    ### Response:
    Prediabetes means you have blood glucose, or blood sugar, levels that are higher than normal but not high enough to be called diabetes. Glucose comes from the foods you eat. Too much glucose in your blood can damage your body over time. If you have prediabetes, you are more likely to develop type 2 diabetes, heart disease, and stroke.
