Prediabetes means you have a higher than normal blood sugar level. It's not high enough to be considered type 2 diabetes yet, but without lifestyle changes, adults and children with prediabetes are more likely to develop type 2 diabetes.
If you have prediabetes, the long-term damage of diabetes — especially to your heart, blood vessels, and kidneys — may already be starting. There's good news, however. Progression from prediabetes to type 2 diabetes isn't inevitable.
Eating healthy foods, making physical activity part of your daily routine, and staying at a healthy weight can help bring your blood sugar level back to normal.
