Internal hemorrhoids are located on the dentate line and are formed by pathological changes in the supporting structures of the anal cushion, the venous plexus and the anastomotic branches of the arteries, resulting in congestion and hypertrophy of the anal cushion and displacement. The main symptoms of internal hemorrhoids are bleeding and prolapse. The bleeding of internal hemorrhoids is mostly painless and intermittent, and the amount of bleeding is usually variable, which can be caused by a variety of reasons, such as stool friction, internal hemorrhoid shedding, local infection, etc. 1. Stool friction: Since stool is dry and hard, it will repeatedly rub internal hemorrhoids during defecation, which leads to bleeding. It is recommended to consume more foods rich in high fiber, such as oats, corn, spinach, etc., and drink enough water to soften the stool and relieve the symptoms of bleeding; 2. Internal hemorrhoid shedding: The bleeding occurs due to increased intra-abdominal pressure caused by coughing, sneezing, straining during defecation, or damage to the trabeculae of internal hemorrhoids caused by weak vein walls, etc. If the bleeding is serious, you can use some hemostatic drugs for treatment under the doctor’s guidance, such as phenolsulfonamide and tranexamic acid, etc.; 3. Local infection: the mucosa of internal hemorrhoids is invaded by pathogens, such as bacteria and viruses, and damage occurs, which may cause internal hemorrhoids to bleed. It can be treated with potassium permanganate solution sitz bath under the guidance of doctor, and also some oral antibiotics, such as metronidazole, cephalosporin, etc. Generally after the above treatment, the bleeding symptoms of internal hemorrhoids can be relieved. If the bleeding symptoms do not ease for a long time, or if jet bleeding occurs, you should immediately go to the hospital for pressure to stop the bleeding or surgical treatment to avoid the occurrence of anemia caused by long-term repeated bleeding or massive bleeding.
