Crohn's disease is a lifelong disease that causes swelling, inflammation, and deep sores in the lining of your digestive tract. It usually affects the small and large intestine. But it can attack any part of the digestive tract, from the mouth to the anus.
Crohn's may run in families. It can cause diarrhea, belly pain, and weight loss. Medicines can help control inflammation and keep the disease from causing symptoms.
