A person with prediabetes has a blood sugar level higher than normal, but not high enough for a diagnosis of diabetes. He or she is at higher risk for developing Type 2 diabetes and other serious health problems, including heart disease, and stroke. Without lifestyle changes to improve their health, 15% to 30% of people with prediabetes will develop Type 2 diabetes within five years. Review our Prediabetes in Utah Fact Sheet (PDF) for more information.
- prediabetes is sometimes called impaired glucose tolerance (IGT) or impaired fasting glucose (IFG).
- About one in 14 (7.1%) of adults in the U.S. have been told by a health care provider that they have prediabetes. About one-third of Americans aged 20 and over are at high risk for Type 2 diabetes.

|A1C||5.7% – 6.4%|
|Fasting blood glucose||Between 100 – 125 mg/dL|
|Oral Glucose Tolerance Test (OGTT) 2 hour blood glucose||140 mg/dL – 199 mg/dL|
- Being overweight
- Not getting enough physical activity
- Getting older
- Family history of Type 2 diabetes
- Membership in a racial or ethnic minority group
- Polycystic ovarian syndrome
- Sleeping too much or too little
- Having metabolic syndrome (high blood pressure, high blood sugar and high cholesterol) or having even one of these symptoms
- Having history of gestational diabetes or delivering a baby weighing 9 pounds or more
Preventing Type 2 Diabetes
Research shows that you can lower your risk for Type 2 diabetes by 58% by:
- Losing 7% of your body weight (or 15 pounds if you weigh 200 pounds)
- Exercising moderately (such as brisk walking) 30 minutes a day, five days a week
Don't worry if you can't get to your ideal body weight. Losing even 10 to 15 pounds can make a difference. Intersted in learning more about improving self-management skills? Check out information you we have for the evidence-based lifestyle change program, National Diabetes Prevention Program.
