Causes, Treatment and Prevention of Preeclampsia

Martin L Gimovsky

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the liver and kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in women whose blood pressure had been normal. Left untreated, preeclampsia can lead to serious even fatal complications for both you and your baby. If you have preeclampsia, the most effective treatment is delivery of your baby. Even after delivering the baby, it can still take a while for you to get better. The exact cause of preeclampsia involves several factors. Experts believe it begins in the placenta the organ that nourishes the fetus throughout pregnancy. Early in pregnancy, new blood vessels develop and evolve to efficiently send blood to the placenta. In women with preeclampsia, these blood vessels don't seem to develop or function properly. They're narrower than normal blood vessels and react differently to hormonal signaling, which limits the amount of blood that can flow through them.
