Veterans may soon eat real food before colonoscopy
NCT ID NCT07605897
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special food kit with laxatives could make colonoscopy preparation easier and safer for veterans compared to the standard clear-liquid diet. 57 veterans were randomly assigned to either the standard prep or the food kit prep. The goal was to see if the food kit was just as effective at cleaning the colon while being more tolerable and satisfying for patients.
