A sugar syrup may make colonoscopy prep safer and more effective for diabetics
NCT ID NCT07084350
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial tests whether adding lactulose—a type of sugar syrup—to the standard bowel-cleansing drink (PEG-ELS) can improve colonoscopy preparation in people with type 2 diabetes. Diabetic patients often have poor bowel cleansing, which can reduce the quality of the exam. The study will compare the combination against PEG alone in 300 adults, looking at how well the bowel is cleaned and whether side effects like bloating or nausea are reduced.
