Abstract:

Anemia is the most common complication during pregnancy, and iron deficiency is the most common cause of anemia during pregnancy. In order to conceive and adapt to the growth of the fetus during pregnancy, women have experienced significant anatomical and physiological changes, which begin to affect every organ system of the body in the early pregnancy. The increase of blood volume of follow-up pregnant women exceeded the increase of blood components, and the demand for iron for fetal growth and development increased sharply. When the iron storage or intake in the body could not meet the needs of the mother, it would lead to relative or absolute iron deficiency, leading to iron deficiency anemia. Anemia during pregnancy increases the risk of puerperal infection, placental abruption, maternal death, hypertensive disease during pregnancy, cesarean section, postpartum hemorrhage, fetal growth restriction and premature delivery, and is related to the cognition, autism and mental disorders of the offspring. This article will discuss the related causes of iron deficiency, anemia during pregnancy, the recommendations of iron agents and the hazards of iron overload.
