Patient's question:
When applying for the maternity certificate, the doctor said that folic acid should be supplemented in the three months before pregnancy and the first three months of pregnancy. If you take Fergason brand prenatal nutrition soft capsules continuously during pregnancy to supplement folic acid (recommended by the doctor during the lecture), will it be harmful to the fetus? In the end, the doctor also recommended getting the rubella vaccine. I heard that you cannot get pregnant within three months. I want to ask how long the effectiveness of a single dose of the rubella vaccine lasts?Doctor's answer:
Hello: As long as you are injected, you will not get sick again! However, folic acid must be actively supplemented. Women should take 0.4 milligrams of folic acid supplements daily from one month before pregnancy to three months after pregnancy to prevent most neural tube defects in the fetus. It is worth mentioning that women taking folic acid should do so under the guidance of a doctor. Additionally, the following points should be noted:1. It is essential to start taking folic acid one month before pregnancy. The purpose of emphasizing the need to start before pregnancy is to maintain a certain level of folic acid in women's bodies to ensure early embryonic development has adequate folic acid nutrition. According to research, it takes four weeks for women to correct their folic acid deficiency after taking folic acid. Only in this way can sufficient folic acid meet the needs of nervous system development during the sensitive period of early fetal neural tube formation, and it must be taken consistently in the first three months of pregnancy to achieve the best preventive effect.
2. Women in low-prevalence areas for neural tube defects should also supplement folic acid. The incidence of neural tube defects in China is higher in northern regions than in southern regions and higher in rural areas than in urban areas. Therefore, some people believe that women in low-prevalence areas can skip folic acid supplementation during pregnancy. However, this misconception may become a hidden risk for the birth of children with neural tube defects. According to surveys, a significant portion of women of childbearing age in low-prevalence areas still lack folic acid. Therefore, women in low-prevalence areas must not be complacent before pregnancy.
3. Can taking folic acid supplements guarantee that you won't have a child with neural tube defects? Taking folic acid supplements is to prevent folic acid deficiency in pregnant women'
