Colonoscopy: What to Expect

The Procedure

A colonoscopy is a telescopic and visual examination of the bowels using a long thin flexible tube with a lighted camera on the end. The tube is inserted into the rectum and advanced through the colon. The doctor can view the colon lining on a monitor and take biopsies or remove polyps if necessary.

Preparation

To prepare for a colonoscopy, you will need to cleanse your bowels so that the doctor can see the colon lining clearly. This is usually done by drinking a special solution that contains laxatives. You will also need to avoid eating or drinking anything for several hours before the procedure.

Benefits

A colonoscopy can help find and diagnose a number of conditions, including polyps, cancer, and Crohn's disease. The procedure can also be used to remove polyps or tissue samples for biopsy.

Risks

A colonoscopy is a generally safe procedure, but there are some risks associated with the procedure. These include infection, bleeding, and perforation of the colon. The risks are usually small, and the benefits of a colonoscopy usually outweigh the risks.

Recovery

After a colonoscopy, you will be taken to the recovery room where you will be monitored for any complications. You may experience some cramping or bloating, and you may need to rest for a few hours before you can go home. You should avoid driving or operating heavy machinery for the rest of the day.
