Q:

How do you perform a colonoscopy prep?

A:

Quick Answer

To perform a colonoscopy prep, start a low-fiber diet a few days before the procedure transitioning to no solid foods the day before the colonoscopy, and then drink a bowel-cleaning preparation, which empties your colon. Your doctor may advise you to finish the prep the day before the colonoscopy or split it between the day before and the day of the procedure, according to Harvard Health Publications.

Your low-fiber diet before the colonoscopy should include no whole grains, nuts, seeds, dried fruit, or raw fruits or vegetables. The non-solid food diet after that can include clear broth or bouillon, black coffee or tea, clear juice, clear sports drinks or soft drinks, Jell-O and Popsicles. Avoid eating or drinking anything two hours before the procedure, states Harvard Health Publications.

To make the bowel-cleaning preparation easier to drink, add some Crystal Light or Kool-Aid powder to it, but do not mix anything with it that contains red, blue or purple dye. Other tips are to add some ginger or lime, drink it chilled or drink it through a straw. Sucking on lemons or holding one near your nose as you drink may help, reports Harvard Health Publications. Some people favor drinking the liquid as fast as they can, while others prefer to take it more slowly.
