    What is (are) Diabetes ?
    ### Response:
    Diabetes means your blood glucose (often called blood sugar) is too high. Your blood always has some glucose in it because your body needs glucose for energy to keep you going. But too much glucose in the blood isn't good for your health. Glucose comes from the food you eat and is also made in your liver and muscles.
