disease are diagnosed before the age of 30, although the condition can occur in young children and in adults well past middle age. Men and women are equally affected, and people living in northern climates have a higher incidence. The condition can be inherited and is common in some families. About 12 percent of people with Crohn's disease have a close relative who also has the disease or has the other main type of IBD, ulcerative colitis. The cause of Crohn's disease is unknown. However, the primary trigger of the disease is believed to be the immune system's response to certain viruses and bacteria, leading to intestinal inflammation.
