When referring to hypertensive disorders, what is the "20 weeks" criterion?

The "20 weeks" criterion is significant as it helps to differentiate between gestational hypertension and chronic hypertension in pregnant individuals. Specifically, this criterion establishes that if a woman develops high blood pressure after the completion of 20 weeks of gestation, it is characterized as gestational hypertension. In contrast, if high blood pressure was present before this gestational age, it is classified as chronic hypertension. This distinction is crucial for appropriate management and monitoring throughout the pregnancy, as it influences treatment decisions and the potential risks to both the mother and the fetus. Understanding this timeframe aids healthcare providers in delivering tailored care for those experiencing hypertensive disorders during pregnancy.
