Diabetes Statistics

What is Diabetes?

Diabetes is a disease that leads to high levels of blood sugar (glucose). It happens when the body does not make any or enough insulin, or does not use insulin well. Diabetes can lead to serious health problems, but people with diabetes can take steps to manage the disease and lower the chance of health problems.

You may have wondered if you are at risk for developing diabetes, or you may have been told you have prediabetes. If so, you should know that diabetes prevention is proven, possible, and powerful. Studies show that people at high risk for type 2 diabetes can prevent or delay the onset of the disease.
