A Canadian postpartum follow-up study of different gestational glucose tolerance groups, based on the antenatal glucose challenge test (GCT) and 100 g oral glucose tolerance test (OGTT) using the National Diabetes Data Group criteria, showed that each degree of gestational glucose intolerance predicts distinct trajectories of β-cell function, insulin sensitivity and glycemia in the first three years postpartum which drive the differential risk of future T2D [4]. Here, INS is linked to Glucose intolerance.
