Insulin

Insulin is a hormone produced in the pancreas that allows sugar (glucose) to enter body cells, where it is used for energy. It also helps the body store extra energy in muscle, fat, and liver cells.

Diabetes develops if the body does not produce enough insulin, does not use insulin properly, or both.
