Insulin and diabetes

  • Insulin is a hormone made by special cells in the pancreas.
  • Absorption of insulin varies depending on the part of the body into which you inject.
  • It is recommended that the needle be changed with each injection.

Insulin injections are required when the body produces little or no insulin, as with type 1 diabetes. They are also required for some people with type 2 diabetes when diabetes tablets, together with healthy eating and regular physical activity, are not enough to control blood glucose levels.
