Colonoscopy is a procedure that lets Double Check’s experts look at the inner lining of your large intestine (rectum and colon). A thin, flexible tube called a colonoscope is used to look at the colon. A colonoscopy helps find ulcers, colon polyps, tumors, and areas of inflammation or bleeding. It also lets the physician take some tissue for testing, or to prevent further tissue growth.
The colon must be free of solid matter for the test to be performed properly. The patient follows a low-fibre diet for the 3 days leading up to the colonoscopy and is given a laxative to drink the day before the procedure.
