How much should pregnant women's normal blood pressure be?

The normal blood pressure of pregnant women is the same as that of ordinary adults. The high pressure is between 90-140 mm Hg, and the low pressure is between 60-90 mm Hg. If the blood pressure is found to exceed the normal range during the prenatal examination, it is necessary to be alert to the cause of pregnancy hypertension. If it is not corrected in time, it is easy to cause abortion.
