Gestational diabetes (sometimes referred to as GDM) is diagnosed when higher than normal blood glucose levels first appear during pregnancy. From 3 to 8% of pregnant women will develop gestational diabetes around the 24th to 28th week of pregnancy, however, some may be earlier.
While maternal blood glucose levels usually return to normal after the birth of the baby, there is a known increased risk for type 2 diabetes in the mother in the future. Your child may also be at risk of developing type 2 diabetes later in life.
You are at risk of developing gestational diabetes if you:
- Are over 30 years of age
Have a family history of type 2 diabetes
- Are overweight
- Are from an indigenous Australian or Torres strait islander background
- Are from a Vietnamese, Chinese, middle eastern, Polynesian or Melanesian background
- Have had gestational diabetes during previous pregnancies.
