(1) A physical examination should be performed before conception. This is a checkup for both husband and wife. Especially for women who are preparing to get pregnant, in addition to the routine examination of heart, liver and kidney, the examination of reproductive system should be focused. If you are suffering from sexually transmitted diseases, you should wait for the treatment to be cured before you can get pregnant. (2) Take oral folic acid 3 months before pregnancy. Taking folic acid can avoid neurological developmental diseases. If you do not take folic acid in time before pregnancy, you should continue to take supplementation after pregnancy until 12 weeks of pregnancy. (3), Extra attention should be paid to health care during pregnancy, and regular prenatal checkups should be ensured. (4), Down’s syndrome screening is performed at 16 to 20 weeks of pregnancy. This test is performed by extracting the blood of the pregnant mother and testing the amount and concentration of various substances contained in the blood to determine some possible fetal disorders. (5) Amniocentesis is done after 20 weeks of pregnancy. This test is not required for normal young pregnant mothers. Studies have shown that the older the mother is, the higher the incidence of congenital dysmorphism and malformations. It is important to note that this test has a 0.5% chance of causing a miscarriage as a result. (6) Pay more attention to indicators such as blood sugar and blood pressure. Advanced maternal age is prone to combined heart disease of pregnancy, gestational hypertension syndrome and gestational diabetes. As the blood volume in the pregnant mother’s body increases significantly compared to the non-pregnant period, the burden on the heart increases. It is likely that pregnant mothers who already have heart disease will have to terminate their pregnancy early because they cannot tolerate it. (7) It is more difficult to have a natural delivery at an advanced age, so you need to prepare in advance. The pelvis of senior pregnant mothers is harder, the ligaments and soft birth canal tissues are less elastic, the uterine contraction force is correspondingly weakened, which may easily lead to prolonged labor, even obstructed labor, fetal birth injury and asphyxia, the indications for cesarean section are higher, usually 90% of senior mothers choose cesarean section.
