(KUTV) One in three people have prediabetes and about 90 percent don't know it.

How do you know if you have prediabetes and what can you do to prevent it? Take this quick prediabetes quiz here:

Dr. Liz Joy, MD, MPH, the medical director of Community Health and Clinical Nutrition at Intermountain Healthcare explains:

  • Estimated that more than 86 million American adults have prediabetes (that's 1 in 3), and 90% of them don't know they have it
  • Anybody can take the online screening test. People with a score of 5 or higher, or women with a history of gestational diabetes during pregnancy should have a blood test to confirm if they have prediabetes
  • Type 2 diabetes can be prevented! Prevention programs have been shown to reduce the likelihood of developing type 2 diabetes by nearly 60% at 2 years. A 10% weight loss from baseline (20 lbs for a 200 lb person) is associated with an 85% decreased risk of developing type 2 diabetes
  • Key lifestyle changes include dietary changes in support of weight loss and regular exercise - at least 150 minutes per week (about 30 min per day 5 days per week) of moderate intensity physical activity - like a brisk walk
