Crohn’s disease is an inflammatory bowel disease that causes inflammation and irritation in the lining of the gastrointestinal (GI) tract. It commonly affects the small and large intestine, but can occur at any point from the mouth to the anus. It tends to worsen over time, but periods of remission (where symptoms disappear) may last weeks or years. Though it can develop in anyone at any age, a person is more likely to develop it in their twenties. Additional risk factors include smoking and family history of inflammatory bowel disease.
Crohn’s disease can increase the risk of developing colon cancer, fistulas (abnormal tunnels in the GI tract), abscesses, anal fissures (small tears), intestinal obstructions, and inflammation in other areas of the body.[1]
