From the beginning of confirming pregnancy, it is necessary to go to the hospital for various examinations, and only through these examinations can we understand the development of the fetus. If fetal developmental abnormalities are detected, timely treatment can be taken. When is fetal malformation formed after pregnancy, which is the biggest concern for the fetus?
Exposure to harmful substances or the use of certain medications within 12 weeks of pregnancy can easily lead to fetal malformations. Especially during the period of 6-12 weeks of pregnancy, which is the stage of cell differentiation and the initial formation of fetal organs, deformities are most likely to occur.
As the gestational age increases, cell differentiation is completed after 12 weeks of pregnancy, and this stage enters the stage of tissue and organ development, which reduces the risk of fetal malformation. However, this does not mean that the fetus has no possibility of malformation at this stage. Fetal malformation is a gradual process of growth and development, so it is necessary to go to the hospital for detailed examination every gestational week. Once abnormalities in fetal development are found, they should be dealt with in a timely manner.
From the perspective of eugenics and child rearing, it is recommended to undergo an ultrasound examination to detect abnormalities between 22-24 weeks of pregnancy, and a follow-up examination at 26 weeks of pregnancy. Through ultrasound, various organs can be seen, which is also the most direct way to check for fetal abnormalities. In short, in order to avoid fetal malformations, radiation and harmful substances should be avoided before and during pregnancy, and medication should not be taken indiscriminately during pregnancy.
