What are the dangers of anemia to pregnant women?

Anemia is quite harmful to pregnant women, because once a pregnant woman develops anemia, her physical condition will become worse, her plasma protein concentration will decrease, her immune ability will decrease, and the possibility of infection will be greater, and she will also be prone to infection after delivery. Anemia in pregnant women can also reduce the blood's ability to transport oxygen, making the body more susceptible to hypoxia, causing the heart rate to increase, blood flow to speed up, and the heart to be overloaded.

Anemia is a common disease among women and children in my country, among which iron deficiency anemia is the most common. The iron reserves in pregnant women's bodies must not only meet the synthesis of their own hemoglobin, but also meet the needs of fetal development, which makes pregnant women a high-risk group for iron deficiency anemia. And with the increase of gestational age, the incidence of iron deficiency anemia in pregnant women gradually increases. Anemia is not good for pregnant women and fetuses. For pregnant women, the harm is mainly manifested in: First, due to anemia, the plasma protein concentration of pregnant women is low, the antibodies produced are few, the function of macrophages is weakened, which reduces immunity, poor disease resistance, and is prone to infection.

For the fetus, since the fetus is the main receptor tissue for iron, fetal tissue has an advantage in the process of competing for the absorption of maternal serum iron. Iron flows through the placenta in a unidirectional manner and is not transported back from the fetus to the mother. Therefore, the degree of fetal iron deficiency is generally not too serious. However, when the mother is severely iron deficient, low hemoglobin and low oxygen intake can cause chronic hypoxia in the fetus, leading to fetal growth retardation, premature birth, stillbirth, and neonatal anemia. This type of baby has a pale complexion, poor growth and development of all organs throughout the body, lower intelligence than normal babies, and slow reaction.

If anemia in pregnant women is not treated actively, the burden on the heart will increase, which can easily lead to myocardial hypoxia and may also cause ischemic cardiomyopathy. In severe cases, it may cause congestive heart failure. If anemia in pregnant women causes a significant decrease in hemoglobin, it can cause great damage to the myocardium. In addition, pregnant women with anemia are very likely to suffer shock during childbirth.
