Complications of Gestational hypertension

About complications: Complications of Gestational hypertension are secondary conditions, symptoms, or other disorders that are caused by Gestational hypertension. In many cases the distinction between symptoms of Gestational hypertension and complications of Gestational hypertension is unclear or arbitrary.

Complications of Gestational hypertension: The effects of high blood pressure during pregnancy vary depending on the disorder and other factors. According to the National High Blood Pressure Education Program (NHBPEP), preeclampsia does not in general increase a woman's risk for developing chronic hypertension or other heart-related problems. The NHBPEP also reports that in women with normal blood pressure who develop preeclampsia after the 20th week of their first pregnancy, short-term complications--including increased blood pressure--usually go away within about 6 weeks after delivery.1

Maternal complications acutely can include pulmonary edema, thrombotic complications, renal failure, and death. Preeclampsia can evolve into eclampsia, leading to maternal seizures. One specific subset of signs and symptoms known as the HELLP Syndrome (Hemolysis, Elevated Liver Enzymes, and Low Platelets) is a cause of extensive morbidity. In the United States, hypertensive disorders of pregnancy account for nearly 15 percent of maternal mortality; throughout the world these conditions are responsible for more than a third of maternal deaths. The vast majority of these deaths and most infant deaths are due to preeclampsia and eclampsia, arising either de novo or superimposed on chronic hypertension. Long-term sequelae may also result. Women with chronic hypertension have an obvious long-term risk from the persistent hypertension. However, women with preeclampsia, despite the resolution of the disorder postpartum, are also at increased risk of cardiovascular disease in later life compared to women with pregnancies without preeclampsia. 2

Fetal complications of hypertensive disorders of pregnancy include growth restriction, prematurity, and stillbirth. In addition, there is evidence that the intrauterine milieu in a hypertensive pregnancy may, by mechanisms related to the failure of the fetus to exercise full growth potential, confer increased risk of cardiovascular events in adult life. 2
