c) For good bowel preparation, it is recommended that you drink as much water as you can to help empty your bowels.

Patients who have made an appointment for colonoscopy are advised to avoid foods with high fiber content (fruits, vegetables, whole grains) from 3 days in advance, and choose low-residue meals (porridge, porridge, noodles, bread, steamed eggs, egg drop soup, tofu, minced and boiled lean meat or fish). Choose clear liquid (rice soup, soy milk, lotus root powder, fruit juice, vegetable juice) for dinner 1 day before the examination, and do not drink milk!

2. When you can't eat.

Do not eat by mouth for 6-8 hours before colonoscopy! Do not drink any liquids (including water) 2 hours before the test!

3. Oral laxatives to cleanse the intestines.

At present, the most widely used oral intestinal cleansers include compound polyethylene glycol electrolyte powder and mannitol injection. The day before the examination can be given orally 1 hour after dinner (around 8 p.m.), or if the examination is scheduled in the afternoon, it can be taken orally after waking up early on the day of the examination, at least 6-8 hours before the examination time. If you take it at a rate of about hour, the feeling of bloating will come as expected after about 1 hour, so remember to choose a convenient place to go to the toilet in advance.

If you feel unbearable bloating or abdominal pain, you can temporarily slow down the speed of taking or pause the dose, and wait for the symptoms to disappear before resuming the dose. If you feel that the taste is not good, you can let warm water cool or drink it through a straw, which may be easier to take.

Most people can become "watery" after 3-4 bowel movements, and for people with constipation, more bowel movements may be required to reach the goal. Poor bowel preparation may be detrimental to a colonoscopy, and a more comprehensive bowel cleansing, such as a clean enema, will have to be attempted. Therefore, try to strictly follow the guidance to prepare, and strive to be in place at the first time.

If bowel preparation is still poor, it is recommended to consume clear liquids 2 days in advance, consider taking laxatives for 2 consecutive days, and schedule colonoscopy for the morning. Don't drink too much or too fast in order to meet the test standards as soon as possible, or change the medicine yourself!

The first point is not to eat, if you eat, you will definitely not be able to do this gastroscopy, the second point is that the mood must be adjusted, don't be too nervous, in fact, doing gastrointestinal endoscopy is a very simple process, the third point is that you should urinate first, so that you can do gastrointestinal endoscopy, and there will be no mistakes in the middle.
