A study led by the Medical University of Vienna found that continuous glucose monitoring (CGM) in women with gestational diabetes reduces the risk of having a baby with excessive birth weight. The study of 375 women showed that CGM led to a lower rate of large-for-gestational-age babies (4% vs 10%) compared to traditional finger-prick testing. CGM allows women to track their blood sugar levels in real-time, enabling them to make adjustments to their lifestyle or insulin therapy. However, the study also found that strict sugar management may influence the risk of insufficient fetal growth, requiring further investigation.
