When your body doesn't make enough insulin, or it can't effectively use the insulin it does produce, your doctor may prescribe insulin therapy. All people with type 1 diabetes, many people with type 2 diabetes, and some women with gestational diabetes need to inject themselves with insulin one or more times every day.

An insulin therapy regimen includes the types of insulin you take, when you take them and how much you take. There are a wide variety of excellent therapy regimens. The one that your doctor prescribes may not fit exactly into the categories you see here.
