A blood pressure of 120/80 mmHg is normal for pregnant women, but it also depends on the baseline blood pressure of the pregnant woman prior to pregnancy. Generally, if a pregnant woman’s current blood pressure is more than 30/15 mmHg higher than the blood pressure before pregnancy, it may also be a pre-pregnancy hypertension state, and if a pregnant woman’s blood pressure exceeds 140/90 mmHg, it is a pregnancy hypertension. It is important for pregnant women to monitor their blood pressure regularly, to do a glucose tolerance test, and to pay attention to the prevention of hypertension and gestational diabetes during pregnancy. It is very important for pregnant women to monitor their blood pressure. It is recommended to measure blood pressure once a week and pay attention to whether there is foamy urine and other conditions. If a pregnant woman finds foamy urine, it is important to measure blood pressure promptly, which may be caused by high blood pressure in pregnancy, such as elevated urine protein.
