According to the Centers for Disease Control and Prevention, in 2020 there were an estimated 88 million adults, or 34.5% of the U.S. adult population, diagnosed with prediabetes. Prediabetes is a common condition where blood sugar levels are elevated but not yet high enough for a diabetes diagnosis. Many people don’t realize they have it. Simple lifestyle changes—like healthier eating, regular exercise, and weight management—can lower your risk of developing type 2 diabetes and related health complications.
