What is the procedure for colonoscopy?

Keep a happy mood during the examination and avoid stress factors. You will take laxatives the day before the examination to clean the intestines, otherwise the examination results will be affected. Lie on your left side with your knees slightly bent. A colonoscope is inserted into the rectum through the anus and into the large intestine, and a fiber hose with a light source and a miniature electronic camera at the end is used to examine intestinal lesions. The examination situation will be directly observed by the doctor on a computer monitor nearby. If necessary, a colonoscope will be used to sample the intestine for further biopsy. The entire examination process will take 20 to 30 minutes.
