Do I really need to be on insulin?

Since it's possible for some people with Type 2 diabetes to live their whole life without taking insulin, it's only natural to ask yourself "Do I really need this?" But if your doctor has put you on insulin, you do need it. Insulin is a hormone that helps your body take glucose from food and use it for energy. Type 2 diabetes is really two problems-your body doesn't produce enough insulin to keep your blood glucose at normal levels, and your body can't effectively use the insulin it does produce. The result is high blood glucose. Some people with Type 2 diabetes can keep blood glucose at a safe level with diet and exercise, but most people require medication.
