Bowel Preparation Instructions for Colonoscopy

A good bowel preparation allows your doctor to clearly see the lining of the bowel and thoroughly examine the colon. The procedure is then more likely to be accurate and complete. If the bowel is not completely clean and empty the procedure may need to be postponed or repeated. Potential complications may also occur, or potential cancer lesions could be missed.

You will be instructed to use either PicoPrep or Glycoprep-C by Dr Jamnagerwalla before your colonoscopy. These may be purchased from our Practice or from any chemist without a prescription.

The following instructions should be followed to ensure your colon is clean for a successful colonoscopy.

Two days before your colonoscopy, commence a low residue diet (see the table below). You may also eat eggs, cottage cheese, plain yoghurt, fish and chicken. Ensure you drink plenty of clear liquids.
