It is possible to check for hemorrhoids by having a colonoscopy. A colonoscope is a long, thin, and bendable medical instrument that is about 1 cm wide. During the examination, the patient’s anus is inserted into the anal canal, and the patient’s rectum and anus can be visually observed for any abnormal reactions. It is possible to observe whether there are masses, inflammatory lesions, nodules, intestinal diseases, etc. If you see a mass in the location of the anal opening, it is possible that you have hemorrhoids, because hemorrhoids are mainly manifested by swollen fleshy bulb-like objects that also appear to prolapse outside the anus, etc. It is also not excluded that they are anal polyps, anal papillomas, etc. The actual fact is that you will be able to see the hemorrhoids by going to the hospital for anoscopy, and you need to deal with the treatment in time to avoid more serious situations after the diagnosis.
