Diabetes Symptoms and Statistics
Diabetes often goes undiagnosed because many of its symptoms seem so harmless. Recent studies indicate that the early detection of diabetes symptoms and treatment can decrease the chance of developing the complications of diabetes. If you have one or more of these diabetes symptoms, see your doctor right away.

From the 2011 National Diabetes Fact Sheet (released Jan. 26, 2011)
Total prevalence of diabetes
Total: 25.8 million children and adults in the United States—8.3% of the population—have diabetes.
Diagnosed: 18.8 million people
Undiagnosed: 7.0 million people
Prediabetes: 79 million people*
New Cases: 1.9 million new cases of diabetes are diagnosed in people aged 20 years and older in 2010.
* In contrast to the 2007 National Diabetes Fact Sheet, which used fasting glucose data to estimate undiagnosed diabetes and prediabetes, the 2011 National Diabetes Fact Sheet uses both fasting glucose and A1C levels to derive estimates for undiagnosed diabetes and prediabetes. These tests were chosen because they are most frequently used in clinical practice.
