What is Diabetes?
Diabetes is a group of diseases marked by high levels of blood glucose resulting from defects in insulin production, insulin action, or both. Diabetes can lead to serious complications and premature death, but people with diabetes can take steps to control the disease and lower the risk of complications.
What is the prevalence of diabetes by type?
Type 1 (previously called insulin-dependent or juvenile-onset) diabetes accounts for approximately 5 percent of all diagnosed cases of diabetes in adults.
Type 2 (previously called non-insulin-dependent or adult-onset) diabetes accounts for 90 to 95 percent of all diagnosed cases of diabetes in adults. Type 2 diabetes is increasingly being diagnosed in children and adolescents.
Gestational diabetes occurs in 2 to 10 percent of pregnancies. Women who have had gestational diabetes have a 35 to 60 percent chance of developing diabetes, mostly type 2, in the next 10 to 20 years.
Prediabetes : A Risk Factor for Type 2 Diabetes. People with prediabetes have blood glucose levels that are higher than normal, but not high enough to be diagnosed as diabetes. Unfortunately, prediabetes can put people at increased risk of developing type 2 diabetes, heart disease, and stroke.
Although about 33% of U.S. adults have prediabetes awareness of this risk condition is low. Less than 10% of U.S. adults with prediabetes report that they have ever been told that they have prediabetes. Progression to type 2 diabetes among those with prediabetes is not inevitable.
Studies have shown that people with prediabetes can prevent or delay the onset of type 2 diabetes by losing 5%–7% of their body weight and getting at least 150 minutes per week of moderate physical activity. Because awareness of prediabetes is low, we anticipate that the percentage of people who are aware that they have prediabetes will rise as diabetes prevention efforts progress.
