What to Expect in Colonoscopy Prep

A colonoscopy refers to the insertion of a thin tube with a tiny camera into the rectum and the large intestine for the purpose of viewing its walls. This procedure is done to find any abnormalities such as polyps, ulcers and tumors that may be cancerous. Preparing for a colonscopy involves fasting, eating a special diet and taking a very powerful laxative.

The primary task before the colonoscopy is evacuation of the colon. All waste must be cleared out, or the procedure will be useless and done again. Your doctor will be looking at your colon, and if it is not clean, won't be able to see anything. The most important thing is to follow the doctor's instructions.

About Diet

Physicians typically order a special diet for colonscopy preparation, generally one that is clear liquids only; no solid foods are permitted for 24-72 hours before the procedure. Clear liquids include: chicken broth, gelatin and popsicles. Coffee or tea with no cream or milk. Fluids containing blue, purple and red coloring should be avoided.

Cleansing Your Bowel

A variety of bowel-cleansing preparations are prescribed to patients preparing for a colonoscopy. These range in the way they work. Some push water out of the colon, taking waste out along with it, while others pull water into the colon. These can be taken as a liquid or tablets.

Set-Up Shop in the Bathroom

Substances taken for colonscopy prep are powerful--they cause diarrhea. Wear clothing that is non-constricting and easy to remove. Have your favorite music and books nearby. Due to all of the wiping you'll be doing, you can get chaffed and it can hurt. Use adult wipes like Tucks and use a petroleum-based product to protect your skin in that area, such as Vitamin A and D Ointment or Vaseline.
