How should anemia be treated?

The treatment of anemia should be formulated according to its cause and severity, and can mainly be divided into the following points: 1. **Drug therapy**: Depending on the type of anemia. For example, iron supplements (such as ferrous sulfate tablets, iron dextran granules, ferrous gluconate syrup, etc.) can be used for iron deficiency anemia; vitamin B12 and folic acid supplementation can be used for megaloblastic anemia. 2. **Blood transfusion therapy**: Blood transfusion is recommended for chronic anemia patients with hemoglobin levels below 60g/L or patients with acute blood loss exceeding 30% of total blood volume. 3. **Surgical treatment**: For severe anemia unresponsive to drug or blood transfusion therapy, such as aplastic anemia, allogeneic hematopoietic stem cell transplantation may be considered. 4. **General supportive care**: Emphasis should be placed on rest, dietary adjustment, and ensuring adequate intake of nutrients such as iron and vitamin B12.
