Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) that affects nearly 2 million Americans and millions more worldwide. This chronic condition causes inflammation and ulcers in the colon (large intestine) and rectum, with the immune system mistakenly attacking the lining of these organs. Most people with UC have unpredictable flare-ups that can be challenging to manage, followed by periods of remission with no symptoms. Others never achieve remission.
Ulcerative colitis can greatly affect quality of life, causing fatigue and stress. Severe cases may require surgery to remove the colon.
