Crohn's disease is characterized by inflammation of the digestive tract. This causes the intestines to empty more frequently, resulting in diarrhea. The condition can occur anywhere along the digestive tract, from the inside of the mouth to the anus, but it is most commonly found near the end of the small intestine and/or colon. Although there is no cure for Crohn's disease, symptoms can be managed by taking medications, making changes to your diet, or undergoing surgery.
