If there is severe bleeding from internal hemorrhoids, it is recommended to promptly conduct an anoscopy to determine the exact locations and amount of bleeding. Generally, bleeding from internal hemorrhoids is painless, so it is often underestimated by patients. If the bleeding is heavy or persists for a long time, it is advised that patients undergo surgery as soon as possible to ligate and stop the bleeding, or combine this with oral hemostatic drugs for symptomatic treatment to avoid exacerbation of the bleeding and resulting anemia. Repeated bleeding from internal hemorrhoids can likely lead to varying degrees of anemia. If repeated bleeding occurs, or if the anemia worsens and leads to severe anemia, further treatment with blood transfusions may be necessary to correct the anemia.
