Are you at risk of type 2 diabetes?
An estimated 2 million Australians are at high risk of developing type 2 diabetes. Read on to find out about the risk factors, and changes you can make to reduce your risk.
Type 2 diabetes is a condition where the body can’t maintain a healthy blood glucose (sugar) levels, which can in turn lead to complications like heart and kidney disease. In Australia, more than 1.2 million people have been diagnosed with type 2 diabetes1, and it’s on the rise. In fact, it's thought 2 million Australians are at high risk of developing the condition2.
So what’s your risk of type 2 diabetes? Read on to understand your risk and what you can do to reduce your chances of developing the condition.
Type 2 diabetes risk factors
Your Type 2 diabetes risk is based on a range of factors – some that you can control and others that you can’t. Understanding your risk is important so you can take active steps to prevent the condition.
Risk factors that you can control include:
- Being an unhealthy weight: Being overweight, particularly carrying excess weight around your waistline (more than 80cm for women and more than 94cm for men).
- Being physically inactive: Regular physical activity helps your body to use insulin (the hormone responsible for regulating blood sugar levels), which is one of the reasons being inactive increases your risk.
- Smoking: Smoking increases your risk of type 2 diabetes.
- Having pre-diabetes: Pre-diabetes means your blood glucose levels are higher than normal, but not high enough to be type 2 diabetes. If you have pre-diabetes lifestyle changes like diet and exercise can prevent it from progressing to type 2 diabetes.
Risk factors you can’t control include:
- Age: Type 2 diabetes usually develops after the age of 45. However, young people are increasingly developing the condition. Almost 1 in 4 Australians over the age of 25 has diabetes or pre-diabetes3.
- Family history: Having a first degree relative, for example a parent, with type 2 diabetes means you have a genetic predisposition to the condition. It doesn’t necessarily mean you’ll get type 2 diabetes, but it does mean other lifestyle factors like being overweight can greatly increase your risk.
- Existing health conditions: Having existing health conditions like high cholesterol, high blood pressure, heart disease, polycystic ovarian syndrome, or having had gestational diabetes when pregnant increases your risk of developing type 2 diabetes. Those taking anti-psychotic medications are also at higher risk.
- Ethnicity: People from Middle Eastern, Asian (including Indian and Chinese backgrounds), Pacific Islander, Maori, North African or Southern European backgrounds may be more at risk.

How to reduce your risk of type 2 diabetes
Like many other health conditions, you can reduce your risk of type 2 diabetes by making healthy and informed choices. Here’s how.
Make healthy food choices
Eat lots of veggies and fruit every day, along with whole grains and lean proteins like lean chicken and fish. Cut back on foods with added-salt, sugar and fat. A good way to do that is to eat less processed foods and take away meals, and drink water instead of sugary drinks. Not only will eating healthy help control your blood glucose, it’s the most effective way to maintain a healthy weight.

Exercise helps your body to maintain healthy blood sugar levels. Try to work up to at least 30 minutes each day at an intensity where your heart rate goes up and your breathing gets harder, but you can still carry on a conversation.
A great way to stay motivated is to choose something you enjoy, like going for a ride with the family or joining a social exercise group like one of our Medibank Free + Active events around the country.
Aim for a healthy weight
If you’re overweight, even small amounts of weight loss can reduce your chance of developing diabetes. Talk to your doctor for specific advice.
The symptoms of type 2 diabetes are not always obvious. In fact, it’s thought that up to 500,000 Australians may be living with undiagnosed type 2 diabetes. And pre-diabetes has no symptoms at all. If you’re at high risk of developing the type 2 diabetes, ask your doctor about having a fasting blood glucose test. You can check your personal risk using the Diabetes Australia Risk Calculator.
If you smoke, one of the best things you can do for your health is to quit. But it’s not always easy. Speak to your doctor for help or call Quitline on 137 848.
