If you are diagnosed with diabetes, it means that your body either does not make enough insulin or cannot use the insulin it makes.

Blood sugar, or glucose, is the main sugar found in your blood. It comes from the food you eat and is your body’s essential and main source of energy.

But if you have too much blood sugar in the blood, it eventually can cause serious health problems such as heart disease, vision loss, kidney failure, nerve damage, circulation problem of the leg, and eventual loss of a leg.
