Necessity of taking folic acid tablets for pregnant women

Folic acid tablets are especially important for pregnant women. Lack of folic acid in the first three months of pregnancy can cause neural tube defects in the fetus, thereby increasing the incidence of split-brain and anencephaly. Secondly, pregnant women should take folic acid tablets regularly to prevent congenital malformations such as low birth weight, premature birth and cleft palate (cleft lip). Women of appropriate age should take 0.4 mg of folic acid tablets every day starting from 3 months before pregnancy and continue throughout the pregnancy.

1. Prevent anemia in pregnant women. The body of pregnant women needs folic acid to produce normal blood cells. According to a survey report, the anemia incidence rate among women of childbearing age in my country is 20.6%. Insufficient intake of folic acid tablets may also cause anemia in pregnant women.

2. Reduce the risk of birth defects. After 13 years of research on the "China-US Cooperation on the Prevention of Neural Tube Defects Project", 250,000 medical inquiries have confirmed that women of childbearing age who take 0.4 mg of folic acid tablets every day from the beginning of pregnancy preparation can reduce the incidence of neural tube defects in the fetus by 85%, reduce the incidence of cleft lip and palate in the fetus by 50%, reduce the occurrence of congenital heart disease by 35%, reduce the incidence of major epidermal malformations in newborns by 15% and reduce the neonatal mortality rate by 20%.

3. In the second and third trimesters of pregnancy, in addition to the growth of the fetus, the mother's blood flow, breasts, and embryonic growth cause the need for folic acid tablets to increase dramatically. If folic acid tablets are insufficient, pregnant women are prone to placental abruption, pregnancy-induced hypertension, and megaloblastic anemia; the fetus is prone to intrauterine language development retardation, premature birth, and low birth weight, and the development and brain growth of the fetus after birth will be affected.
