Reframing gestational diabetes mellitus through two new paradigms: Early detection and lifelong intergenerational...

Gestational diabetes mellitus (GDM) has traditionally been regarded as a transient metabolic disorder limited to pregnancy, with management directed primarily towards reducing obstetric and perinatal complications. Yet a growing body of evidence over the past two decades compels a fundamental redefinition. Two emerging paradigms expand the physiological and clinical understanding of GDM. The first recognizes early-onset GDM (e-GDM), diagnosed in the first trimester, as a severe metabolic phenotype reflecting pre-existing dysfunction. The second reinterprets GDM as a lifelong, intergenerational condition, a sentinel event marking heightened risk for chronic cardiometabolic disease in both mother and offspring. Together, these frameworks demand a transition from short-term obstetric management to long-term preventive physiology, integrating early diagnosis, mechanistic understanding, and intergenerational care.
