Crohn’s disease is a long-term condition in which there is inflammation of the intestine, most commonly the last part of the small intestine (ileum) or colon. The cause is unknown, but it is thought to be due to an immune system problem.
Symptoms tend to occur intermittently. During an attack, they may include diarrhea, abdominal pain, fever, and weight loss. There may also sometimes be bloody diarrhea, bleeding from the rectum, joint pain, inflamed eyes, and a rash. Possible complications include intestinal obstruction and malabsorption.
Treatment is usually with medication to reduce inflammation and alleviate symptoms. In some cases, surgery to remove affected parts of the intestine may be needed
