How is a colonoscopy performed?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)

At a colonoscopy, sedating medication will ensure the patient is relaxed. Some doctors will use general anesthesia. The doctor will insert an instrument called a colonocope into the colon to look for polyps, which can be the beginnings of colon cancer. They can be removed right then and there and, if necessary, tested for cancerous tissue later. The entire exam takes about 30 minutes. Drugs may cause the patient to feel groggy, but there is no physical pain.
