Prediabetes

Overview

Prediabetes means blood sugar levels are higher than normal but not yet high enough for a diabetes diagnosis. It's a warning sign — and an opportunity, since progression to type 2 diabetes can often be prevented or delayed.

Symptoms

Usually none. Prediabetes is typically picked up through routine blood testing rather than symptoms.

Risk Factors

Overweight or obesity (especially around the abdomen), physical inactivity, family history of type 2 diabetes, older age, and a history of gestational diabetes.

Common Blood Tests

Fasting plasma glucose, HbA1c (average blood sugar over roughly three months), or an oral glucose tolerance test are used to diagnose prediabetes.

Lifestyle Information

Weight loss (even modest amounts), regular physical activity, and dietary changes — reducing refined carbohydrates and sugary drinks, increasing fibre — are proven to reduce progression to type 2 diabetes.

When to seek medical advice

If you're told you have prediabetes, it's worth discussing a structured plan with your doctor, since early lifestyle changes are most effective at this stage.
