Before the test, a doctor will review the procedure with you, including possible complications, and will ask you to sign a consent form. You will be given fluid and medicines through the IV line. With sedation/analgesia provided by the anaesthetist so you fall sleep for the duration of the procedure while you are being closely monitored.
The colonoscope is a flexible tube with a fibre optic camera, approximately the diameter of the index finger. The scope gently pumps carbon dioxide into the colon to inflate it and allow the doctor to see the entire lining. You might feel bloating or gas cramps as the carbon dioxide opens the colon. Try not to be embarrassed about passing this gas post procedure and let us know if you are uncomfortable.
During the procedure, we may take a biopsy (small pieces of tissue) or remove polyps. Polyps are growths of tissue that can range in size from the tip of a pen to several inches. Most polyps are benign (not cancerous). However, some polyps can become cancerous if allowed to grow for a long time. Having a polyp removed does not hurt.

The Laxative bowel preparation usually induces frequent, loose bowel movements within 1 to 3 hours of taking the first dose. It is best to stay at home in the afternoon within easy reach of toilet facilities. To avoid dehydration and to gain an ideal bowel preparation and procedure outcome, please ensure that you consume a large amount of water and fluids in addition to that consumed with the bowel prep.
Make sure that you have plenty of water and approved clear fluids before and after each dose of Ducolax.
Hint: The PICOPREP and GLYOCPREP are best consumed cold and through a straw. You may choose to place a “Werther’s Original” or similar type lozenge in your mouth whilst drinking.
You can take most prescription and non-prescription medicines right up to the day of the colonoscopy. Dr Yoganathan should tell you what medicines to stop. You should also tell the doctor if you are allergic to any medicines.
Some medicines increase the risk of heavy bleeding if you have a polyp removed during the colonoscopy. Ask your doctor how and when to stop these medicines, including warfarin / Coumadin, Clopidogrel / Plavix, or any other anticoagulant medicine. Do not stop these medications without first talking with your doctor.
After the colonoscopy, you will be observed in a recovery area until the effects of the sedative medication wear off. The most common complaint after colonoscopy is a feeling of bloating and gas cramps. You may also feel groggy from the sedation medications. You should not return to work or drive that day so be sure to organise transportation home. Most people are able to eat normally after the test. Ask your doctor when it is safe to restart your blood-thinning medications.
Although many people worry about being uncomfortable during a colonoscopy, most people tolerate it very well and feel fine afterward. It is normal to feel tired following the procedure so plan to take it easy and relax the rest of the day. We will describe the results of the colonoscopy as soon as it is over.
Most patients are given a sedative (a medicine to help you relax) during the colonoscopy, so you will need someone to take you home after your test. Although you will be awake by the time you go home, the sedative / anaesthetic medicines cause changes in reflexes and judgment that can interfere with your ability to make decisions, similar to the effect of alcohol. You will not be able to drive home or go back to work after the examination if you received sedation for the procedure. You should be able to return to work the next day.
Colonoscopy is a safe procedure, and complications are rare but can occur:
