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 sugar in muscle, fat, and liver cells where it can be released
and used for energy when needed.
Diabetes develops if the body does not produce enough insulin or
does not use insulin properly.
