Anemia is not always caused by a deficiency in elements.

In cases of iron deficiency anemia, it is due to a lack of iron. Megaloblastic anemia occurs because of a deficiency in folate or vitamin B12. However, clinically, there are many other types of anemia, such as aplastic anemia, hemolytic anemia, myelodysplastic syndromes, leukemia, etc. The anemia caused by these diseases is not due to a deficiency in elements, but is due to the diseases themselves affecting bone marrow hematopoiesis, leading to anemia. Therefore, it is necessary to clearly diagnose the cause of anemia in order to treat it effectively.

What indicators are used to diagnose anemia?

To determine if someone is anemic, we should look at the red blood cell count and hemoglobin level in a complete blood count. Currently, hemoglobin level is the commonly used indicator clinically. Normal hemoglobin levels are 110~150g/L for women and 120~160g/L for men. Anemia is diagnosed when the hemoglobin level falls below the normal range. Based on the amount of hemoglobin, anemia can be classified into very severe, severe, moderate, or mild. Hemoglobin levels above 90g/L indicate mild anemia, levels between 60~90g/L indicate moderate anemia, levels between 30~60g/L indicate severe anemia, and levels below 30g/L indicate very severe anemia.

Which department should I go to for anemia?

Anemia is classified as a hematological disease and requires further diagnosis and treatment in the department of hematology. In severe cases of anemia, the body can be in a state of ischemia and hypoxia, which can induce the occurrence of acute cardiovascular and cerebrovascular diseases, such as acute angina and cerebral thrombosis. Therefore, patients with acute anemia need to have red blood cell transfusions to support treatment and correct the anemia. If the anemia is not severe, red blood cell transfusion is not necessary, but it is important to complete tests like anemia indicators, bone marrow aspiration, and bone marrow biopsy to further clarify the cause of the anemia and treat it accordingly.

How should pregnant women supplement for anemia?

Under normal circumstances, if anemia symptoms are confirmed after pregnancy, further examination is still necessary for active symptomatic treatment. Normally, the specific cause of the anemia can be identified, whether it is due to iron deficiency, folate deficiency, or B12 deficiency. According to the specific cause of anemia, oral medication can be administered for symptomatic treatment, which can effectively alleviate the symptoms. After taking oral medication, it is also necessary to regularly check the rise in hemoglobin levels to properly manage the condition.

Can anemic people donate blood?

Patients with anemia cannot donate blood. After donating blood, due to the reduction of blood volume, it may worsen anemia and cause symptoms such as dizziness, excessive sweating, nausea, vomiting, and other manifestations of low blood pressure. In severe cases, it can even induce acute cardiovascular and cerebrovascular accidents, so patients with anemia cannot donate blood. Clinically, the requirements for blood donors include not being anemic, weighing more than 45 kilograms, and being free of infectious diseases.
