How to clean the intestines before colonoscopy and pay attention to diet

Colonoscopy is a relatively routine physical examination item. When people have gastrointestinal problems, they may need to undergo a colonoscopy to identify the cause of the disease in order to achieve symptomatic treatment. However, you need to clean your intestines before doing a colonoscopy to avoid affecting the examination results.

1: The day before the examination, you need to eat some easily digestible food, such as porridge, noodles, etc., drink plenty of water, and keep the bowels open. You also need to use bowel cleansing drugs on the same day to keep the intestines clean.

2: Colonoscopy in the morning: Do not eat or drink anything and do not smoke after 8pm the night before. Eat liquid food (rice water, soup) for dinner the day before.

3: Colonoscopy in the afternoon: You can drink some sugar water before 8 am on the same day, but you cannot eat anything else and do not eat at noon. The hospital will prescribe laxatives, and you can take them according to the doctor's instructions.

4: In addition, intestinal preparation is required. Take 30ml of castor oil orally at 8pm the day before the examination (take it in the morning for afternoon examination), take 30g of potassium sodium salt powder at 3am for morning examination (add 6kg of water and take it within 1.5 hours), and take 30g of potassium sodium salt powder at 8am for afternoon examination. It is forbidden for patients with heart and kidney dysfunction.

5: Or fast the night before the examination and take 30ml of castor oil orally at 18:00, and take 250ml of 20% mannitol and 250ml of warm water orally at 5:00 the next morning, and then drink 250ml of warm water every 20 minutes, for a total of 3 times, the effect is better. Or do a cleansing enema once the night before and the next morning. You can drink some warm water.

6: Before doing colonoscopy, it is recommended that you can choose to drink some minced meat porridge, noodles, etc. Remember not to eat vegetables or fruits. Although both of them are easily digestible, they cannot be eaten. When doing intestinal preparation, if you have poor heart and kidney function, castor oil and potassium and sodium salt powder are prohibited. Drink more warm water to keep the intestines clean.

You should start paying attention to what you eat a few days in advance. If you eat something you shouldn’t before the colonoscopy, it will seriously affect the results of the colonoscopy. Especially on the night before colonoscopy, remember not to eat anything.
