A pregnant woman’s systolic blood pressure is 113 mmhg and diastolic blood pressure is 70 mmhg, and this blood pressure value belongs to the normal range. The normal range of blood pressure for pregnant women is 90~139 mmhg systolic and 60~89 mmhg diastolic. As long as the blood pressure is in the above range, it is completely normal; systolic and/or diastolic blood pressure higher or lower than the above standard is called high blood pressure and low blood pressure, respectively. Blood pressure is not constant during pregnancy and may fluctuate. Early and mid-pregnancy blood pressure is low, systolic blood pressure generally does not change significantly, diastolic blood pressure due to peripheral vasodilatation, blood dilution and placenta formation of arterial and venous short circuit can be mildly lowered, blood pressure can be mildly increased after the 24th to 26th week of pregnancy, but generally does not exceed the normal value. Pregnant women with blood pressure of 113/70 mmHg do not need special treatment and observation is sufficient. However, the blood pressure during pregnancy should be detected dynamically, and if it is found to decrease or increase, the doctor should be consulted, and if it is serious, reasonable intervention should be made according to the individual’s situation.
