By Mayo Clinic staffPrediabetes means that your blood sugar level is higher than normal, but it's not yet high enough to be classified as type 2 diabetes. Still, without intervention, prediabetes is likely to become type 2 diabetes in 10 years or less. And, if you have prediabetes, the long-term damage of diabetes — especially to your heart and circulatory system — may already be starting.
There's good news, however. Prediabetes can be an opportunity for you to improve your health, because progression from prediabetes to type 2 diabetes isn't inevitable. With healthy lifestyle changes — such as eating healthy foods, including physical activity in your daily routine and maintaining a healthy weight — you may be able to bring your blood sugar level back to normal.
