Notes for colonoscopy

1. Diet adjustment: Patients should adjust their diet in a timely manner a few days before the examination, and try to use light, digestible liquid or semi-liquid food.2

. Clean the intestinal tract: Patients should pay attention to fasting on the day of examination, and use lactulose, magnesium sulfate, mannitol and other drugs to clean the intestinal tract under the guidance of doctors, so as to facilitate the smooth progress of colonoscopy.

3. Bed rest: Patients who take intestinal biopsy should absolutely rest in bed after the examination, and pay attention to observing the color characteristics of feces to prevent intestinal bleeding.
