Safe bowel cleansing before colonoscopy in patients with heart, kidney, or liver disease

This study is testing whether a specific bowel-cleansing solution called PEG (polyethylene glycol) is safe to use in patients with chronic heart disease, chronic kidney disease, or chronic liver disease who need a colonoscopy. Normally, doctors use larger doses of this cleansing solution, but this trial is investigating whether a smaller dose works just as well while being safer for people with these underlying health conditions. The goal is to make sure the procedure goes smoothly without causing complications.

People with chronic heart, kidney, or liver disease face extra risks during colonoscopies because their bodies may not handle the standard bowel-cleansing solution well. This trial aims to find out if using a smaller dose of this medication can be both effective and safe for these vulnerable patients.
