The Basics
Diabetes is a disease. When you have diabetes, there is too much sugar or glucose in your blood.
How Does Diabetes Work?
The food you eat is turned into glucose. Glucose is the main source of energy for your body. Glucose is carried to other parts of the body through your blood.
When you have diabetes, your body has trouble turning glucose into energy. Instead of being used by your body, the glucose builds up in your blood. The rest of your body is starved of energy.
