An estimated 30.3 million people in the United States had diabetes in 2015. Type 2 diabetes accounts for 90 to 95 percent of all diabetes cases.

In type 2 diabetes the body doesn't use insulin properly. Many people don't know they have type 2 diabetes because they don't display any symptoms. The late manifestation of the disease can cause major complications including lower limb amputation, late-stage kidney failure, heart attack, stroke and even death from high blood sugar.

The International Diabetes Federation says several risk factors have been associated with type 2 diabetes.

  • Family history of diabetes
  • Overweight
  • Unhealthy diet
  • Physical inactivity
  • Increasing age
  • High blood pressure
  • Ethnicity
  • Impaired glucose tolerance
  • History of gestational diabetes
  • Poor nutrition during pregnancy

The Centers for Disease Control and Prevention says type 2 diabetes may be reversible with diet and lifestyle changes.
