In Type 1, the pancreas stops making insulin, a blood sugar-regulating hormone that helps the body convert sugar in food into energy. Treatment is lifetime replacement insulin, usually via injections or a small pump. In Type 2, the body can't make proper use of insulin. It can sometimes be treated with a healthy diet and exercise.
