For the procedure itself, you'll lay on your side, and once the sedation takes effect, you won't remember much else. While you are sedated, the doctor will insert a long, hose-like instrument called a colonoscope into your anus and through the natural cavity of your rectum and colon. The colonoscope is fitted with a light, a camera, and other instruments that the doctor will use to examine your colon for:
Inflammation (swelling and/or redness)
Polyps (growths that appear on the surface of the colon)
Precancerous lesions and potential cancer
Other signs of digestive problems
The procedure also allows the doctor to remove polyps before they become cancerous and take other small samples, or biopsies, for lab analysis. Remember that there are no nerve endings in the lining of the colon. Biopsies and polyp removal should be a relatively painless process. If you have any questions about your procedure, contact your healthcare provider.
After the procedure
After the colonoscopy, you will be taken to a recovery room where you can rest until the sedation partially wears off. Once you are awake, your healthcare provider will speak to you about the results of the colonoscopy. Any polyps or other lesions that are removed or biopsied will be sent to a lab for analysis.
You may feel some bloating from the procedure and pass some gas. These symptoms should subside within a few hours.
Don't plan on driving or operating any machinery until after you've had a
full night's sleep.
