Colonoscopy 101: What to expect?

First of all, what is a colonoscopy?

A colonoscopy or coloscopy is the endoscopic examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus.

When should you schedule a colonoscopy?

Colon cancer screening should begin at age 45 for most people. If a colonoscopy doesn’t find adenomas or cancer and you don’t have risk factors, the next test should be in ten years. If one or two small, low-risk adenomas are removed, the exam should be repeated in five to ten years.

How long does the procedure last?

The camera sends images to an external monitor so that the doctor can study the inside of your colon. The doctor can also insert instruments through the channel to take tissue samples (biopsies) or remove polyps or other areas of abnormal tissue. A colonoscopy typically takes about 30 to 60 minutes.

Will I have to change my diet before the appointment?

In most cases, patients are advised to stop consuming solid meals about 24 hours before the day of the colonoscopy.
