How common is prediabetes?

The CDC estimates that as many as 57 million Americans aged 20 or older have prediabetes. That's based on national statistics of people who have been diagnosed with impaired fasting glucose.

Prediabetes should not be ignored. It signals the likely onset of a more serious condition, and it can begin the process of doing damage to your heart and possibly other organs such as the kidneys, eyes, and nervous system.
