The Australasian Diabetes in Pregnancy Society (ADIPS) has been revising its consensus guidelines for the testing and diagnosis of gestational diabetes but these have not yet been translated into a unified approach to the condition in Australia. Controversy over the diagnosis of gestational diabetes persists internationally. Key practice points for general practitioners arising from the revised guidelines are reviewed.
- The Australasian Diabetes in Pregnancy Society has been revising its guidelines for the testing and diagnosis of gestational diabetes. Ongoing controversy over diagnostic criteria is delaying a unified approach to the condition within Australia.
- Gestational diabetes is associated with adverse maternal and neonatal outcomes at even lower blood glucose levels than previously recognised.
- Universal testing with a one-step 75 g two-hour oral glucose tolerance test at 24 to 28 weeks of gestation is recommended.
- Treatment ideally involves a multidisciplinary approach focusing on patient education, dietary modification and lifestyle intervention. Medication should be initiated when treatment targets are not achieved by diet alone.
- General practitioners play a crucial role in detecting undiagnosed pre-existing diabetes in high-risk women before or in early pregnancy, and ensuring timely postpartum follow up and risk factor modification to reduce the risk of future diabetes.
