What maternal condition is characterized by high blood pressure after 20 weeks of gestation without other signs of preeclampsia?

Gestational hypertension is defined as the development of high blood pressure that arises after the 20th week of pregnancy, without the presence of significant proteinuria or other signs associated with preeclampsia. This condition can occur in previously healthy women and typically resolves after delivery.

Gestational hypertension is distinct because it lacks the severe complications that preeclampsia presents—namely, organ dysfunction and other severe warning signs. Monitoring is essential, as some cases may progress to preeclampsia. By definition, gestational hypertension is also different from chronic hypertension, which refers to high blood pressure that predates pregnancy or occurs before the 20-week mark. Eclampsia, on the other hand, involves seizures in a woman with preeclampsia, making it far more severe than gestational hypertension.

Understanding gestational hypertension is crucial for monitoring maternal and fetal health and implementing appropriate interventions.
