How to Prepare for a Colonoscopy?

The colon must be completely empty for a colonoscopy. Different physicians have different methods, but usually two days before the procedure you will need to take a laxative or two. For two days before, you will only be allowed to drink clear liquids and take laxatives based on a schedule provided to you by your physician. It isn’t easy, but worth doing right. If the colon isn’t clear, the test will have to be repeated at another time.
