What Is A Colonoscopy?

Diagram of the Colon/Colonoscopy

A Colonoscopy is an exam to evaluate your entire colon. In this exam, your colon is cleansed. A long fiberoptic tube is inserted through your rectum and into your colon. The fiberoptic scope (endoscope) is a long bundle of enclosed and very flexible fibers. These fibers transmit light to the area examined and send images from that area to your caregiver. Discomfort is usually minimal. You will be given a drug to help you sleep (sedative) during the procedure. This exam helps to detect tumors (cancers), polyps (colonic growths), inflammation (colitis), areas of bleeding (such as Diverticulosis), and other colonic abnormalities. Your doctor may also take a small piece of tissue (biopsy) that will be examined in a lab under a microscope.


Before The Procedure:


  • A clear fluid diet is required for 24 hours before the exam
  • A special electrolyte solution will be given to you to drink over a short period of time. This solution is used to clean out your colon
  • Laxatives will also be required
  • You must drink plenty of fluids all day before your exam

After The Procedure:


  • Even though you did not have a general anesthetic, you have received sedation. Get plenty of rest for 24 hours after your examination. We suggest a light diet for the remainder of the day
  • You may experience some cramping, gas, bloating, or a “full feeling”. You will pass the gas over the next few hours
  • You must NOT drive on the day of the procedure. Please arrange for someone to drive you home after the exam
  • Follow your doctor’s specific instructions concerning treatment and follow-up care. Contact us if you have any questions

For 24 hours after the examination Do Not:


  • Drive a motor vehicle
  • Operate machinery
  • Drink alcohol

Notify your doctor immediately or go to the nearest Emergency Room if you experience any of the following:


  • Severe or persistent abdominal pain
  • Fever and/or vomiting
  • Persistent or large amounts of blood in your stool


Note: A small amount of rectal bleeding may be normal, especially following polypectomy or hemorrhoid treatment.
