Preeclampsia

Preeclampsia is high blood pressure and excess protein in the urine after 20 weeks of pregnancy in a woman who previously had normal blood pressure.Preeclampsia develops only during pregnancy. Risk factors include: history of preeclampsia, first pregnancy, new paternity, age, obesity, multiple pregnancy, prolonged interval between pregnancies, diabetes and gestational diabetes, history of certain conditions, having other health conditions, vitamin D insufficiency,  and high levels of certain proteins. Left untreated, preeclampsia can lead to fatal complications for mother and child. The only cure is delivery of the baby.No one knows  how to prevent preeclampsia. A number of studies have looked into whether taking extra calcium, vitamins, or a low dose of aspirin can help.when preeclampsia is severe, it can affect many organs. Preeclampsia causes the blood vessels to constrict, resulting in high blood pressure and a reduced blood flow that can affect organs in your body, such as your liver, kidneys, and brain.When less blood flows to your uterus, it can mean problems for your baby, such as poor growth, too little amniotic fluid, and placental abruption. In addition, your the baby may suffer the effects of prematurity if you need to deliver early to protect your health. People should make commericials or doctors should make sure to tell their patients so more parents can become aware of this issue.
