Crohn's disease, also known as ileitis or enteritis, is a type of "inflammatory bowel disease," or "IBD." The disease is characterized by patches of inflammation in the digestive tract. This inflammation causes the intestines to empty more frequently -- resulting in diarrhea. Abdominal pain (or stomach pain) is another common symptom of Crohn's disease. 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. Crohn's disease affects men and women equally and seems to run in some families. It cannot be cured in most people, so it usually requires lifelong treatment. A few things that can help alleviate the symptoms of Crohn's disease include taking medications, making dietary changes, and undergoing surgery.
