An electronic sigmoid proctoscopy is not particularly painful, there may be some discomfort during the procedure, but it is mostly tolerable. Sigmoidoscopy is an examination of the sigmoid colon and rectum to rule out intestinal diseases. This is a relatively simple test and requires no special preparation before the test, as long as the feces are evacuated and the rectum is empty. Electronic sigmoid proctoscopy can cause discomfort in some people, but the degree of discomfort is not very serious and can be tolerated by most people. However, some people have lesions in the sigmoid colon or rectum, such as inflammation, polyps, tumors, etc., and if the examination causes damage to the lesion area, the pain will be more serious. For people with healthy intestines, the discomfort is reduced accordingly. For people with a low tolerance level, local anesthesia can be administered before the examination to reduce discomfort.
