Prediabetes and Prevention

What is Prediabetes?

Prediabetes is where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as type 2 diabetes.

Prediabetes puts you at increased risk of developing type 2 diabetes, heart disease, and stroke.

Risk Factors

You’re at risk for type 2 diabetes if you:

  • Are overweight
  • Are 45 years or older
  • Have a parent or sibling with type 2 diabetes
  • Are physically active less than 3 times a week
  • Have had gestational diabetes or given birth to a baby who weighed more than 9 pounds
  • Are an African American, Hispanic or Latino, American Indian, or Alaska Native person. Some Pacific Islander and Asian American people are also at higher risk.

Signs & Symptoms

You can have prediabetes for years without noticeable symptoms. It often goes undetected until serious health problems such as type 2 diabetes show up.

Talk to your provider about getting your blood sugar tested if you have any of the risk factors for prediabetes.


You can get a simple blood sugar test to find out if you have prediabetes. Ask your provider if you should be tested.

Preventing Type 2 Diabetes

If you have prediabetes, you can lower your risk for developing type 2 diabetes.

Lower your risk by:

  • Losing a small amount of weight if you’re overweight - around 5% to 7% of your body weight
  • Getting regular physical activity - at least 150 minutes a week of brisk walking or a similar activity.

Get support in making those changes through the CDC-led National Diabetes Prevention Program.
