Comparing Continuous and Capillary Glucose Monitoring in Pregnant Women with Gestational Diabetes and Previous Gastric Bypass Surgery

What this Trial Is About

Researchers are investigating gestational diabetes in women who have previously undergone gastric bypass surgery. The study aims to understand how continuous glucose monitoring affects treatment and pregnancy outcomes compared to regular capillary glucose measurements during the last trimester. This research focuses on glucose variability and its impact on pregnancy complications such as large for gestational age infants and small for gestational age infants, which are concerns in this group. Participants will be randomly assigned to one of two groups one using continuous glucose monitoring with the FreeStyle Libre 3 device and associated apps, and the other receiving standard care with 7-point capillary glucose measurements. Both groups will receive standard medical care, including visits to a specialized maternity care unit and weekly follow-ups with a diabetologist. Continuous glucose monitoring allows for detailed tracking of glucose fluctuations, including time in target range and episodes of high or low glucose. Throughout the study, participants will have regular glucose assessments from gestational weeks 28 to 42, with monitoring of pharmacological treatments and pregnancy outcomes such as birthweight and week of delivery. The main outcome is adverse pregnancy events measured up to five days postpartum. This study also evaluates how glucose measurements relate to treatment approaches and pregnancy health in women with gestational diabetes after gastric bypass surgery.
