When does blood pressure decrease during pregnancy?

Women who are normotensive entering pregnancy typically experience a decrease in blood pressure toward the end of the first trimester. This decrease is thought to be secondary to the marked vasodilation that occurs despite the increase in plasma volume that comes with pregnancy.

What happens to blood pressure during pregnancy?

Women who are normotensive entering pregnancy typically experience a decrease in blood pressure toward the end of the first trimester. This decrease is thought to be secondary to the marked vasodilation that occurs despite the increase in plasma volume that comes with pregnancy. Blood pressure usually falls by 5 to 10 mm Hg and remains at this lower level throughout pregnancy until the third trimester, when it rises to return to prepregnancy values. For the majority of women with chronic hypertension, blood pressure changes also follow this same pattern. As a result, some hypertensive women become normotensive during pregnancy, and others who remain hypertensive can have their antihypertensive medications tapered. These physiological changes may confuse the diagnosis of chronic hypertension when a woman presents for prenatal care for the first time in the second trimester once the physiological decrease has occurred and is now normotensive. In such cases, the increase to prepregnancy values in the third trimester may suggest gestational hypertension. It may not be until elevated blood pressures persist beyond 12 weeks postpartum that, in retrospect, the correct diagnosis of chronic hypertension is recognized.

Can hypertension cause blood pressure to change during pregnancy?

As a result, some hypertensive women become normotensive during pregnancy, and others who remain hypertensive can have their antihypertensive medications tapered.
