The Centers for Disease Control and Prevention (CDC) estimates that 1 of every 3 US adults had prediabetes in 2010. That is 79 million Americans aged 20 years or older. The vast majority of people living with prediabetes do not know they have it. A person with prediabetes has a blood sugar level higher than normal, but not high enough for a diagnosis of diabetes.
Prediabetes is a serious health condition that increases the risk of developing type 2 diabetes, heart disease, and stroke.
• 79 million Americans—35% of adults aged 20 years and older—have prediabetes.
• Half of all Americans aged 65 years and older have prediabetes.
