How Insulin Works
The role of insulin in the body is to allow blood sugar to move from your blood
stream into your cells. This gives your cells energy. But when you have diabetes,
your body doesn't make enough insulin and/or your body does not properly use
the insulin it makes.
Diabetes medicines can help; some help your body release more insulin or use
insulin more effectively. But as diabetes progresses, it can become harder for you
to control your blood sugar. When this happens, your doctor may suggest making changes
to your treatment plan. One of those changes may include choosing to add insulin
to your overall diabetes treatment plan, which may include diet, exercise, and other diabetes medicines.
