The most important symptom of hemorrhoids is blood in the stool and prolapse. Repeated bleeding during stool can cause the body to lose a large amount of iron and cause iron deficiency anemia. This is because under normal circumstances the absorption and excretion of iron is kept in balance and the loss of iron is very small, normal adult men lose no more than 2 mg of iron per day, while patients with blood in the stool lose more than 3-4 mg of iron if the daily blood loss exceeds 6 to 8 ml. The normal human male contains a total of 50 mg of iron per kilogram of body weight, and the female is about 35 mg per kilogram of body weight, if long-term blood in the stool, losing a lot of iron, so that the total amount of iron in the body is lower than normal, can cause iron deficiency anemia. If you find that you have hemorrhoids, you need to treat them even to avoid complicating the treatment afterwards. Iron deficiency anemia can occur with blood loss from hemorrhoids, and in severe cases, there can be weakness, rapid heartbeat, and pallor. Patients in the early stages do not have too obvious conditions. All of these symptoms can be relieved and disappeared by treating hemorrhoids. Patients also need to drink plenty of water to keep their bodies hydrated when hemorrhoids are found. Another major symptom of hemorrhoids is the prolapse of internal hemorrhoids. The internal hemorrhoids that are prolapsed outside the anus are held by the sphincter muscle and the venous return is blocked, while the arterial blood is still being input to increase the size of the hemorrhoid nucleus until the arterial blood vessels are pressed shut and a thrombus forms, resulting in a hard, painful hemorrhoid nucleus that is difficult to send back into the anus. The traditional view is called “strangulated internal hemorrhoids”. However, in the case of external hemorrhoids, the formation of thrombus is more common and is therefore associated with pain, and when the nucleus of the hemorrhoid is prolapsed and cannot be returned, it is also called “embedded hemorrhoid”. The danger of hemorrhoids is actually not small, and some people may think that hemorrhoids are no big deal. The actual fact is that you can find a number of different types of hemorrhoids that can be found in the marketplace. Therefore, if the internal hemorrhoid is embedded for a long time, necrosis is bound to occur. The necrosis is often confined to the mucous membrane part of the hemorrhoid nucleus, but there are also cases where it invades other parts of the body. There are reports from abroad that the thrombus in the hemorrhoid nucleus spreads upward and the necrotic area extends to the rectal wall, resulting in severe sepsis in the pelvis. This is rare, but must be taken seriously by clinicians. (2) Infection After the nucleus is embedded, there are different degrees of infection, and the patient has symptoms such as shortness of breath, anal swelling, etc. At this time, the infection is mostly confined to the anal area, and if it is strongly reset, it is easy for the infection to spread and cause abscesses in the submucosa, perianal or sciatic rectal fossa. Even sepsis and liver abscess can be formed. Fatal portal vein sepsis associated with embedded hemorrhoids has been reported abroad. All in all, hemorrhoids are harmful to the human body in many ways and can become more troublesome if left untreated. It should be taken seriously by your doctor and each patient should be treated carefully and seriously. Patients with hemorrhoids do not have to be too nervous, as the above serious complications can be completely eliminated from occurring with proper handling and early treatment. The incidence of hemorrhoids is high, and the likelihood of recurrence is still relatively high for hemorrhoid patients after surgical treatment or other therapies. The reason for this is that, in addition to incomplete treatment, inattention to hemorrhoid prevention is also an important factor.
