You will be provided with clear instructions 5-6 days prior to your procedure. Read these instructions carefully ahead of time. You will need to follow a special diet for a few days before the procedure. You usually start your bowel preparation (often called the bowel prep) the day before the actual test so you may need to change your plans for the preparation day. You will need to stay close to a bathroom as soon as you start the bowel preparation. If any of the instructions are not clear or you do not understand them, call the GIE office and go over them step by step with the staff.
Many people consider the bowel prep the worst part of these tests. Preparation is a critically important part of the procedure. In order for the doctor to see the inside of your rectum and colon clearly, your bowels need to be as cleaned out as possible.
Because colonoscopy is usually done with drugs that make you sleepy, you will miss work the day of the procedure. You might want to schedule the test the day after a scheduled day off, so you can be at home the day before without taking an extra day off.
