Information for Patients


High Blood Pressure in Pregnancy

If you are pregnant, high blood pressure can cause problems for you and your unborn baby. You may have had high blood pressure before you got pregnant. Or you may get it once you are pregnant - a condition called gestational hypertension. Either one can cause low birth weight or premature delivery of the baby.

Controlling your blood pressure during pregnancy and getting regular prenatal care are important for the health of you and your baby. Treatments for high blood pressure in pregnancy may include close monitoring of the baby, lifestyle changes, and certain medicines.

Some pregnant women with high blood pressure develop preeclampsia. It's a sudden increase in blood pressure after the 20th week of pregnancy. It can be life-threatening for both you and the unborn baby. There is no proven way to prevent it. Most women who have signs of preeclampsia are closely monitored to lessen or avoid complications. The only way to "cure" preeclampsia is to deliver the baby.

Postpartum Care

Also called: Post-pregnancy health

Taking home a new baby is one of the happiest times in a woman's life. But it also presents both physical and emotional challenges.

  • Get as much rest as possible. You may find that all you can do is eat, sleep, and care for your baby. And that is perfectly okay. You will have spotting or bleeding, like a menstrual period, off and on for up to six weeks.
  • You might also have swelling in your legs and feet, feel constipated, have menstrual-like cramping. Even if you are not breastfeeding, you can have milk leaking from your nipples, and your breasts might feel full, tender, or uncomfortable.
  • Follow your doctor's instructions on how much activity, like climbing stairs or walking, you can do for the next few weeks.
  • Doctors usually recommend that you abstain from sexual intercourse for four to six weeks after birth.

In addition to physical changes, you may feel sad or have the "baby blues." If you are extremely sad or are unable to care for yourself or your baby, you might have a serious condition called postpartum depression.
