what could cause early delivery pregnancy
However, some women develop high blood pressure while they are pregnant (often called gestational hypertension). The effects of high blood pressure range from mild to severe. High blood pressure can harm the mother's kidneys and other organs, and it can cause low birth weight and early delivery. In the most serious cases, the mother develops preeclampsia-or toxemia of pregnancy--which can threaten the lives of both the mother and the fetus.
