Summary

This study tests whether mixing an electrolyte beverage with water improves the quality and tolerability of bowel preparation before colonoscopy. 405 adults scheduled for colonoscopy will be randomly assigned to drink polyethylene glycol (PEG) with water only, or with a low or medium amount of electrolyte drink. The goal is to see if the electrolyte mix helps people drink the full preparation and improves bowel cleanliness.
