What is Crohn Disease?
Crohn's disease is a type of inflammatory bowel disease where the lining of the large intestine and the rectum is affected with chronic inflammation and sores, or ulcers.
This damages the intestines and can lead to reduced absorption of nutrients (malabsorption).
This disease causes attacks of bloody diarrhea that can come and go.
Crohn's disease can affect any portion of the gastrointestinal tract from the mouth to the anus, but it most commonly involves the lowest portion of the small intestine (the ileum).
The cause of Crohn's disease is not known, but may run in families. It may occur at any age, but is rare before the age of 7 and is most commonly seen in young adults between the ages of 20 and 30.
Crohn's disease is more common in people who are Jewish and less common in African Americans.
