Before a colonoscopy, it is important to follow the instructions provided by your doctor or medical center. Here are some general steps that may be included in the preparation process:
-
Plan ahead: Clear your schedule for the evening before and the day of your colonoscopy, and make plans for someone to go with you the day of the colonoscopy. Shop for some key supplies several days ahead, too.
-
Diet: Follow a low-fiber diet for three days before the procedure. On the day before the colonoscopy, you should only consume clear liquids, such as sports drinks, clear juice like apple and white grape, and clear broth. Soda is OK, and so are coffee and tea, but without cream. You can have gelatin and ice pops, but stay away from anything colored red, blue, or purple. The dyes can discolor the lining of the colon and make it harder for the doctor to see.
-
Medications: You can take most prescription and non-prescription medications right up to the day of the colonoscopy. However, stop medications that are for diarrhea (Imodium, kaopectate) or contain iron 7 days prior to your procedure. Low-dose aspirin can be continued and does not need to be stopped prior to your colonoscopy. Insulin/diabetes medication doses may need to be adjusted. Consult your prescribing doctor. Blood-pressure medicines should be continued while preparing for the colonoscopy.
-
Laxative: You will be given a prescription or over-the-counter laxative specified by your doctor. You will drink half of the laxative drink the evening before the procedure and finish it the next morning. You will develop significant diarrhea after drinking the preparation. Plan to be near a bathroom.
-
Transportation: Arrange for someone to drive you home after the colonoscopy. Do not use alcohol, marijuana, or other substances that could impair your thought process prior to your appointment. Do not drink alcohol, drive a car, or sign legal documents until the day after your procedure.
It is important to follow these steps carefully to ensure that your colon is empty and clean for the procedure. If you have any questions or concerns, be sure to contact your doctor or medical center for guidance.
