When it comes to colonoscopy, many people are most afraid of drinking laxatives? It is true that drinking laxatives does not feel good. In fact, the doctor is worried that the colonoscopy patients do not drink laxatives well, and they are afraid that everyone will not insist on drinking them, and they will not clean up!

1. Why do you need to “dry” three cups of laxatives before colonoscopy?

Recalling the colonoscopy, many people frowned at the mention of laxatives. Why is it even dry "three cups of laxatives"?

The first cup of laxatives is to be taken the day before the colonoscopy examination. Usually, the patient drinks about 1000 ml of laxatives after eating a small amount of liquid food.

The second and third cups should be taken 4-6 hours before the colonoscopy. The patient should drink 2000 ml within 1 hour. If there is constipation symptoms, it may be necessary to increase the water intake by 500 to 1000 ml.

Drinking so much liquid all at once makes it really uncomfortable to have a full stomach, and this laxative is not water, and it has a taste that makes it difficult to swallow.

The unpleasant laxative is actually polyethylene glycol plus various electrolytes , is basically harmless to the human body , at most it can't be drunk or pulled. A large amount of medicinal liquid enters the intestinal tract and flushes away various things in the intestinal tract. It will not affect the intestinal absorption, nor will it cause the intestinal tract to secrete other substances, and it will not cause electrolyte disturbance.

In colonoscopy, bowel preparation is the key to the success or failure of colonoscopy. Doctors prescribe laxatives, which are used to clear the intestines, clear the stool, and prevent feces and fecal water from remaining in the intestines, which affects the accuracy of colonoscopy and the safety of treatment.

On the one hand, if the bowel is not well prepared and the stool is not cleared, it is possible to not see the condition of the bowel and miss some lesions; on the other hand, even if the colonoscopy is very safe, it cannot Guaranteed 100% will not cause damage to the intestines, in the unfortunate event of perforation, injury, and excessive stool in the intestines will increase the risk of complications.

It can be seen that from the perspective of safety and accuracy before colonoscopy, even if laxatives are difficult to drink, everyone must take them according to the doctor's instructions, according to the time and amount.

Second, in order to clean up and not suffer in vain, do these points before colonoscopy

1. Eat semi-fluid, slag-free and easily digestible food before colonoscopy, do not eat soy sauce, vegetables, and fruits

Vegetables and fruits that are not easy to digest will cause food to remain in the intestinal cavity. Therefore, it is best not to eat such foods 2 days before the colonoscopy. You can eat semi-fluid and easily digestible foods such as porridge and rotten noodles. In addition, colored foods such as soy sauce and red wine will affect the color of the stool, which is not conducive to observing whether the stool is bloody, so it is not suitable for consumption.

2. Big mouth, divided drinking, and walking to enhance the effect

When drinking laxatives, the longer it stays on the tip of the tongue, the more unbearable the taste is, so try to drink as much as you can to ease the pain. Many people can't stand drinking 2L of water at a time, can be arranged to drink it within 2 hours, and drink 250ml every 15 minutes or so . After drinking water, you can walk back and forth to help flush the bowel and achieve better preparation.

Generally, after taking laxatives, diarrhea will occur about half an hour, usually 7-10 times, until no solid fecal residue can be seen , which means that the bowel preparation is qualified.

3. Although colonoscopy is uncomfortable, once it is done, it can guarantee safety for 5 to 10 years

The doctor suggested : If you are over 45 years old and have not had a colonoscopy, you must have a colonoscopy before the end of the year. A colonoscopy can take care of you for 5 to 10 years without any problems, and you will not get colon cancer. .

Why is colonoscopy so important?

According to clinical statistics, 80%-95% of colon cancers develop from polyps, and it generally takes 5 to 10 years to develop from polyps to colon cancer. Excision, the pathological findings are benign, only need to be reviewed every year, no recurrence for 2-3 years in a row, basically 5-10 years can be reviewed.

However, if no colonoscopy is performed, there will be no other abnormalities in the human body. The polyps will slowly develop into adenomas, and further develop into severe dysplasia, which may eventually develop into cancer.

As far as current medical technology is concerned, no other examination can well replace colonoscopy, which is still the "gold standard" for colorectal cancer screening.
