Prediabetes FAQs


What is prediabetes?

Prediabetes is a condition where your blood sugar level is higher than normal, but not yet high enough to be classified as having type 2 diabetes. While persons in this situation do not have diabetes, it is still a dangerous condition. Without intervention, prediabetes is likely to become type 2 diabetes within 10 years.

If you have prediabetes you have a greater risk of heart disease and stroke. In addition, prediabetes will also increase your chance of having other health problems, such as heart disease and vision problems (retinopathy). Prediabetes is a warning sign to take action!

How do I know if I have prediabetes?

Prediabetes usually does not have any symptoms, so it is very important for you to see your doctor. A simple blood test can be done to determine if you have prediabetes. There are three common types of tests used to determine if you have diabetes:

Prediabetes tests*

Blood glucose (sugar) test Prediabetes blood sugar level Normal blood sugar level
Fasting blood glucose 100 mg/dl to 125 mg/dl Less than 100 mg/dl
2-hour oral glucose tolerance test (75 g) 140 mg/dl to 199 mg/dl Less than 140 mg/dl
Hemoglobin A1C 5.7% to 6.4% Less than 5.7%

*If you have blood sugar levels higher than the prediabetes level, your doctor will talk to you about diabetes.

What is the treatment for prediabetes?

There are research studies that show lifestyle changes can actually delay or prevent diabetes. In 2002, the Diabetes Prevention Program (DPP) was a landmark study sponsored by the National Institutes of Health. The results of this study found that the combination of 30 minutes of physical activity five days a week or 150 minutes per week and a 7 percent reduction in body weight led to a 58 percent reduction in diabetes.
