Patients who have internal hemorrhoids can have a colonoscopy, and the process of doing so will not lead to the aggravation of internal hemorrhoids. The colonoscopy is what we usually call an electronic colonoscope, which is able to enter through the anus and examine directly to the ileocecal region, and can examine the entire large intestine, i.e., the colon in physiological anatomy, and advance observation to see if there are any lesions on the intestinal wall, and if there are diseases such as inflammation, polyps and tumor growth in the intestine. The colonoscopy has a camera, so you can visually see the lesions on the intestinal wall, and this examination is more instructive. In addition, internal hemorrhoids do not affect the colonoscopy, and the colonoscopy will not lead to the aggravation of internal hemorrhoids, which do not affect the entry of the colonoscope through the anus because the nucleus is softer.
