THE INSULIN

Insulin is a hormone made in our pancreas. It allows our body to use glucose for energy.

Frederick Banting and his friends discovered the hormone insulin in 1920. It helps balance our blood glucose levels. When there is too much glucose in our bloodstream, insulin signals our body to store the excess in our liver. The stored glucose isn't released until our blood glucose levels decrease.

Diabete occurs when our body doesn't use insulin properly or doesn't make enough insulin. There are two types of diabetes. So, injections of insulin can help both types of diabetes. All types of insulin produce the same effects. The composition of different types affects how fast and long they work to help the natural increases and decreases of insulin levels. 

The insulin is one of the most important medical discoveries. Before it, diabetes meant a slow and sure death.
