Preparing for a colonoscopyHow to Prepare for a Colonoscopy

Preparing for a colonoscopyWhen preparing for a colonoscopy, it’s very important to follow all of directions carefully. You will receive a packet of information at your initial consultation at Digestive Care Physicians with locations in Alpharetta, Cumming, Johns Creek and Lawrenceville, Georgia. In your packet you will find prep instructions.

Your colon has to be empty and clean for your doctor to get  a proper look at it. To make that happen, you’ll have to fast and use strong laxatives beforehand. You’ll be given a prescription for the type of laxative to use and instructions for times to drink along with the amount of water you should drink with the laxative. While in may be inconvenient and somewhat unpleasant, it’s necessary for getting correct results that could save your life.
