Prediabetes can develop into diabetes, a very dangerous and harmful disease.


Diabetes is a serious condition that causes blood sugar levels to rise higher than normal. Type 2 diabetes is the most common form of diabetes. Currently, diabetes affects more than 29 million people.

Prediabetes occurs when blood sugar levels are higher than normal but not high enough for a type 2 diabetes diagnosis. Risk for developing type 2 diabetes may be reduced or eliminated by weight loss, healthier eating and increased physical activity. More than 86 million Americans have prediabetes and are at risk of developing diabetes.

Prediabetes may be reversible; diabetes has no cure.

Chances are you know at least one person with diabetes and the likelihood that you know one of the 86 million Americans with prediabetes is even greater. Only about 9 million people know they have prediabetes, a potentially reversible condition.

Diabetes Facts

The Centers for Disease Control and Prevention (CDC) have been involved in extensive research on prediabetes and diabetes in the United States. Their findings suggest that this disease continues to be a growing issue for people of all ages and backgrounds:

  • Diabetes affects 25.8 million people in the United States.
  • Recent studies estimate that 79 million Americans over the ages of 20 have prediabetes.
  • Diabetes is the seventh leading cause of death in the United States.
  • In 2010, roughly 1.9 million new cases of diabetes in people over the age of 20 were diagnosed.
  • People with diabetes are about 50% more likely to die than people of the same age without diabetes.
  • Medical expenses for people with diabetes are 2.3 times greater than those without.
  • People with diabetes are between 2-4 times more likely to have a stroke and die from heart disease.
  • Diabetes is the leading cause of new cases of blindness in people aged 20-74.
  • People with diabetes are at greater risk for nerve damage, dental disease, lower limb amputation, depression and complications during pregnancy.

Diabetes Demographics

The percentage of U.S. adults aged 20 years or older with prediabetes in 2009-2012 was similar for non-Hispanic whites (35%), African Americans (39%), and Hispanic/Latinos (38%).

Cases of diabetes in the U.S., 2010-2012
7.6%   Non-Hispanic whites
9.0%   Asian American
12.8%   Hispanic/Latino
13.2%   African American
15.9%   American Indian/Alaska Natives

Over half (51%) of all Americans with prediabetes are aged 65 or older. Nearly 40% of adults with diabetes are 65 years or older.

Total: By age:
20 years or older   28.9 million
20-44   4.3 million
45-64   13.4 million
65 years or older   11.2 million
