Hemorrhoids are divided into internal and external hemorrhoids. Bleeding from hemorrhoids generally belongs to internal hemorrhoids or develops into mixed hemorrhoids. Therefore, hemorrhoidal bleeding is due to internal hemorrhoids or mixed hemorrhoids. Hemorrhoids are classified into four degrees: First-degree hemorrhoids do not prolapse. Second-degree hemorrhoids prolapse during defecation when abdominal pressure increases but can retract spontaneously afterward. Third-degree hemorrhoids involve prolapse of the hemorrhoidal tissue that requires manual replacement. Fourth-degree hemorrhoids are incarcerated and cannot be retracted. The treatment of hemorrhoidal bleeding depends on the amount and nature of the bleeding. If it is a small amount of bleeding, conservative treatment is generally sufficient, and the bleeding symptoms will disappear. If the bleeding is significant and persistent, failure to promptly address and surgically treat it may lead to chronic anemia and iron deficiency anemia.
