NCT01454388

Brief Summary

In addition to bowel cleansing agents, the current practice of bowel preparation for colonoscopy involves a low residue diet 48 hours prior to and a clear fluid diet the day before the procedure. This study aims to test whether patients who consume a low residue breakfast the day prior to colonoscopy have a difference in the quality of their bowel preparation. Patients requiring outpatient colonoscopies will be asked to participate. They will be randomized to either breakfast or no breakfast the day before the procedure. Colon cleanliness, patient hunger, and tolerance will be assessed. The investigators hypothesize that there will be no difference in bowel preparation scores and will be better tolerated
