When someone has type 1 diabetes, there is no question that they will need insulin. Having type 1 means their pancreas can no longer make insulin, and it must be injected to help them survive.

Type 2 diabetes is different. People with type 2 still produce insulin on their own, but their body is resistant to it. Only about one-third of type 2 people are prescribed insulin. How do doctors decide when a person with type 2 should be on insulin? Could earlier insulin treatment help matters in the long run, and perhaps reduce devastating complications? Does the thought of injecting insulin make you nervous?
