Another major symptom of hemorrhoids is internal hemorrhoids prolapse. The internal hemorrhoids protruding outside the anus are clamped by the sphincter, venous return is blocked, and the arterial blood is still infused, which increases the volume of the hemorrhoids, until the arterial blood vessels are compressed, thrombosis, the hemorrhoids become hard and painful, and it is difficult to return to the anus Inside.
The symptoms are blood in the stool and prolapse. Repeated bleeding during stool can cause a large amount of iron to be lost in the body and cause iron deficiency anemia. This is because under normal circumstances the absorption and excretion of iron are in a balanced state, and the amount of iron loss is very small. The daily iron loss of normal adult men does not exceed 2 mg, and the patient with blood in the stool, if the daily blood loss exceeds 6～ 8 ml will lose more than 3 to 4 mg of iron. The total iron content of normal human male is 50 mg/kg body weight, and the female is about 35 mg/kg body weight. If long-term blood in the stool will lose a large amount of iron, the total iron content in the body will be lower than normal, which can cause iron deficiency anemia .
Iron-deficiency anemia caused by blood loss from hemorrhoids generally develops slowly, and may have no symptoms or mild symptoms in the early stage. When the anemia is severe or progresses quickly, it will appear pale, fatigue, loss of appetite, palpitations, increased heart rate and physical strength After the activity, shortness of breath, edema, etc., some patients may have neurological symptoms such as irritability, excitement, irritability, etc. Some people think that it is caused by the lack of iron enzymes in the cells. These symptoms can all disappear after correcting anemia and treating hemorrhoids. Therefore, if hemorrhoids are found, they should be treated as soon as possible to avoid the above symptoms and complicate the treatment.
Another major symptom of hemorrhoids is internal hemorrhoids prolapse. The internal hemorrhoids protruding outside the anus are clamped by the sphincter, venous return is blocked, and the arterial blood is still infused to increase the volume of the hemorrhoids, until the arterial blood vessels are compressed, thrombosis, the hemorrhoids become hard and painful and difficult to return to the anus Inside. The traditional view is called "strangulated internal hemorrhoids." However, the external hemorrhoids seen in the clinic are more common with thrombus formation, so they are often accompanied by pain. When the hemorrhoids prolapse and cannot be returned, it is also called "incarcerated hemorrhoids".
