Early Gestational Diabetes Mellitus: Screening and Management

With increasing maternal age and obesity rates in reproductive-aged women, gestational diabetes has increased in prevalence. This has generated interest in broadening screening for glycemic dysfunction in pregnancy, to detect both previously undiagnosed diabetes as well as early gestational diabetes. Clinical guidance is limited, however, due to the shortage of high-quality evidence and the lack of uniform diagnostic criteria. This review will provide a summary of the screening and diagnosis of GDM before 20 weeks of gestation.
