You are about to have a colonoscopy. This test involves examining the inside of your colon and rectum with a camera. The procedure takes about 15 to 20 minutes. After the test, the nursing staff will keep you under observation for about 30 to 60 minutes. You should expect the appointment to take about 2 hours in total.
A colonoscopy is done to:
- Take biopsies or remove polyps;
- Control bleeding in the colon;
- Make a diagnosis.
