Fasting and abstaining from food and water a few days before gastroscopy, who should not have a gast

Doing gastroscopy has no effect on the body, it is certainly not harmful, and doing gastroscopy itself is a means of examination, just like doing electrocardiogram and blood tests, it is an important means to diagnose stomach diseases. If you think it's scary, it's a bit of a fuss. Of course, there will be nausea and other uncomfortable symptoms when doing gastroscopy, but it can be bearable, and it is not as terrible as the legend.

As long as you relax and cooperate with the doctor, I believe it will go well.

1. Before gastroscopy, you must have an empty stomach, at least six hours or more, and do not eat too hard food that is not suitable for digestion before six hours, and try to eat a liquid diet (such as millet soup) or a semi-liquid diet (porridge), if you are thirsty before the examination, you can drink water in your mouth.

2. Fasting can make the gastroscope probe clear in the field of view of the gastric body, more accurately diagnose the disease, and provide a reliable basis for the future diagnosis of the disease. Don't be nervous during the examination, cooperate with the doctor, especially when the gastroscope reaches the throat during the gastroscopy. If you are nervous, you can choose a gastroscopy, so that you can complete the examination in your sleep.

At least 6 hours.

In order to clearly see the mucous membrane of the digestive tract, it is necessary to make the area to be examined clean, i.e., there is no food and no blood clots. If the gastroscopy is done in the morning, no food or drink will be avoided and smoking will be prohibited after 8 p.m. on the day before the examination. Eat foods that are easy to digest with less residue for dinner the day before.

Because even if the patient drinks a small amount of water, the color of the gastric mucosa can change, such as in the natural lesions of significant atrophic gastritis, the gastric mucosa can turn red after drinking water, so that the diagnosis is wrong. If the gastroscopy is done in the afternoon, the patient can drink some sugar water before 8 a.m. on the same day, but cannot eat anything else, and do not eat at noon. In the case of pyloric obstruction.

Gastric lavage must be performed the night before the examination to thoroughly wash the stomach contents until the flushed reflux fluid is clear. Before the tube is withdrawn after gastric lavage, the patient is placed in a supine position with his head down and his feet high to allow the residual fluid in the stomach to be completely discharged. Gastric lavage should not be performed on the same day because it can change the color of the gastric mucosa after gastric lavage.

If a barium swallow has been done, the barium swallow may attach to the gastrointestinal mucosa, especially the ulcer lesions, making the diagnosis of fiber gastroscopy difficult, so the gastroscopy must be done 3 days after the barium swallow examination.

During gastroscopy, you should fast for 8-10 hours, and you can eat a warm liquid or semi-liquid diet after 1 or 2 hours after the examination, and you can resume your normal diet the next day.

Gastroscopy generally requires fasting for more than 6 hours, and the longer the fasting time, the better for gastroscopy, but because of the patient's tolerance, gastroscopy is generally checked in the morning. Fasting and water fasting after 8 p.m. and fasting for a long time can ensure that the stomach is empty and there is no food residue, which is to make it easier to observe. If you do a gastroscopy in the afternoon, not in the morning, you generally fast for at least 6 hours, and you can drink a little light liquid food in the morning, mainly to make the food empty quickly.

Some patients who have undergone esophageal cancer surgery or cardia cancer surgery have a significant delay in gastric emptying, and 6 hours of fasting may not meet the requirements, so they often need to fast for 10 hours or even longer, and sometimes even let the patient eat a liquid diet for 2-3 days, and fasting and water after 7 pm the day before the examination, all of which are for better examination.

That is, if you don't eat a meal, for example, if you want to go for a gastroscopy at noon, you don't have to eat breakfast, if it's in the afternoon, you can have some breakfast and skip lunch.

Hello, glad you asked, your question was.

In general, before gastroscopy.

Ask not to eat as much as possible.

Because gastroscopy is to insert a fiber-optic tube into the stomach.

This allows you to see what's going on in the stomach.

Try to drink as little water as possible, but people should not die of thirst, if you really drink it.

Drink a little.

The most important thing before gastroscopy is to empty the stomach, and it is generally recommended to empty the stomach for more than 4 to 6 hours. In addition, it is necessary to complete the electrocardiogram and hepatitis B 5 tests to observe whether there are any contraindications to gastroscopy. Because gastroscopy is a traumatic test, if no biopsy is taken after gastroscopy, it is recommended to eat a light diet one hour later.

If pathological examination is performed by gastroscopy, it is generally recommended to fast for 2 to 3 hours after gastroscopy, and the diet for the later 2 to 3 days is mainly light and cold liquid food.

First of all, it is recommended that patients should rule out loss of appetite caused by organic diseases, such as inflammation of the gastrointestinal tract, ulcers, or polyps. In such cases, patients can be confirmed by gastroscopy and colonoscopy. Secondly, the color ultrasound or CT of the liver, gallbladder and spleen should be improved to rule out the presence of organs in the cavity of the digestive tract, which causes anorexia symptoms.

If the patient does not find any clear abnormalities in the examination, he can take oral drugs to promote appetite, such as multi-enzyme tablets, yeast tablets, compound digestive enzyme capsules, oral liquid or tablets. If the patient is identified with an organic disease at the time of the examination, the cause should be treated first, and then oral drugs to promote digestion should be given.

It's okay to do it one night in advance, generally don't eat after 8 p.m., and don't eat indigestible food and fruits for dinner.

1. Gastroscopy requires fasting for several hours: generally fasting for 12 hours, that is, fasting and fasting after 20:00 the day before the examination;

2. It takes a few hours for the stomach to empty: In general, for mixed foods, it takes about 4-6 hours for the stomach to completely empty. Liquids take a short time to empty and high-fat solid foods take a long time to empty.

I remember the last time I had a gastroscopy, I just.

In the morning without eating and drinking, this question you should.

It is time to consult a doctor carefully, they will be even more.

Specialized. Stomach problems are difficult to treat, but as long as they are strictly followed.
