Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high.
Over time, having too much glucose in your blood can cause health problems, such as heart disease, nerve damage, eye problems, and kidney disease.
Prediabetes means that your blood sugar is higher than normal but not high enough to be called diabetes. If you have #prediabetes, the long-term damage of diabetes—especially to your heart, blood vessels, eyes, and kidneys—may already be starting.
If you have prediabetes or any other risk factors for type 2 diabetes (including being overweight), talk with your doctor about your personal lifestyle including diet and exercise and possibly taking medicine to prevent or delay type 2 diabetes.
