Test Preparation

Colonoscopy prep is essential to obtaining effective colonoscopy results. The purpose of the prep is to thoroughly clean the colon so gastroenterologists can clearly view the colon to check for polyps.

Polyps come in different shapes and sizes, including flat. Flat polyps can be harder to detect if a colon hasn’t been thoroughly cleansed during the colonoscopy preparation process.

Also, if your colon isn’t completely cleansed, there is a chance that your gastroenterologist could reschedule your colonoscopy. A rescheduled colonoscopy means you will have to go through the colonoscopy preparation process again, and nobody wants to do that.

So to help make your colonoscopy prep a little easier, and to help ensure a successful colonoscopy, below are some colonoscopy prep tips and links to colonoscopy preparation forms.

Colonoscopy Prep Tips

1. Mix and refrigerate the prep solution the day before you start the prep. You want the solution to be very cold.

2. Consider drinking the solution through a straw to minimize the taste.

3. You may mix Crystal Light into the prep solution for flavoring. You may not put Crystal Light in Suprep as it is already flavored.

4. Use flushable wet wipes instead of dry toilet paper.

5. Have some Tucks pads, A&D Ointment, or Preparation H available to soothe a sore bottom. Use products as needed for irritation.

6. Use A&D Ointment before and after each bowel movement.

7. Stay close to toilet facilities once you have started your colon prep.

8. Gummy bears dissolve to a clear liquid at body temperature, so they are okay to take with your prep and give you something to eat. No red gummy bears.

9. Drink as much clear liquids as possible during the prep. It will keep you hydrated and ensure that your colon gets cleaned out.

10. Prepare your favorite Jell-O flavors in quantity. Have popsicles, chicken and beef broth, white grape juice, and sports drinks on hand in large quantities. No red or purple flavors.

11. Pat dry, do not rub.

12. Consider taking some reading material into the bathroom and staying a while instead of running back and forth.
