What is a colonoscopy screening for, and how often will I need to have one?
A colonoscopy is a test that lets your doctor look inside your large intestine.
A colonoscopy is one of the tests doctors use to diagnose ulcerative colitis — a condition that causes swelling and sores in the lining of the rectum and colon. By looking directly at that lining, your doctor can see changes that other tests may not show. How often you need a colonoscopy is an individual decision. Talk with your care team about the schedule that is right for you.
