Diet
A few days before the colonoscopy procedure — Start a eating a low-fiber: no whole grains, nuts, seeds, dried fruit, or raw fruits or vegetables.
The day before the colonoscopy procedure — Don’t eat solid foods. Instead, consume only clear liquids like clear broth or bouillon, black coffee or tea, clear juice (apple, white grape), clear soft drinks or sports drinks, Jell-O, popsicles, etc.
The day of the colonoscopy procedure — As on the previous day, clear liquid foods only. Don’t eat or drink anything two hours before the procedure.
Make sure you receive your colonoscopy prep instructions well before your procedure date, and read them completely as soon as you get them. This is the time to call your clinician with any questions and to buy the bowel prep she or he has prescribed. Pick up some medicated wipes (for example, Tucks or adult wet wipes with aloe and vitamin E) and a skin-soothing product such as Vaseline or Desitin — you’re going to be experiencing high-volume, high-velocity diarrhea.
Arrange for the time and privacy you need to complete the prep with as little stress as possible. Clear your schedule, and be at home on time to start your prep. If you have children or aging parents who need attention, have someone else be available to them while you’re indisposed.
Water can get boring, so keep a variety of clear liquids on hand. On the day before your colonoscopy — when you’re restricted to clear liquids — you can have popsicles, Jell-O, clear broth, coffee or tea (without milk or creamer), soft drinks, Italian ice, or Gatorade. But take nothing with red, blue, or purple dye. Drink extra liquids before, during, and after your bowel prep (usually until a few hours before your procedure), as well as after your colonoscopy.
To make a bad-tasting liquid prep like magnesium citrate easier to swallow, try one or more of the following if it doesn’t come flavored: add some Crystal Light or Kool-Aid powder (again, not red, blue, or purple); add some ginger or lime; drink it chilled; drink it through a straw placed far back on your tongue; hold your nose and drink it as quickly as possible; quickly suck on a lemon slice after you finish each glass; hold a lemon or lime under your nose while you drink; suck on a hard candy after each glass.
Wear loose clothing, and stay near the bathroom. Better yet, once the preparation starts to work, stay in the bathroom — because when the urge hits, it’s hard to hold back. Consider setting up shop near the toilet with music, your laptop, magazines, or books.
