The degree of anemia can usually be classified as can be classified as mild, moderate, severe and very severe, and the cause of anemia can be classified as iron deficiency anemia, megaloblastic anemia and thalassemia.
If the infant is mildly anemic, the patient’s diet can be adjusted, with appropriate intake of iron-rich foods such as pig’s blood, pig’s liver, etc., and medicines such as ferrous sulfate, ferrous fumarate, or chelated iron should be taken under the guidance of the doctor. In case of severe anemia, blood transfusion should be used according to the doctor’s diagnosis.
