Diabetes is a group of diseases marked by high levels of blood glucose resulting from problems in how insulin is produced, how insulin works, or both. People with diabetes may develop serious complications such as heart disease, stroke, kidney failure, blindness, leg amputations, and premature death. Diabetes can be treated and managed by healthful eating, regular physical activity, and medications to lower blood glucose levels.
Prediabetes is when someone has a blood sugar level higher than normal, but not high enough for a diagnosis of diabetes. People with prediabetes have an increased risk of developing type 2 diabetes, heart disease and stroke. Without lifestyle changes to improve their health, 15% to 30% of people with prediabetes will develop type 2 diabetes within 5 years (CDC) .
