The day before colonoscopy

Doctors usually tell patients to empty their intestines the day before a colonoscopy, because this can make the colonoscopy more effective. Only patients with more serious gastrointestinal diseases need colonoscopy, and the price of colonoscopy is relatively expensive. Some doctors even recommend patients to take laxatives to clean their intestines. So what do you need to prepare the day before a colonoscopy?

Colonoscopy requires emptying the intestines in advance, and laxatives are needed to clean out the accumulated feces in the intestines so that during the examination, it is possible to clearly see whether there are any lesions in the intestinal mucosa. This preparation work to empty the intestines needs to be done in advance. You need to eat some liquid, easily digestible food the day before the colonoscopy. Avoid eating hard or residue-containing food.

You need to take laxatives 10 hours before colonoscopy. At present, it is necessary to empty the intestines more than twice and take laxatives more than twice. Drink a laxative once 10 hours in advance and a second laxative 6 to 8 hours in advance. Keep drinking until the water excreted from the intestines is basically clear. This means that the intestines are ready before colonoscopy.

It is best not to eat the day before a colonoscopy. Patients with gastrointestinal diseases should fast the day before a colonoscopy in order to clean the intestines. If the intestines are not cleaned, the doctor will not be able to perform a colon examination smoothly. In order to clearly observe the specific conditions of the intestines, patients with gastrointestinal diseases should prepare their intestines and expel the feces in the intestines. Common preparations before the inspection are as follows:

About two days before the colonoscopy, pay attention to eating some pasta, rice porridge and other foods low in fiber to reduce the chance of fiber forming stool in the intestines. The day before the colonoscopy, the patient needs to take laxatives orally to further empty the feces in the intestines. Generally, when the feces are clear water-like, it means that the intestines have been cleaned.

Some necessary tests need to be done before colonoscopy. Before colonoscopy, patients need to have blood drawn for testing to check routine blood indicators. During colonoscopy, there is a high probability of damaging the intestinal mucosa, which may cause intestinal bleeding. If you are taking oral antiplatelet drugs, you need to stop taking the relevant drugs one week before the colonoscopy.

After the colonoscopy, the patient can eat some light and easily digestible food, and avoid spicy, raw, cold and irritating food, so as not to further irritate the gastric mucosa. Never overeat, and always eat small and frequent meals.

In order to ensure the scientific accuracy of colonoscopy data, gastrointestinal patients should eliminate tension, maintain a normal mentality, and reduce the secretion of gastric juice and gastric peristalsis to make the examination image clearer. If necessary, gastrointestinal patients can use sedatives and other drugs before the examination to relieve tension. Patients should cooperate with the doctor's examination.
