Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been released.
Insulin is a hormone, normally produced in sufficient amounts by the healthy human pancreas. Its role is to facilitate the final digestion of glucose by the human body. When insulin is lacking (diabetes), glucose remains undigested in the blood. The body isn't being fed, and the high blood sugar can cause damage, the ramifications of diabetes. The two major types of diabetes (type 1 and type 2, IDDM and NIDDM) are separated by presence of insulin.
