Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is a diagnostic procedure that examines the lining of your large intestine, also called the colon, to look for signs of abnormalities. 

During the procedure, your provider inserts a thin, flexible tube with a light and camera (colonoscope) into your anus and then slowly advances the tube into your rectum and throughout the entire length of your colon. 

The colonoscope transmits images of your large intestine on a computer screen, allowing your provider to examine the tissue. 

Why would I need a colonoscopy?

There are many reasons you may need a colonoscopy. Your primary care doctor may recommend you undergo a colonoscopy to screen for colon cancer. 

Starting at age 50, everyone should have a colon cancer screening. Though there are several colon cancer screening options, a colonoscopy is the most comprehensive. 

You may also need a colonoscopy to find the cause of your gastrointestinal symptoms, such as abdominal pain, chronic constipation or diarrhea, or rectal bleeding. 

How do I prepare for a colonoscopy?

The team at Timothy W. Teslow, M.D., P.C. provides specific instructions on bowel preparation for your colonoscopy. In order for the team to get the most accurate results from your colonoscopy, your colon must be completely clean.

Generally, the team requires that you follow a clear liquid diet the day before your colonoscopy and take a colon-cleansing medication (laxative). Then you must stop everything, the clear liquids and even water, for the eight hours prior to your colonoscopy.

What happens during a colonoscopy?

To help you relax and ease discomfort during your colonoscopy, your surgeon may provide a mild sedative prior to the procedure.

During your colonoscopy, you lie on your side on the exam table and your provider inserts the colonoscope in your anus and slowly advances it through your large intestine. You may feel some pressure, bloating, or cramping during the procedure. 

If your provider finds any polyps (noncancerous growths) during your procedure, they burn or remove them. They also take samples of any other tissue abnormalities to send out for testing. 

Your colonoscopy may take 30-60 minutes. Afterward, the team sends you to the recovery area for monitoring and reviews the results of the procedure with you. You need to have someone drive you home after your colonoscopy, and you should take it easy the rest of the day.
