What should you know about type 2 diabetes prevention?

Risk reflects several influences, including family history, age, previous high glucose, pregnancy-related diabetes, body weight, blood pressure and activity patterns. Some factors cannot be changed, but daily habits and regular medical checks can still make a meaningful difference. Prediabetes means glucose is above the usual range but does not meet the threshold for diabetes; it is a useful time to review risk.

Prevention is not a test of willpower. A clinician can help choose realistic changes and consider conditions such as obesity, sleep problems or medicines that affect glucose.

Build meals around vegetables, pulses, whole grains, protein and unsweetened drinks, while reducing frequent sugary drinks and highly processed snacks. Add regular movement that fits your routine, such as walking, active commuting or resistance exercise. Protect sleep, address stress, and choose one change to practise before adding another.

If you have risk factors or a history of prediabetes, ask about glucose testing and follow-up. Keep a record of blood pressure, medicines and relevant family history so your clinician can interpret your risk accurately.

Arrange a medical review for persistent thirst, frequent urination, unexplained weight change, blurred vision or unusual tiredness. Seek urgent care for vomiting with dehydration, confusion, severe drowsiness or difficulty breathing. A new wound with spreading redness or fever also needs prompt assessment, especially when glucose may be high.

Ask whether you need a glucose test, how often it should be repeated, which changes fit your health, and whether blood pressure or cholesterol also need attention. Discuss family history, pregnancy history, sleep and medicines rather than focusing on weight alone.
