Assessment of Safety, Quality, and Acceptance of a Bowel Preparation Using a Food Kit With Laxatives
A Single-Center, Randomized, Prospective, Single-Blinded Study to Assess the Safety, Quality, and Tolerance of a Bowel Preparation Using a Food Kit With Laxatives in a United States Veteran Population
The main purpose of this research study is to learn if an alternative bowel preparation (bowel prep) for colonoscopy is safe, tolerable and effective as compared to the standard bowel prep.
Participants are randomly assigned to receive one of the following bowel cleansing regimens for colonoscopy.
- Standard Bowel Prep which includes a clear liquid diet the day before the scheduled procedure and two doses of a laxative, polyethylene glycol 3350 (PEG-3350) taken with 4 liters of water.
- Happy Colon Foods Bowel Prep which begins the day before the scheduled procedure and contains various low residue foods (foods that are easily digested and absorbed), and seven doses of laxatives including PEG-3350 taken with a total of about 4 liters of water, senna tablets, and one dose of magnesium citrate.
