Q: What is the harm of hemorrhoids?
1. The main symptoms of hemorrhoids are "hemorrhoids" and "hemorrhoids prolapsed". Repeated bleeding during bowel movements can cause a large amount of iron to be lost in the body and cause iron deficiency anemia. Iron is an indispensable and important element in red blood cells. Under normal circumstances, the absorption and excretion of iron are balanced, and the loss of iron is very small. If you have blood in the stool for a long time and lose a lot of iron, making the total iron content in your body lower than normal, it will cause iron deficiency anemia.
2. Another major symptom of hemorrhoids is prolapse of hemorrhoids, causing pain and affecting walking. As the anal cushion is loose, broken, and sagging, the hemorrhoids will eventually prolapse. The hemorrhoids protruding outside the anus are further clamped by the sphincter, causing the venous return to be blocked, and the continuous infusion of arterial blood makes the hemorrhoids larger and larger; until finally the arteries are compressed, thrombosis, and the hemorrhoids become hard and painful , It is difficult to return to the anus, at this time it is called "incarcerated hemorrhoids". If a hemorrhoid is incarcerated for a long time, the following complications may occur.
(1) Necrosis: Hemorrhoids are incarcerated outside the anus. Due to ischemia and venous reflux, a series of pathological changes are caused, local metabolites accumulate, and necrosis will eventually appear. At the beginning, the necrosis is only limited to the mucosal part of the hemorrhoids. If it is not treated in time, the necrosis will extend to the deep part, which may eventually lead to serious infection.
(2) Infection: After hemorrhoids are incarcerated, they often have different degrees of infection. The patient may have symptoms such as tenesmus and anal swelling. At the beginning, the infection is mostly localized in the anus. If repositioned barely, the infection may spread and cause mucosa Lower or deeper infections, or even perianal or sciatic rectal fossa abscess; if the shed bacterial embolus runs along the vein, plus the improper use of antibiotics or no antibacterial drugs, it may form portal bacteremia or even sepsis. Liver abscess can also form. There have been reports of fatal portal sepsis caused by hemorrhoid incarceration abroad.
