Prediabetes Basics

Prediabetes by the Numbers

What is Prediabetes?

Prediabetes means your blood glucose (sugar) is higher than normal, but not high enough to be diagnosed with diabetes. Over time, high blood glucose damages the body. Prediabetes is a warning sign! Ignoring this warning sign may result in type 2 diabetes, which leads to serious health issues:

Lifestyle changes are the key to keeping prediabetes from developing into a diagnosis of full-blown type 2 diabetes. 

What is Type 2 Diabetes?

Type 2 diabetes is the most common form of diabetes. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have type 2 diabetes, your body can't use its own insulin as well as it should. This causes sugar to build up in your blood.

Am I At Risk?

You are at increased risk for developing prediabetes and type 2 diabetes if you:

  • Are overweight; 
  • Are 45 years of age or older;
  • Have a parent or sibling that has type 2 diabetes;
  • Are physically active less than three times per week; 
  • Ever gave birth to a baby that weighed more than 9 pounds;
  • Ever had diabetes while pregnant (gestational diabetes)

Race and ethnicity also affect your risk. African Americans, Hispanic/Latino Americans, American Indians, Pacific Islanders, and some Asian Americans are at particularly high risk for type 2 diabetes.
