Colonoscopy
A colonoscopy is a medical test that lets a doctor look inside your large intestine (also called the colon). The doctor uses a long, thin tube with a light and a camera on the end called a colonoscope to see the inside of your colon. During the test, you will lie on your side on a table while the doctor puts the colonoscope into your rectum (the end of your large intestine). The colonoscope is gently moved through your colon so the doctor can see the inside. The test usually takes about 30 minutes to an hour.
A colonoscopy can help the doctor find problems in the colon, such as polyps (small growths), inflammation, or cancer. The doctor may also be able to treat some problems, like removing a polyp, during the colonoscopy.
Before the test, you may need to follow a special diet and take medicine to clean out your colon. This will help the doctor get a better view during the test. You may also need to take a mild sedative to help you relax during the procedure.
