Ulcerative colitis

Ulcerative colitis makes swelling, inflammation, and sores in the lining of the large intestine (colon) and causes diarrhea, belly pain, and bleeding from the rectum. It's a lifelong condition, but in most people the symptoms come and go.

Medicines can stop or reduce symptoms and prevent flare-ups. If the disease is severe, you may need surgery to remove the colon.
