Blood pressure is the force of blood pushing against the walls of blood vessels called arteries. The arteries bring blood from the heart to your lungs, where it picks up oxygen and then moves to your organs and tissues. The organs and tissues use the oxygen to power their activities. Blood vessels called veins return the blood to the heart.
High blood pressure, also called hypertension, is very common. In the United States, high blood pressure happens in one in every 12 to 17 pregnancies among women ages 20 to 44.3.
What do the blood pressure numbers mean?

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 five pounds, eight ounces). The mother’s high blood pressure makes it more difficult for the baby to get enough oxygen and nutrients to grow, so the mother
