When does gestational hypertension typically onset during pregnancy?

Gestational hypertension is specifically characterized by high blood pressure that develops after the 20th week of gestation. This timing is crucial because it differentiates gestational hypertension from chronic hypertension, which may be present before pregnancy or diagnosed prior to the 20-week mark. Identifying the correct timeframe helps healthcare providers monitor pregnant individuals effectively and manage any associated risks for both the mother and the fetus. Conditions that arise before 20 weeks are typically related to pre-existing factors rather than gestational issues. Therefore, the onset of gestational hypertension aligns with the physiological changes that occur later in pregnancy, making the identification of this timing essential for proper diagnosis and intervention.
