Colonoscopy - A Diagnostic Procedure
Colonoscopy is a diagnostic and/or therapeutic procedure that examines a patient’s rectum and large intestine. The entire colon is examined using a lighted flexible tube that is inserted into the anus and advanced through the colon to the cecum (junction of the colon and small intestine). This exam is used in the diagnosis of colon cancer, colon polyps, inflammatory bowel diseases (Ulcerative Colitis and Crohn’s Disease), hemorrhoids, diverticulosis and other issues related to the colon.
We recommend that both men and women begin receiving a colonoscopy every 10 years at the age of 50. However, those with a higher risk, such as a family history of colon cancer or colon polyps, may be urged to begin having a colonoscopy from an earlier age and more frequently.
How to Prepare for Colonoscopy
- Our office will give you instructions as to which bowel preparation you will need to clean out your colon. You may also have diet and/or medication restrictions the week prior to the procedure. Please consume the entire preparation that you have been prescribed.
- If you have not received the instructions on how to prep for a colonoscopy two weeks prior to the exam, please contact us.
- Plan to take the day off from work for the procedure.

- Our staff will attempt to contact you the day prior to your procedure to answer any questions you may have.
- We recommend that you avoid eating seeds, nuts, and corn for one week prior to the procedure.
