Women with chronic
high blood pressure require special medical care
before, during, and after their pregnancies.
- Some blood pressure medications are not
recommended for use during pregnancy and breast-feeding. Talk to your health
professional if you take blood pressure medicines and are pregnant or planning
a pregnancy.
- High blood pressure (140/90 mm Hg or higher) during a
pregnancy increases the risks of:
- Preeclampsia. Nearly 1 in 4 pregnant women
with chronic high blood pressure will develop
preeclampsia.1
- Fetal growth problems (intrauterine growth
restriction, or IUGR).
- Placenta
abruptio.
Many women with chronic high blood pressure need little or no
medicine during pregnancy. Blood pressure usually falls during early pregnancy,
so medicine is often not needed unless blood pressure increases to higher
levels. Some women with blood pressure as high as 179/109 may not require
medicine for their high blood pressure during pregnancy.1
Undiagnosed chronic high blood pressure and pregnancy
High blood pressure is a disorder with few or no symptoms. When
planning a pregnancy, see your health professional for a review of pregnancy
risks, such as high blood pressure.
Women with elevated blood pressure during pregnancy receive
frequent blood pressure readings, blood tests, and urine screens for signs of
preeclampsia.
Typically, if a woman's blood pressure remains high for more than
12 weeks after delivery, she is likely to have ongoing (chronic) high blood
pressure.1
