Hypertension is a common medical disorder that affects 10% of all pregnancies and covers a spectrum of conditions namely gestational hypertension, preeclampsia, eclampsia, chronic hypertension and preeclampsia superimposed on chronic hypertension. Hypertension is defined as a diastolic blood pressure of at least 90 mm Hg or a systolic BP of at least 140 mm Hg. Severe hypertension is defined as systolic blood pressure of >160 or diastolic blood pressure >110 mm Hg. The only definitive therapy for gestational hypertension/preeclampsia is delivery. In case of preterm pregnancies, the main objective of expectant management is to improve neonatal outcome if the risks for the mother and child remain acceptable. All women with overt hypertension 140/90 should be hospitalized for assessment of severity of disease. Expectant management includes restricted physical activity, maternal and fetal surveillance, steroids to hasten lung maturity and antihypertensives to protect the mother from the effects of severe hypertension. ACOG recommends antihypertensives when diastolic blood pressure is 105–110 mm Hg or higher. Vaginal delivery is the preferred route of delivery with careful monitoring for early detection of fetal heart rate abnormalities. Eclampsia is defined as the development of convulsions and/or unexplained coma during pregnancy or postpartum in patients with signs and symptoms of preeclampsia. Management includes magnesium sulfate treatment to prevent recurrent seizures, stabilization of maternal condition, control of BP and induction of labor. Chronic hypertension complicates 5% of pregnancies and is characterized by a history of high blood pressure before pregnancy, elevation of blood pressure during first 20 weeks of pregnancy or high blood pressure that lasts longer than 12 weeks after delivery.
