Pregestational diabetes (type I or II): Diabetes mellitus diagnosis predates pregnancy
Gestational diabetes mellitus (GDM): Any degree of glucose intolerance initially diagnosed during pregnancy
Diagnosis by oral glucose tolerance test from 24- to 28-weeks gestation
GDM, by definition, resolves following pregnancy, although recurrence in subsequent pregnancies is common
Increased risk of developing type II diabetes (40-50% within 10 years)
Controversy exists regarding risk of anomalies in GDM
Anomalies in GDM may reflect undiagnosed type II diabetes
