A colonoscopy is a procedure in which the inside of the large intestine (colon and rectum) is examined. An instrument called a colonoscope is inserted into the rectum and advanced through the colon, until reaching the cecum (the end of the colon). A colonoscopy is commonly used to evaluate gastrointestinal symptoms, such as rectal and intestinal bleeding, abdominal pain, or changes in bowel habits. Colonoscopies are also performed in individuals without symptoms to check for colorectal polyps or cancer. A screening colonoscopy is recommended for anyone 50 years of age and older, and for anyone with parents, siblings or children with a history of colorectal cancer or polyps.
Your physician will prescribe the necessary preparation for this procedure.
