Crohn's Disease – Harvard Medical School

Crohn’s disease is an inflammatory bowel disease. It causes damage in the digestive tract, most often in the small and large intestines. People
with Crohn’s disease experience diarrhea, abdominal pain, weight loss, and fatigue. Crohn’s disease may cause only occasional symptoms. Or the
symptoms may be constant. Medications can usually control the inflammation. But sometimes surgery is required.
