Continuous Glucose Monitoring for Women With Gestational Diabetes

At diagnosis of GDM, women will receive education on the management of GDM with lifestyle and need to monitor glucose with SMBG. Within one week of GDM diagnosis, all participants will be asked to use a blinded CGM (Freestyle Libre Pro IQ,) during a run-phase. Women randomized to the control arm, will be asked to intermittently wear a blinded CGM sensor (Freestyle Libre Pro IQ) during 14 days at least two time points in pregnancy (at 31.0-33.6 weeks and between 36.0-38.6 weeks). For women diagnosed with early GDM (\<20 weeks), blinded CGM will be needed 3 times in pregnancy with a first time at 20.0-23.9 weeks. Women randomized to the intervention arm will be recommended tu use the rt-CGM (Freestyle Libre 3) till the delivery. In line with normal routine, a 75g OGTT will be performed between 6-24 weeks postpartum to screen for glucose intolerance. Participants will be asked to also wear a blinded CGM (Freestyle Libre Pro IQ) at this last study visit.
