About chronic hypertension

Chronic hypertension is high blood pressure that is present before 20 weeks of pregnancy. Pregnancy does not cause this condition, but a woman's tendency to have high blood pressure may be first discovered during pregnancy.

If you have mild chronic hypertension, without other complications, you and your baby can do as well as those who do not have this condition.

Increased risks

If you have chronic hypertension, you may be at higher risk of the following:

Hypertension and pregnancy

  • If you have hypertension, you may have more frequent ultrasound examinations, blood testing, and tests to monitor the baby's heartbeat. You may need to see your doctor or nurse more frequently.

  • You may need medication to control your blood pressure.

  • Rarely, hospitalization is necessary.

  • Early delivery is sometimes recommended, which might mean that the baby would stay for a time in the Intensive Care Nursery.
