Usually the normal value of blood pressure during pregnancy is 140/90 mmHg, and clinicians prefer to keep the blood pressure of pregnant women at 130/80 mmHg to allow for a certain buffer space. Patients should receive more attention if they have the following high-risk backgrounds: 1, new mothers, pregnant women who are too young or older than 35 years old; 2, patients with excessive mental stress or central nervous system dysfunction; 3, during cold seasons or excessive temperature changes, pregnant women with gestational hypertensive disease or family history, as well as the presence of chronic hypertension, nephritis, and history of diabetes mellitus, should also receive attention; 4, for obese, especially short and fat people, malnourished people, as well as high uterine tension, such as excessive amniotic fluid, twin births, diabetes, or huge babies, or even gravidity, should also be noticed. Poor socioeconomic status will also be included in the scope of key concerns, so it is more desirable to keep the blood pressure of pregnant women at 130/80 mmHg, to give them room for blood pressure to rise, and also have the opportunity to actively detect and treat to avoid adverse consequences.
