Insulin
Insulin is a hormone that lowers the level of glucose (a type of sugar) in
the blood. It's made by the beta cells
of the pancreas and released into the blood when the glucose level goes up, such as
after eating. Insulin helps glucose enter the body's cells, where it can be used for
energy or stored for future use. In diabetes, the pancreas doesn't make enough insulin
or the body can't respond normally to the insulin that is made. This causes the glucose
level in the blood to rise.
