Patient's question:
NoDoctor's answer:
Hello, you cannot have a colonoscopy on the day of the examination. On the day before the test, have a half-liquid, low-fiber diet such as congee, and avoid vegetables and seeded fruits like watermelon. About 4 hours before the test, adults should take 50 grams of magnesium sulfate powder mixed with 100 milliliters of warm water orally, and children should take 25-35 grams. After that, drink 2000-2500 milliliters of warm water within 1 hour. It usually takes about half an hour to start having bowel movements, and having 5-7 bowel movements can basically clear the feces from the colon.
