So, why is there a fetal malformation during pregnancy? Is it caused by insufficient folic acid supplement or something?
Fetal malformation during pregnancy is caused by many factors. Although folic acid deficiency may also lead to fetal malformation, this probability is not great because folic acid exists in our diet. However, folic acid is a B-group water-soluble vitamin, which can't be stored in the body. During pregnancy, the metabolism is accelerated, and folic acid is excreted with the body's metabolism.
Therefore, in order to avoid folic acid deficiency in pregnant mothers, extra folic acid is needed during pregnancy, and 400 micrograms of folic acid is needed every day. If folic acid is insufficient, it will easily affect the development of fetal central nervous system and increase the risk of fetal spine.
The main causes of fetal abnormalities are as follows:
1. Fetal malformation caused by drugs
Pregnant mothers take drugs during pregnancy, which can enter the fetus through the placenta, causing chromosome aberration, gene mutation and cell division interference.
Drug use should be stopped in the first trimester 1- 12 weeks; Use drugs carefully in the second and third trimester of pregnancy, especially some antibiotics and hormones, and strictly follow the doctor's advice to prevent harm to the fetus.
2. Fetal malformation caused by radiation
Radiation can kill cells in the human body. Pregnant mothers must avoid contact with radioactive elements for diagnosis and treatment during pregnancy, and do not use X-rays for abdominal examination in the first trimester.
3. Fetal malformation caused by infection
When pregnant women suffer from rubella, measles, influenza and other viral infectious diseases, pathogens such as bacteria and viruses will invade the placenta, which will easily cause fetal malformation.
4. Malformation caused by chromosome abnormality
When parents have some kind of deformity or defect, the probability of children's deformity is relatively high, that is, genetic problems. When the fetus has chromosomal abnormalities, there will be congenital stupidity, hydrocephalus, big head and small head.
5. Fetal malformation caused by other factors
Alcohol, tobacco, waste water, waste gas, pesticide residue, noise, malnutrition, etc. May cause fetal malformation. Pregnant mothers should try to avoid contact with these substances during pregnancy and have a balanced diet to provide a healthy and safe growth environment for the fetus.
How to prevent fetal malformation?
1. Pre-pregnancy examination
With the popularization of the concept of prenatal and postnatal care, many couples, especially those with physical or genetic diseases, will have prenatal and postnatal care tests before planning pregnancy, so they must consult a doctor and have a detailed examination before pregnancy.
Take folic acid
Folic acid is a kind of vitamin, which plays an important role in the division, growth and nucleic acid synthesis of red blood cells and is an essential substance for human body. Scientific research shows that folic acid can reduce the probability of fetal neural tube malformation, spontaneous abortion and pregnancy reaction, and is taken in the first three months of pregnancy and the third month after pregnancy.
Stop drinking
With the change of working environment, women are more and more fulfilling their self-worth, and social intercourse at work is essential, so drinking has become a very common thing. However, if you continue to drink alcohol during pregnancy, alcohol will not only affect the intelligence of the fetus, but also lead to fetal malformation. In recent years, more and more fetuses are affected by embryonic alcohol syndrome, so pregnant mothers should avoid drinking alcohol.
4. Quit smoking:
Ditto, because of work pressure, if pregnant mothers continue to smoke, it will also cause fetal malformation. Studies have shown that if women who smoke for a long time quit smoking in time at the beginning of pregnancy, the baby's birth weight will be reduced by 20%, the probability of birth defects will be reduced by 5%, and the premature delivery rate will be reduced by 8%.
At the same time, pregnant mothers should also avoid inhaling second-hand smoke, otherwise the smoky air contains a lot of toxins, which will reduce the oxygen intake of the fetus and easily lead to intrauterine hypoxia.
Healthy diet
The nutrition of fetus comes from mother, so the nutrition of mother is very important to the health of fetus. During pregnancy, pregnant mothers should eat more whole grains, beans and protein foods, and also eat more fish rich in DHA, which is good for fetal brain development.
6. Avoid air pollution
Avoid contact with environments containing a lot of chemicals during pregnancy, such as supermarket vegetable areas; Avoid room decoration during pregnancy, such as painting and adding new furniture; If you work on the production line, pregnant mothers should also pay attention to noise and dust.
relieve stress
When women are emotional or under excessive work pressure, they may lead to premature delivery and miscarriage, and the probability of fetal malformation will increase in the state of long-term emotional fluctuation. Therefore, after pregnancy, you should learn to adjust your emotions. If conditions permit, you can relax yourself through exercise and entertainment.
8. Use drugs with caution
Early pregnancy is an important stage of embryo differentiation. If the pregnant mother is exposed to drugs that affect the fetus at this time, the embryo differentiation will be abnormal, leading to fetal malformation. Therefore, drugs should be used with caution throughout pregnancy, and doctors must be consulted.
9. Physical examination on time
Be sure to have a prenatal examination on time during pregnancy. Only in this way can we find and solve all kinds of problems in fetal development in time and reduce the probability of accidents between mother and fetus.
10. End consanguineous marriage
Inbreeding is closely related to genetic diseases and fetal malformations, and the probability of their offspring suffering from genetic diseases and fetal malformations is much higher than that of non-inbreeding people. A large number of facts show that the fertility rate of men and women married by close relatives is relatively low, but the mortality rate of offspring is high, and congenital malformation and hereditary diseases will occur.
Relevant statistical data show that the probability of a cousin getting married with Wilson's disease is 1/64, while the prevalence rate of this disease is only one in four million in the offspring of a normal couple, and the probability of the offspring suffering from congenital idiocy is 150 times that of a non-relative.
Summary:
Every couple wants to be a good student, so we should seriously grasp the above principles, not only know how to be a good student, but also practice it, not just talk but not practice. Only in this way, the future baby will be smart and lovely, and the physique will be outstanding.
