Insulin Resistance (IR) is a condition in which the cells of the body become resistant to the effects of insulin. Thus, a person is said to have impaired glucose tolerance / pre-diabetes. IR results in higher levels of insulin being required to maintain normal blood glucose levels. Eventually, the pancreas may be unable to keep up with insulin demand leading to long term health issues.
1 in 4 adults in Australia may at some time in their life have impaired glucose tolerance
Being diagnosed with impaired glucose tolerance does not necessarily mean you will develop diabetes, but it makes you 10-20 times more likely than a normal person
It is estimated that up to 1.8 million Australians are living with diabetes / impaired glucose tolerance
Who is at Risk of Developing Insulin Resistance? Patients who - 
Are overweight / obese
Are Aboriginal or Torres Strait Islanders
Have a high fat diet
Have a family history of type 2 diabetes, hypertension or heart disease
