Application of CGM in GDM During and After Pregnancy

Ling-Jun LiSingapore Speaker Is Continuous Glucose Monitoring Ready for Screening and Monitoring of Gestational Diabetes in Asian Populations?Gestational diabetes mellitus (GDM) is highly prevalent across Asia, where genetic susceptibility, rapid urbanization, and uneven access to antenatal care contribute to rising maternal and neonatal complications. Current screening and monitoring rely on oral glucose tolerance testing (OGTT) and self-monitored blood glucose (SMBG), but both have limitations, including sparse capture of glycaemic variability, patient burden, and missed postprandial excursions. Continuous glucose monitoring (CGM) provides near real-time glucose profiles that can support more responsive management, and emerging studies suggest that early-pregnancy CGM metrics may help predict GDM diagnosed later in pregnancy. However, the evidence remains heterogeneous, with variation in diagnostic criteria, population characteristics, device type, adherence, and background care pathways. Given Asia’s high and growing GDM burden, region-specific evidence is needed to inform guideline and policy development. This talk will synthesize findings from Asian studies, with a particular focus on work from Singapore, and discuss what is required for CGM to move from promising tool to routine practice in GDM screening and management in Asian populations.
