Question: How are hypertensive disorders in pregnancy classified?

Answer:

In 2000, the National High Blood Pressure Education Program Working Group revised the classification system for this set of conditions. Four categories are now recognized for hypertension in pregnancy: chronic hypertension, gestational hypertension, preeclampsia, and chronic hypertension with superimposed preeclampsia. The American College of Obstetricians and Gynecologists has adopted the Working Group’s system.
