Key points
- Certain factors increase your risk for prediabetes and type 2 diabetes.
- Type 2 diabetes is common, is serious, and with lifestyle changes can be prevented or delayed.
- The National Diabetes Prevention Program (National DPP) lifestyle change program can help.
What are prediabetes and diabetes?
Having prediabetes means your blood glucose (sugar) levels are higher than normal, but not high enough to be diagnosed as diabetes. Prediabetes can lead to heart disease, stroke, and type 2 diabetes, the most common form of diabetes. Prediabetes can often be reversed.
Take the test
In the United States, about 1 in 3 adults has prediabetes, and more than 8 in 10 of them don't know they have it. Without taking action, many people with prediabetes could develop type 2 diabetes within 5 years.
With type 2 diabetes, your body can't effectively use insulin (a hormone that helps glucose get into the cells of the body). You can get type 2 diabetes at any age, but certain factors increase your risk.
Prevention
If you have prediabetes, the National DPP lifestyle change program is one of the most effective ways to prevent type 2 diabetes. In the program, you'll learn skills to help you lose weight, become more active, and improve your overall health.
Type 2 diabetes has serious consequences
Diabetes is serious
Diabetes increases the risk of serious health problems, including:
- Heart attack
- Stroke
- Blindness
- Kidney failure
- Loss of toes, feet, or legs
Diabetes is costly
In 2022, the total cost of care for people with diagnosed diabetes was $413 billion. About 1 in 4 health care dollars is spent on people with diagnosed diabetes. Most expenses are related to hospitalizations and medicines used to treat diabetes complications.
