What can you eat two days before a colonoscopy? Learn about dietary precautions

If you accidentally develop anorectal diseases in your daily life, you need to go to the hospital for a colonoscopy. There are many issues that need to be paid attention to when doing this kind of examination. You need to pay special attention to your diet a few days before the examination. If you eat something that you shouldn’t eat before the examination, it will have a certain impact on the results of the examination. Especially on the night before the colonoscopy, you must not eat anything. If you have to eat, you should eat some light food or some semi-liquid food to avoid affecting the examination the next day.

1. Eat some food that helps digestion

The day before the colonoscopy, your diet should be light and you should choose foods that aid digestion, such as noodles, porridge, etc. You should drink plenty of water, which will help keep your bowel movements smooth. On the day of colonoscopy, you need to take some bowel-cleansing foods so that the examination can proceed smoothly.

2. Things to note when having a colonoscopy in the morning

Patients who undergo colonoscopy in the morning should pay special attention to their diet at night. They should not eat after 8 o'clock the night before the examination. Friends who like to smoke should also refrain from smoking. They should eat some liquid food for dinner, such as soup, to avoid food accumulation in the intestines.

3. Precautions for afternoon colonoscopy

If the patient is scheduled to have a colonoscopy in the afternoon, he or she can drink some sugar water in the morning of the examination to avoid hypoglycemia, but cannot eat anything else. He or she should also fast at noon and keep the stomach sufficiently empty.

4. Bowel Preparation

Colonoscopy requires intestinal preparation. Patients with poor heart and kidney function should not use castor oil and potassium sodium salt powder. They can drink some warm water to ensure the cleanliness of the intestines.

When doing a colonoscopy, all the feces in the body need to be emptied, so the stomach and intestines are relatively weak during these days. The food you eat should be as easily digestible as possible so as not to burden the intestines. At the same time, you should eat food that is easy to absorb. Various common porridges are better. Eat liquid food for two days.
