If you have Type 1 diabetes, your body doesn't make insulin which helps sugar from food be turned into energy. If you have Type 2 diabetes, your pancreas does not make enough insulin and your body can't use it properly. Sometimes, eating a healthy diet and getting enough exercise will control Type 2 Diabetes. Sometimes, your doctor will give you medication. However, diabetes medications that lower blood sugar never, never take the place of healthy eating and exercise. Some people, after a few years of taking oral medication, will need to begin taking insulin.
