Crohn disease is a severe, chronic inflammatory bowel disease. It causes inflammation,
ulcers, and bleeding in the digestive tract. It usually affects the end portion of the small intestine called the ileum. However, any part of the digestive tract can be affected, from the mouth to the anus.
The cause of Crohn disease is not known.
Inflammatory bowel diseases
and Crohn disease, tend to run in some families. Some researchers think that it is due to a reaction to a virus or bacteria that causes the immune system to overreact and damage the intestines.
Very severe Crohn may not improve with medications. You may be advised to have the diseased section of your intestine removed. The two remaining healthier ends of the intestine are then joined together. You are still at high risk for the disease returning.
Surgery may also be done if you have an obstruction or fistulas.
