Two adults and two children

Prediabetes happens when your blood sugar levels are consistently higher than normal. It's a serious condition that can lead to type 2 diabetes and damage your health, especially your heart. It's also your last opportunity to prevent type 2 diabetes. That's because prediabetes is much easier to reverse than type 2 diabetes. It only takes a few lifestyle changes to reduce your risk and lower your blood sugar levels.

Prediabetes is more common than most people think. Its effects are serious, but the symptoms can go undetected for years. Unfortunately, that means most of the 88 million people living with prediabetes don't know they have it. If they knew, they'd want to change it. So don't wait to find out if you're at risk. Take the one-minute risk test now.

Who is at Risk?

More than 4 out of 5 of people who have prediabetes don't know they have it, which means you or someone you know may already be at risk for dangerous health consequences like type 2 diabetes, heart disease, and stroke. Prediabetes doesn't always show signs or symptoms, which is why it's important to know the risks.

Know the Risks

If you have one or more of these characteristics, you may be at higher risk than others for developing prediabetes, and eventually, type 2 diabetes:

  • Being overweight
  • Being 45 or older
  • Having a parent, brother, or sister with type 2 diabetes
  • Physically active less than three times per week
  • Ever having gestational diabetes or giving birth to a baby who weighed more than 9 pounds
  • Having polycystic ovary syndrome
  • Having high blood pressure
  • Being a man
  • Belonging to certain racial or ethnic groups, including African American, Latinx American, American Indian, Pacific Islander, and some Asian American communities.
