Prediabetes means blood glucose levels are higher than the usual range but do not meet the diagnostic threshold for diabetes. It may not cause obvious symptoms, so appropriate testing is important for people with risk factors. Prediabetes does not mean that diabetes is inevitable: a clinician can help assess individual risk and discuss steps that may support metabolic health.
Who may have a higher risk?
Risk can be influenced by family history of type 2 diabetes, excess abdominal fat, limited physical activity, a history of gestational diabetes and some other health conditions. Risk varies between individuals, and appearance or symptoms alone cannot establish whether someone has prediabetes.
Which tests are used?
Healthcare professionals may use a fasting blood glucose test, HbA1c or an oral glucose tolerance test, depending on the situation. The interpretation depends on the test, clinical context and applicable guidelines. Ask a clinician which test is appropriate and whether repeat testing is needed.
Practical steps to discuss with your clinician
- Build meals around vegetables, pulses, whole grains and other minimally processed foods where practical.
- Choose regular physical activity that suits your ability and health status.
- Work toward a sustainable weight-management plan if recommended; avoid crash diets and unverified supplements.
- Prioritise sleep and ask for support with smoking cessation if relevant.
- Attend follow-up appointments and repeat testing when advised.
Can prediabetes be reversed?
Some people can return their blood glucose to a healthier range through sustained lifestyle changes and, when appropriate, medical treatment. Results differ, and continued monitoring may still be needed. Avoid products that promise a guaranteed cure.
Frequently asked questions
Can prediabetes have symptoms?
Often it has no clear symptoms, which is one reason testing may be useful for people at increased risk.
Should I stop eating all carbohydrates?
Not necessarily. Food choices and portions should be individualised; discuss a balanced eating plan with a qualified professional.
