Which condition is a common hypertensive disorder in pregnancy?

Gestational hypertension is indeed a common hypertensive disorder that occurs during pregnancy. It is defined as new-onset high blood pressure that develops after 20 weeks of gestation without the presence of protein in the urine or other signs of preeclampsia. This condition can lead to complications for both the mother and the fetus if not monitored and managed appropriately.

Gestational hypertension is significant because it typically does not predate pregnancy, allowing for differentiation from chronic hypertension. The onset during pregnancy often indicates an association with placental health and maternal well-being, and understanding its management is important in prenatal care. Early detection and monitoring of blood pressure can help prevent progression to more severe conditions, such as preeclampsia, which is associated with more serious maternal and fetal complications.

Other options listed do not classify under hypertensive disorders of pregnancy. For instance, hyperemesis gravidarum is related to severe nausea and vomiting, while gestational diabetes pertains to glucose intolerance during pregnancy. Placental abruption involves the placenta separating from the uterus prematurely, and while it can be associated with hypertensive disorders, it is not categorized directly as one itself. Thus, gestational hypertension stands out as the primary hypertensive disorder typically encountered in pregnancy.
