GDM is characterized by decreased insulin sensitivity, decreased insulin secretion, or a combination of both. Women with GDM are at significant risk for overt T2DM later in life, and postpartum insulin sensitivity and secretion in women with GDM has not been quantified, limiting our ability to optimize screening for overt T2DM. In addition, compliance with currently recommended postpartum T2DM screening by OGTT is poor. Quantification of postpartum insulin sensitivity and secretion in women at high risk for T2DM will inform strategies to improve diagnostic strategies. Continuous glucose monitoring (CGM) is a new technology that may be useful to identify women with persistent hyperglycemia. Understanding maternal glycemia and physiology that drives glycemia in the postpartum period is limited. Completion of this study will define postpartum maternal glycemia, quantify insulin secretion versus insulin sensitivity defects, and demonstrate the feasiblity of using continuous glucose monitoring to identify women most at risk for overt T2DM.
