A hemoglobin of 80g/L is relatively severe and falls within the range of moderate anemia. Anemia is a condition in which the volume of red blood cells in the body’s peripheral blood is reduced below the lower limit of the normal range and is unable to transport enough oxygen to the tissues, resulting in tissue hypoxia. Based on hemoglobin concentration, anemia is divided into mild, moderate, severe, and very severe anemia, in the order of >90g/L, 60~89g/L, 30~59g/L, and <30g/L. Therefore, 80g/L is moderate anemia. Different causes of anemia have different treatment principles. Treatment for the cause of anemia and eradication of the cause is the key to the treatment of anemia. For example, patients with aplastic anemia need to be given cyclosporine orally, and patients with acute leukemia need to be given cytarabine, erythromycin, and other drugs for chemotherapy. In daily life, if symptoms of anemia appear, you should consult a doctor in time to clarify the diagnosis of anemia, find the cause of anemia, and actively treat it. At the same time, certain anemia can be avoided through effective self-management, causative prevention, dietary prevention, and lifestyle prevention. Specific treatment should be carried out under the guidance of physicians.
