The expectant mother\’s physical examination should be carried out at least three months before pregnancy. Experts say prenatal testing may reveal fetal malformations or congenital dysplasia before it is too late. If you can get checked during the pregnancy preparation stage and explain your medical history and some factors that may affect the baby\’s normal development to the doctor, it will be very beneficial to give birth to a healthy baby.
The first prenatal check-up is usually within three months of pregnancy and requires a detailed examination of all parts of the pregnant woman\’s body. At this time, some complications of the fetus can be discovered, such as abnormal heart development, abnormal thyroid development, etc., so that solutions can be taken as early as possible.
In the second stage of pregnancy, that is, from 12 weeks to 17 weeks of pregnancy, you generally need to check once a month, and from 26 weeks to 40 weeks, you need to check every two weeks. Depending on the specific situation, some examination items may be added, such as screening for Down syndrome, neural tube defects, etc. at 15-20 weeks.
Experts point out that screening for Down syndrome in pregnant women under 35 years old can exclude high-risk pregnant women, while high-risk groups (including pregnant women over 35 years old) must undergo amniocentesis for further diagnosis.
B-ultrasound and color Doppler ultrasound are the most commonly used methods for prenatal examination. Some expectant mothers think that color Doppler ultrasound can see more clearly than B-ultrasound, but this is not accurate. Color Doppler ultrasound simply increases blood flow and vascular conditions and is suitable for the diagnosis of vascular diseases. Usually used between 22 and 24 weeks. The development of fetal internal organs and other organs can be seen through B-ultrasound. In comparison, B-ultrasound is also more economical than color Doppler ultrasound.
Experts remind pregnant women with the following conditions to do prenatal check-ups:
diabetics;
Those who work in a long-term strong magnetic field or are exposed to chemicals for a long time;
Those who have taken antiviral drugs during early pregnancy
Marriage between close relatives greatly increases the incidence of genetic diseases. Common diseases include congenital deafness and muteness;
Pregnant women themselves have bad habits, such as smoking.
