Why does a postpartum baby have anemia?

During the puerperium, infant anemia may arise from multiple factors, both physiological and pathological. Physiological reasons include hemorrhagic anemia, which may be related to frequent sucking on nipples without timely feeding supplementation, or increased blood loss due to the resumption of menstruation during breastfeeding. On the other hand, deficiency anemia due to lack of hematopoietic materials is also a common issue, especially iron deficiency. Since infants rely on external sources for hematopoietic materials, improper dietary supplements or insufficient iron content in breast milk can easily lead to iron-deficiency anemia.
On the pathological level, hereditary anemia is a genetically related disease with varied manifestations, such as hemolytic anemia and hypochromic microcytic anemia, which may require specific medications like hydroxyurea. Thalassemia, also known as hemoglobin synthesis disorder anemia, is another hereditary blood disease affecting hemoglobin synthesis. Mild cases may show no obvious symptoms, while severe cases may present with pallor and hepatosplenomegaly, requiring early diagnosis, appropriate treatment measures, and consideration of blood transfusion therapy when necessary.
Upon detecting signs of anemia in infants, prompt medical attention is necessary for specific diagnosis through blood tests, bone marrow examination, and following medical advice for treatment.
