A colonoscopy is the visual examination of the colon (large intestine) using a lighted, flexible video endoscope. This flexible colonoscope is a remarkable piece of equipment that can be guided around the bends in the colon. The colon is approximately 5-6 feet long (condensed into our abdominal cavity) and looks similar to a big question mark.

There are several reasons why a colonoscopy is performed. These could include but are not limited to: bleeding, abdominal pain, diarrhea, anemia, colitis, abnormal CAT scans, history of polyps, or a history of colon cancer (self or family).  Screening is recommended for everyone starting at age 50 or sooner if there is a family history of colon cancer.

To allow for the physician to adequately see your colon, you will be asked to take a laxative and follow a clear liquid diet only (NO FOOD) the day prior to your procedure. Please see the prep/laxative link below for additional information and recommendations for the laxative prescribed for you.

Our staff will attempt to call you a minimum of 2 business days before your procedure. The call will take approximately 20 minutes. Please be prepared with the following information:

·         Medical information that details your own history including surgeries.

·         Complete list of mediation and dosages you currently take. Include all prescriptions, over-the-counter medications and any other natural or organic drugs.

·         List of allergies.

It is very important that we gather this information Prior to the day of your procedure. Below, you will find some FAQ’s that you may find helpful. You should have also received a white envelope from Consultants in Gastroenterology which should contain a pamphlet explaining the procedure. If you do not hear from us, you may contact us at 402-484-9050.
