Preparations for Endoscopy and colonoscopy preparations

Colonoscopy preparation form:

Performing an accurate colonoscopy depends on the cleanliness of the colon, and the cleanliness of the colon depends on the strict compliance with the conditions of the present instructions and the maximum use of fluids during the hours of preparation and walking.

A colonoscopy exam allows your doctor to see the inside of your large intestine (colon) and rectum. It’s one of the most efficient ways for doctors to:

-Look for colon polyps

-Find the source of unusual symptoms

-Detect colon cancer

-What to Eat (and What to Avoid) Before Your Colonoscopy

The main purpose of the bowel preparation before your colonoscopy is to completely empty and cleanse the entire colon. Eating low-fiber foods for several days before your colonoscopy can make the process easier for you while ensuring there are no fiber residues left in the colon. You also will be asked to avoid several types of food and anything that contains red or purple food coloring (natural or artificial).

The patient must be fast 7 hours before the endoscopy.

-Four packets of PEG powder or Pidrolox or Colotrans, one glass every half an hour from 8 am

-Two metoclopramide tablets

-Ten bisacodyl should be taken two times every two hours.

The morning before the colonoscopy, dissolve each packet of powder in 4 glasses of water or simple fruit juice such as peach or apricot and consume one glass continuously every half hour until 5 packets are completed.
