What is pre-diabetes?

If your blood glucose level is higher than normal but not high enough to be diagnosed as type 2 diabetes, you may have a condition called pre-diabetes. This means your body’s insulin is not working effectively.

Pre-diabetes is also known as impaired glucose tolerance, impaired fasting glucose or insulin resistance. It’s estimated that two million Australians are currently living with pre-diabetes.

What are the risks associated with pre-diabetes?

Pre-diabetes can increase your risk of cardiovascular (heart and blood vessel) disease, which can lead to heart attack and stroke.

Left untreated, pre-diabetes can develop into type 2 diabetes within five to 10 years. However, leading a healthy lifestyle can help you manage pre-diabetes and reduce your risk of developing type 2 diabetes – so the earlier you find out, the better.


Pre-diabetes is diagnosed with an oral glucose tolerance test (OGTT). Your doctor can order this simple test and you can have it at a pathology laboratory. If you think you may be at risk of pre-diabetes, talk to your doctor about it as soon as possible.
