New Gestational Diabetes Guidelines

The new Australian guidelines for the management of Gestational Diabetes have recently been released.  The guidelines for diagnosis are now more clear and the recommended daily blood glucose levels have been lowered.  This is to enhance the health outcomes for both baby and mother but many are questioning the strict new protocols.  Particularly those Mum's who had Gestational diabetes in a previous pregnancy which used less stringent blood glucose levels.


It continues to be a routine policy for pregnant women to be tested for Gestational Diabetes at 24-28 weeks gestation and some may be tested earlier if symptoms are present or the patient has a prior history.  It is no longer required to consume a high carbohydrate diet for a few days before the test, however it is recommended you eat normally leading up to the test.  A diagnosis of Gestational Diabetes will be made if your:

Fasting glucose is over 5.1 mmol/L

1 hour glucose is over 10.0 mmol/L

2 hour glucose is over 8.5 mmol/L


For those who are diagnosed with Gestational Diabetes, the new recommended blood sugar levels are:

BSL <5.0 mmol/L before breakfast

BSL <7.4 mmol/L 1 hour after a meal or snack

BSL <6.7 mmol/L 2 hours after a meal or snack


These changes have been made to aim for the best outcomes for women and their babies.  While some may see them as strict, the level of evidence does show achieving these guidelines is best for Mum's and their babies.  Blood sugar levels are affected by many things, but primarily they are related to the amount of carbohydrate you eat, the type of carbohydrate you eat and how much exercise you do.

It is recommended that those diagnosed with Gestational Diabetes consult with a Dietitian to determine the most appropriate nutrition plan for you and your baby.  Eat Smart Nutrition Consultants can assist you in managing your Gestational Diabetes, improving the health of Mum and Baby and lowering your risk of diabetes following the birth.  Check out our website for more details on where to find us and when.
