Yes, and there are several possible reasons. First, the threshold for diagnosing diabetes was lowered in 1997 by the American Diabetes Association. This was done because research showed that having an even slightly elevated blood sugar can cause damage to both small and large blood vessels. Second, our lifestyles have changed dramatically over the past twenty to thirty years. We are eating larger portions and more processed foods. Also, many Americans do very little physical activity. As a result, there are more overweight and obese people. Being overweight/obese is a risk factor for Type 2 diabetes.
