Diabetes is a chronic condition marked by high levels of sugar (glucose) in the blood, caused by the body being unable to produce insulin (a hormone made by the pancreas to control blood glucose levels) or to use insulin effectively, or both. All people with type 1 diabetes, and a proportion of people with other forms of diabetes (such as type 2 diabetes), will require insulin replacement therapy to manage their condition. The Incidence of insulin-treated diabetes in Australia web report presents the latest available data on new cases of type 1 diabetes and insulin-treated type 2 diabetes in Australia from the 2017 National (insulin-treated) Diabetes Register (NDR).

New cases of insulin-treated diabetes in 2017 

According to the NDR, in 2017 there were 29,797 people who began using insulin to treat their diabetes:

  • 2,742 (9%) people were diagnosed with and began using insulin to treat type 1 diabetes
  • 17,358 (58%) people began using insulin to treat type 2 diabetes
  • 9,053 (30%) women began using insulin to treat gestational diabetes
  • 517 (2%) people began using insulin to treat other forms of diabetes.

Note: proportions were calculated excluding those for whom diabetes was unknown (127 cases or 0.4% of total insulin-treated diabetes). Due to rounding, percentages do not sum to 100.
