When will fetal malformation occur after pregnancy? What should you pay attention to during pregnancy to prevent fetal malformation?

Pregnancy is a happy event for a family, and it is also a very important time for expectant mothers, especially during the early stages of pregnancy when the fetus is still unstable and needs to take in various nutrients. Many mothers worry about whether the baby will be born with deformities, so it is necessary to understand the time period that is most likely to cause fetal deformities, and do a good job of prevention and daily care.

When will fetal malformations occur after pregnancy?

The most common period for fetal malformation is the last three months of pregnancy, that is, before the 12th week of pregnancy, which is what we usually call the "early pregnancy". Because many important organs of the baby will differentiate and develop during this period, such as the heart, nerves, bones, genitals and mouth. Therefore, the last three months of pregnancy is a critical period for preventing fetal malformation.

3-8 weeks of pregnancy: The fetus's organs begin to differentiate. If disturbed by external factors, abnormal organ development may occur.

After 9 weeks of pregnancy: The fetus's brain, teeth, upper jaw and external genitalia have not yet been fully differentiated. External interference will mainly affect the fetus's intelligence, organ and tissue dysfunction, or external genitalia malformations.

What to pay attention to during pregnancy to prevent fetal malformations

1. Have a physical examination before pregnancy, and deal with and correct any problems you find in a timely manner. This will make preparing for pregnancy safer and more scientific.

2. Eat a balanced and comprehensive diet during pregnancy, do not be partial or picky about food, and do not eat junk food.

3. Stay away from ionizing radiation. Although small doses of ionizing radiation may not necessarily cause death, safety comes first.

4. Quit smoking and drinking before pregnancy to provide high-quality eggs and sperm.

5. Try not to get infected or have a fever, and do not use medications indiscriminately. Use medications under the guidance of a professional doctor.

6. If you have an infection before pregnancy, you should actively seek treatment.

7. Regularly supplement iron and folic acid to reduce fetal anemia and malformations.

8. During pregnancy, you should have regular physical examinations and necessary auxiliary examinations, such as ultrasound, chromosome examination, etc.

Causes of fetal malformations during pregnancy

1. Drug factors. Many drugs, including Chinese patent medicines, have the risk of causing fetal malformations.

2. The radioactive factor is of course ionizing radiation. Radiation may be present in places where babies are taken for X-rays and where trains and airplanes undergo safety inspections.

3. Biological infection factors, early intrauterine viral infection, bacterial infection, cytomegalovirus infection, and toxoplasmosis infection may all lead to fetal malformations.

4. Severe lack or excess of certain important nutrients and trace elements, such as severe iron deficiency and folic acid deficiency.
