People with pre-diabetes have higher than normal BGLs, but they are not high enough for a diagnosis of type 2 diabetes. This means your body’s insulin is not working effectively.
Two conditions fit into pre-diabetes; impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). Having either of these conditions does not necessarily mean a progression to type 2 diabetes but the risk is increased. If lifestyle changes are not made, pre-diabetes can develop into type 2 diabetes within 5 to 10 years.
If you think you may be at risk of pre-diabetes, it’s important to talk to your GP about it at your next visit. Pre-diabetes is diagnosed with an oral glucose tolerance test (OGTT). Your GP can order this blood test and you can have it at a pathology laboratory.
If you have pre-diabetes you also have a higher risk of developing cardiovascular disease. Therefore, it is important to have your blood pressure and cholesterol levels checked regularly.
There is evidence that people with pre-diabetes can delay or prevent the progression to type 2 diabetes. This includes making healthy lifestyle changes, not smoking and losing 5 – 10% of your body weight if you are overweight.
