A colonoscopy is a procedure to look in the colon for anything abnormal.

It is VERY important that your colon is cleared of all stool before your colonoscopy. This will allow your doctor to see the lining of your colon and look for any abnormalities, like polyps or growths. To clean your colon; you must:

  • follow a special diet the whole day before your test
  • take the prescribed bowel prep medication that you will get from your pharmacy

  • lemon-lime or ginger ale sodas
  • gelatin (NOT red or purple)
  • apple juice
  • ice popsicles (NOT red or purple)
  • white grape juice
  • coffee or tea (NO creamer or milk)
