Quick answer
What are prediabetes?
Prediabetes means blood glucose is above the usual range but not in the diabetes range. It increases the chance of developing type 2 diabetes and cardiovascular disease, but sustainable changes to weight, food and activity can substantially reduce risk. It usually causes no symptoms.
What the result means
Prediabetes is not an inevitable step toward diabetes. HbA1c can be affected by some blood conditions, pregnancy and other factors, so results require context.
Changes that help
Aim for changes you can sustain: more fibre-rich foods, fewer sugary drinks, regular movement, strength activity and gradual weight loss if recommended. Avoid crash diets.
Follow-up
Monitoring identifies whether glucose is improving, stable or entering the diabetes range. Blood pressure, cholesterol and smoking are also important cardiovascular risks.
Common questions about prediabetes
- Can prediabetes go back to the normal range?
- Yes. Weight loss where appropriate, regular activity and dietary changes can return glucose to a lower range, although ongoing monitoring remains important.
- Do I need medicine for prediabetes?
- Lifestyle support is usually first-line. Medicine may be considered for some higher-risk people after individual assessment.
- How often should HbA1c be repeated?
- Timing depends on the result and your risk factors. The clinician who arranged the test should give a follow-up plan.
