What Is a Colonoscopy?

Colonoscopy is an outpatient procedure that examines your large bowel (colon and rectum). Colonoscopies are usually used to evaluate symptoms like abdominal pain, rectal bleeding, or changes in bowel habits. They are also used to screen for colorectal cancer in individuals, typically once a person turns 50 years old.

How Is a Colonoscopy Performed?

A colonoscopy lasts approximately 30-60 minutes. Medications will be administered to make you feel relaxed and drowsy. You will be asked to lie on your left side on the examining table. During a colonoscopy, the doctor uses a colonoscope, a long, flexible, tubular instrument about 1/2 inch in diameter that transmits an image of the lining of the colon so the doctor can examine it for any abnormalities.

During the colonoscopy, if the doctor sees something that may be abnormal, small amounts of tissue can be removed for analysis and abnormal growths, or polyps, can be identified and removed. In many cases, colonoscopy allows accurate diagnosis and treatment without the need for a major operation.
