What is Prediabetes?

Prediabetes occurs when blood sugar (glucose) levels are higher than normal, but not high enough to be diabetes.  Prediabetes may be called borderline diabetes, impaired fasting glucose, or impaired glucose tolerance.

People with prediabetes are at high risk of developing type 2 diabetes, heart disease, and stroke.  Between 15-30% of people with prediabetes will develop type 2 diabetes within 5 years.  However, not everyone with prediabetes will develop type 2 diabetes.

People with prediabetes can develop health problems usually associated with diabetes.  These include early kinds of kidney disease, nerve damage, and damaged blood vessels.  The risk of stroke is also higher in people with prediabetes.

Around 1 in 3 (35 percent) of American adults have prediabetes. Using this number, as many as 1.4 million adult Minnesotans may have prediabetes.  In 2011, only 6 percent of adults in Minnesota (approximately 210,000) said their health care provider told them they had prediabetes, which suggests that most Minnesotans with prediabetes do not know they have it.
