In this section you have learnt in detail about the key physiological processes involved in regulating blood glucose concentrations in healthy individuals, and how lack of insulin or insulin resistance changes how glucose homeostasis operates in people with type 1 and type 2 diabetes.

Use of replacement insulin in type 1 diabetes and in some people with type 2 diabetes allows restoration of these physiological processes, controlling blood glucose concentrations and reducing the risk of long term complications.
