How can I make my colonoscopy preparation more effective?

This question was asked in Airmont, New York on 06/19/2012.
During my first colonoscopy, I was not cleaned out completely from the colon prep. I used Suprep. I followed the directions, but it did not work. The endoscopy was fine. The results were also fine. How many people have this problem? What’s to guarantee that it will work this time? Is this common? I do not eat right and am always constipated. I seem to be better now and have been eating a lot of fiber. How many people have repeat colonoscopies for the same reason?

My recommendation is to stay on clear liquids for 2 days before and use some kind of prep both 2 days before and split dosing the day before and the morning of. This should be discussed with your gastroenterologist.
