The spectrum of the disease ranges from mildly elevated blood pressures with minimal clinical significance to severe hypertension and multiorgan dysfunction. Understanding the disease process and its impact on pregnancy is of utmost importance, as hypertensive disorders remain a major cause of maternal and perinatal morbidity and mortality worldwide (Table 5-1).
