For every person diagnosed with diabetes, another goes undiagnosed.
Pre-diabetes occurs when your blood glucose level is higher than normal but not high enough to be diagnosed as diabetes – it is the result of your body’s insulin not working effectively. The majority of people diagnosed with pre-diabetes can manage their condition and reduce their risk of developing type 2 diabetes by leading a healthy lifestyle.
The condition is also known as Impaired Glucose Tolerance, Impaired Fasting Glucose or insulin resistance.
Am I at risk of pre-diabetes?
- Do you have high blood pressure?
- Are you overweight?
- Does someone in your family have type 2 diabetes?

If you answered yes to one or more of the following then you are at risk of type 2 diabetes and it’s important to talk to your doctor about it at your next visit. Type 2 diabetes can be prevented by leading a healthy lifestyle.
To learn more about your risks and what you can do about it please see the pre-diabetes fact sheet.
Generally your doctor will ask you to have an Oral Glucose Tolerance Test (OGTT), which is performed at a pathology laboratory and involved a blood sample being taken before and two hours after a glucose drink is consumed.
Approximately 2 million Australians are thought to have pre-diabetes and if left untreated may develop type 2 diabetes in the next 5 to 10 years.
Pre diabetes can affect your heart and blood vessels and ultimately increases the incidence of cardiovascular disease, which can lead to heart attack and stroke.
The steps taken to treat a pre-diabetes condition are the same as the steps taken to prevent it. This is done by making lifestyle changes to include regular physical activity and healthy eating.
