Prediabetes, also known as "impaired glucose tolerance," is a health condition that almost always, as the name suggests, precedes type 2 diabetes. More than 50 million people in the U.S. over age 20 have prediabetes with blood sugar levels that are higher than normal, but are not high enough to be classified as diabetes. More and more, doctors are recognizing the importance of diagnosing prediabetes as treatment of the condition may prevent more serious health problems, including type 2 diabetes and heart disease.
