Understanding Preeclampsia and Eclampsia -- Prevention

How Can I Prevent Preeclampsia and Eclampsia?

Preeclampsia is a potentially dangerous condition in which a pregnant woman develops high blood pressure -- or her hypertension worsens -- threatening the health of her unborn child and herself. Preeclampsia, which may develop into eclampsia, may interfere with the placenta's ability to deliver oxygen and nutrition to the fetus. Your baby may be born weighing less than normal, may have other health problems, and may need to be delivered early.

Because no one knows what causes preeclampsia, it is very difficult to know how to prevent it. However, aspirin has been shown to have a protective effect in women with risk factors for preeclampsia. If you have significant risk factors and a history of preeclampsia, your health care provider may recommend that you take a low dose of aspirin daily.
