The serious consequences of hemorrhoids are caused by the symptoms of hemorrhoids, the two most important symptoms of hemorrhoids are blood in the stool and prolapsed hemorrhoids. First, when hemorrhoids bleed badly in the stool there will be dripping or shooting blood during or after the stool, and blood in the stool is very frequent, leading to severe anemia in patients when their own hematopoietic function cannot compensate for blood loss from hemorrhoids. If the active bleeding cannot be stopped, it can even lead to acute hemorrhagic shock, endangering the patient’s life. Secondly, prolapsed hemorrhoids, severe hemorrhoids when the hemorrhoid nucleus is prolapsed can not be retracted, it will lead to local impaction, ischemia and necrosis of the hemorrhoid nucleus. If the patient has a history of diabetes and low immunity, it can cause serious infection and even life-threatening necrotizing fasciitis.
