The causes of anemia vary, and treatment is determined by the underlying etiology. In iron deficiency anemias, iron supplements are used to support adequate blood production. For anemias related to chronic diseases, the primary treatment approach is the management of the underlying chronic condition. In very severe cases of anemia, hospitalization and blood transfusion may be necessary. This treatment decision is made after a comprehensive evaluation of various factors, including the duration of anemia, the patient's age, and overall health status.
