High blood pressure, also called hypertension, is very common. In the United States, high blood pressure happens in 1 in every 12 to 17 pregnancies among women ages 20 to 44.3
High blood pressure in pregnancy has become more common. However, with good blood pressure control, you and your baby are more likely to stay healthy.
The most important thing to do is talk with your health care team about any blood pressure problems so you can get the right treatment and control your blood pressure before you get pregnant.
Getting treatment for high blood pressure is important before, during, and after pregnancy.
Complications from high blood pressure for the mother and infant can include the following:
- For the mother: preeclampsiaexternal icon, eclampsiaexternal icon, stroke, the need for labor induction (giving medicine to start labor to give birth), and placental abruption (the placenta separating from the wall of the uterus).1,4,5
- For the baby: preterm delivery (birth that happens before 37 weeks of pregnancy) and low birth weight (when a baby is born weighing less than 5 pounds, 8 ounces).1,6 The mother’s high blood pressure makes it more difficult for the baby to get enough oxygen and nutrients to grow, so the mother may have to deliver the baby early.
