The main method of injection treatment for hemorrhoids is for internal hemorrhoids, which involves injecting a sclerosing agent into the nucleus of the internal hemorrhoids, and the main medication applied nowadays is the elimination of hemorrhoids, also known as elimination of hemorrhoids injection. By injecting a sclerosing agent into the internal hemorrhoids, the proteins of the nucleus of the internal hemorrhoids are denatured, causing the nucleus to harden and shrink and adhere to the intestinal wall. For early internal hemorrhoids there is still some effect, but the long term effect is not as good as surgical treatment of hemorrhoids, because it does not eliminate the root of the removal of the internal hemorrhoid nucleus. There is still a certain risk of recurrence if you have bad habits, such as a spicy, stimulating diet, dry stools, and long bathroom breaks. Many patients may relapse after a year and still need surgical treatment, but the recent results are still better. The advantage is that there is no pain, no special rest is needed, and it can be a good treatment for internal hemorrhoids that have relatively mild symptoms.
