There is no known cause, although it may be hereditary. The symptoms include intermittent attacks of diarrhea and abdominal pain, weight loss, and fever. Rarely, the intestine may become blocked or ulcerate into adjacent areas via fistulas.
Treatment involves a nutritious diet, painkilling drugs, antibiotics, and sometimes corticosteroids.
If complications occur, the physician may recommend surgery to remove the diseased section of intestine, though the inflammation has a tendency to recur.
