Prediabetes risk factors

Mature doctor explaining to patient

People can have prediabetes for years but have no clear symptoms. That's why it often goes undetected until serious health problems show up.

Prediabetes risk factors include:

  • Weight
    The more fat you have, the more serious your risk. And the risk is even higher if that extra weight is mostly around your stomach, particularly if you are:
    A man whose waist circumference is more than 40 inches

To see if you are overweight or obese, calculate your Body Mass Index.
  • Inactivity
    Being physically active less than 3 times per week increases your risk of prediabetes.
  • Age
    You can get prediabetes at any age. But the risk goes up as you get older, especially if you are older than 45.
  • Family history
    Your risk is higher if your parent, brother, or sister has type 2 diabetes.
  • Race
    Rates amongst high-risk ethnicities diagnosed with diabetes are as follows:1
    American Indians/Alaskan Natives (15.9%)
    Non-Hispanic blacks (13.2%)
    Hispanic/Latinos (12.8%)
    Asian-Americans (9.0%)
    Hispanic/Latinos (12.8%)
  • Gestational diabetes
    If you had gestational diabetes when you were pregnant, or if your baby weighed more than 9 pounds, you have a higher risk of prediabetes.

If you think you might have prediabetes, take the prediabetes quiz and talk to your doctor. Your doctor might ask you to take a simple blood test. It’s the only way to confirm you have prediabetes.
