Diabetes is one of the most common and costly chronic diseases in the United States, affecting millions of people each year. Over time, high blood sugar can lead to serious health complications involving the heart, kidneys, eyes, nerves, and blood vessels. The condition can affect people of all ages and backgrounds, and its prevalence continues to grow across the country.
About 38.4 million Americans — roughly 11.6% of the population — live with diabetes. Of those, an estimated 29.7 million have been diagnosed, while 8.7 million remain undiagnosed. Additionally, more than 97 million U.S. adults — about one in three — have prediabetes, and most are unaware of it.
The good news is that type 2 diabetes and prediabetes are largely preventable. Maintaining a healthy weight, eating balanced meals rich in vegetables, whole grains, lean proteins, and healthy fats, and engaging in regular physical activity can significantly reduce the risk. Avoiding smoking, limiting alcohol, managing stress, and getting regular checkups for blood sugar, blood pressure, and cholesterol are all key components of prevention.
