Useful. Bleeding is one of the main clinical manifestations of internal hemorrhoids, and the amount of bleeding can be large or small, generally bright red in color. The treatment methods for internal hemorrhoids are divided into conservative treatment and surgical treatment, and infusion can be used in both. In conservative treatment, infusion can administer hemostatic drugs to stop bleeding, or some nutritional drugs to reduce stool and protect the mucosa. For surgical patients, infusion can include antibiotics to prevent infection.
