Insulin therapy is often an important part of diabetes treatment. Understand the key role insulin plays in managing your blood sugar, and the goals of insulin therapy. What you learn can help you prevent diabetes complications.
It may be easier to understand the importance of insulin therapy if you understand how insulin normally works in the body and what happens when you have diabetes.
If your pancreas secretes little or no insulin (type 1 diabetes), or your body doesn't produce enough insulin or has become resistant to insulin's action (type 2 diabetes), the level of glucose in your bloodstream increases because it's unable to enter cells. Left untreated, high blood glucose can lead to complications such as blindness, nerve damage (neuropathy) and kidney damage.
