Did you know that up to 10-15% of pregnancies are affected by hypertension? About 5% of those cases are in women previously known to have hypertension (termed ‘chronic hypertension’), prior to pregnancy. Another 5-8%, develop hypertension within the pregnancy (termed ‘gestational hypertension’ or ‘pregnancy-induced hypertension’.)
Hypertensive disorders are characterized by blood pressures consistently ranging 140/90 or greater. Women with chronic hypertension (existing before pregnancy, or diagnosed before 20 weeks of gestation) may require blood pressure medications to control their blood pressure, even throughout the pregnancy. Those medications should be reviewed with your healthcare provider, to assess their safety in pregnancy, even before conception.
