    Intermountain Registered Dietitians of Intermountain Healthcare answered:
    If you have type 2 diabetes, your body's cells have become resistant to insulin. So even though you have an insulin "key," it's as if the cell "lock" is broken so that glucose can't easily get in. (Insulin allows glucose to cross out of your bloodstream and go into your body's cells -- it's like a key that "unlocks" the cells.) Glucose stays in your bloodstream and blood glucose gets too high. Over time, some people with type 2 diabetes also develop trouble making enough insulin (insulin deficiency). This is the same problem that people with type 1 diabetes have.
