Summary

Overdiagnosis is a growing problem in healthcare for patients and the system at large. This review explores the potential for overdiagnosis in gestational diabetes mellitus (GDM) screening for healthy pregnancies. The analysis shows that intensified GDM screening increases incidence without clear benefits, suggesting universal screening could be a contributor to unnecessary diagnoses. The review also identifies the lack of an established mechanism to define or measure overdiagnosis in GDM screening.
