Hypertensive disorders of pregnancy are a serious threat to the health of the mother and child. Normally, the blood pressure after pregnancy does not change with the growth of the gestational weeks, but remains the same as in the absence of pregnancy. Therefore, hypertensive disorders of pregnancy are diagnosed if the blood pressure rises above 140/90 mmHg after pregnancy, especially after 20 weeks of gestation, and if proteinuria or swelling may occur. However, if the blood pressure does not reach the diagnostic criteria, i.e., when 140/90 mmHg, but is 30/15 mmHg higher than the pre-pregnancy basal blood pressure, it should also be taken seriously. For people at risk, they should be encouraged to exercise appropriately, rest reasonably, take calcium supplements, and not strictly limit salt intake. The latest study shows that obese people will strictly limit the intake of fatty categories. Hypertensive disorders during pregnancy are more serious complications of pregnancy. If left unattended and untreated, it is likely that cerebrovascular accidents, placental abruption, eclampsia convulsions and other conditions that seriously endanger the life of mother and child will occur. Therefore, it is important to diagnose and treat hypertension in a timely manner if it occurs.
