Colonoscopy Preparation Instructions
A successful colonoscopy starts with a successful bowel preparation.
Inadequate prep is associated with lower polyp detection rate and repeating the procedure at a shorter interval due to low visibility. A clean bowel will ensure the endoscopist can clearly see and remove polyps in your colon. Please review our step by step instructions below:
