Abstract
Sixty years after the landmark publication by O'Sullivan and Mahan, the current paper seeks to review and place into context the importance of gestational diabetes (GDM) both as a marker of increased risk of adverse maternal and fetal pregnancy outcomes and as an indicator of future maternal and infant health risks. We review the evolution of GDM as a diagnosis, the ongoing debate regarding diagnostic approaches, the underlying pathophysiology, and the epidemiology and the importance of GDM in the context of the global epidemics of diabetes and obesity. Focusing on clinical management, we review lifestyle-based therapy and pharmacotherapy for GDM, consider obstetric management, and outline the short-term and lifelong health risks posed by a GDM diagnosis.
