How painful is the enteroscope that everyone is afraid of? Does everyone feel unbearable pain during the examination?

Patients will not feel severe pain during colonoscopy, because colonoscopy is a mild pain examination, and ordinary examination will not cause too serious intestinal damage. Colonoscopy is a non-invasive examination method, so patients generally do not have to worry too much before colonoscopy, and there will be no severe pain during colonoscopy.

First of all, let's talk about a digression. Let's go to the hospital to see if the gastroenterologist or the doctor in the gastroenterology department has suggested that you have a colonoscopy, instead of saying that my stomach is complaining and I want to have a colonoscopy.

ok, let's talk about colonoscopy: colonoscopy usually lasts about 3-6 minutes. At present, most of them are painless colonoscopy, which means that some intravenous anesthetics will be used to make you sleepy. During the examination, the doctor used a colonoscope with a diameter of about 2.5 cm, with a camera at the front end and an optical fiber in the middle to transmit the image of the colorectal region to check whether there was any abnormality. The colonoscope is inserted into the rectum and then into the other end of the large intestine. The lens can bend and move in the colon along the bend of the colon. At the same time, air will enter your colon, which will expand the colon, facilitate the movement of the mirror and make the vision clear. Generally, I don't feel too much during the operation. After the examination is completed, the colonoscopy is slowly withdrawn. During colonoscopy, if a doctor sees something that may be abnormal, he may take out a small amount of tissue for biopsy and identify these abnormal things as benign or malignant lesions. In many cases, colonoscopy can make an accurate diagnosis. And some benign polyps can be removed under the microscope.

Precautions and preparations for colonoscopy: First, inform the doctor about these conditions: whether you are pregnant, previous lung condition and heart condition. Are you allergic to drugs? If you have diabetes or take drugs that may affect blood coagulation, you may need to adjust these drugs before colonoscopy.

3. Check the diet of the day before. Usually you can't eat solid food the day before. Including liquid diet may be limited to clear liquids-boiled water, tea and juice. There is no milk or cream, broth and carbonated drinks (of course, there are differences in different places. In principle, the cleaner, the clearer the test results). Avoid confusion between drinking red liquid and bleeding. You may not be able to eat or drink anything after the morning before the exam.

take laxatives. According to the types of laxatives, laxatives can be taken the day before colonoscopy, or the night before surgery and the morning before surgery. In some cases, if defecation is not ideal after taking laxatives, additional enema may be needed.
