People with type 1 diabetes will need to inject insulin to fulfill the requirement of the body’s lack of insulin.



Insulin and Type 2 Diabetes


Type 2 diabetes is characterized by the body when the body is not responding successfully to insulin. This is called insulin resistance. Resulting, the body is not completely capable to take up glucose from the blood. In the earlier stages of type 2 diabetes, the body responds by producing more insulin which would normally need by the body.


If type 2 diabetes progress over a number of years, the excess demands on the pancreas to make insulin which can lead to a loss of insulin-producing cells also called pancreatic beta cells as they wear out.
