Anemia is a common disease among women and children in China, with iron deficiency anemia being the most common. Pregnant women's body iron reserves not only to meet their own hemoglobin synthesis, but also to meet the needs of fetal development, which makes pregnant women become a high incidence of iron deficiency anemia. The incidence of iron deficiency anemia in pregnant women gradually increases with the growth of gestational weeks. Anemia is not good for both pregnant women and fetuses, and for pregnant women, the harm is mainly manifested in the following: First, due to anemia, the plasma protein concentration of pregnant women is low, the antibodies produced are few, and the role of macrophages is weakened, which leads to a decline in immunity, poor resistance to disease, and susceptibility to infection. The lower the hemoglobin content of the mother, the greater the possibility of postpartum infection. Secondly, when a pregnant woman is anemic, her blood's ability to carry oxygen is low, and she will not have any uncomfortable symptoms when she is chronically mildly anemic, but when she is severely anemic or acutely loses too much blood, her heart will beat faster, her output will increase, and her blood flow will speed up, which will aggravate her heart's burden. If it continues to develop, myocardial hypoxia can occur, leading to anemic heart disease or even congestive heart failure. When hemoglobin <50g/L, pregnant women will experience myocardial damage. Third, the tolerance to blood loss decreases. During delivery, anemic pregnant women may suffer shock and death due to decreased tolerance of bleeding even if it is in the normal range.

For the fetus, because the fetus is the main receptor tissue for iron, in the process of competing for the uptake of maternal serum iron, fetal tissues dominate, and iron through the placenta is a one-way operation, will not be reversed from the fetus to the mother's reverse transport, so the general degree of iron deficiency in the fetus will not be too serious. However, when the mother is seriously deficient in iron, due to low hemoglobin and low oxygen uptake, it can cause chronic fetal hypoxia, resulting in fetal growth retardation, preterm delivery, stillbirth, and can cause neonatal anemia. This kind of baby is pale, the growth and development of all organs of the body are poor, the intelligence is also poorer than normal babies, and the reaction is slow.

Anemia of pregnancy, one is to prevent, before pregnancy that is, should be actively treated for hemorrhagic diseases, such as excessive menstruation, hookworm, etc., in order to increase iron reserves. Strengthen the family planning, avoid having too many children. Pay attention to nutrition during pregnancy, eat more iron-rich foods, such as liver, eggs, lean meat, cabbage, etc., daily intake of iron about 21 to 28mg before. Iron supplements should be given from the 4th month of pregnancy, 0.3g of ferrous sulfate daily, and it is best to supplement vitamin C at the same time, which is conducive to the absorption of iron. Secondly, we should give active treatment to pregnant women suffering from anemia, according to the severity of anemia, give different doses, on the hemoglobin value & lt; 60g / L, close to the expected date of delivery or short-term need for cesarean section of pregnant women, can be given to transfusion to correct anemia.
