High Fasting Plasma Glucose during Early Pregnancy: A Review about Early Gestational Diabetes Mellitus

Figure 2

Does eGDM mean preexisting prediabetes? The hypothesis is when hyperglycemia has been present (but unknown) before pregnancy, then fasting plasma glucose (FPG) is already increased during early pregnancy while insulin resistance increases after 24 weeks of gestation (WG). Accordingly, oral glucose tolerance will reveal dysglycemia in early postpartum. 1h-PG and 2h-PG: plasma glucose 1 and 2 hours after 75 g oral glucose tolerance test; FPG: fasting plasma glucose; WG: weeks of gestation.
