Colonoscopy Overview and Additional Procedure Information

A colonoscopy is a day-case procedure in which the inside of the large intestine (colon and rectum) is examined. A colonoscopy is commonly used to evaluate gastrointestinal symptoms, such as rectal and intestinal bleeding, or changes in bowel habit. Colonoscopy is also advised in individuals without symptoms to check for colorectal polyps or cancer. A screening colonoscopy is recommended for anyone aged 45 years or older, and persons with a family history of colon polyps or cancer should be screened at an age 10 years younger than it was diagnosed in the family member.
