Learn more about diabetes with Kay Moua, ARNP with The Everett Clinic. When a person has diabetes, their pancreas is no longer producing the amount of insulin that your body requires. The sooner you go on insulin, the sooner you are helping your body out. For some patients, the fear of going on insulin can prevent them from seeking help. The goal is to help patients get comfortable with each step of starting insulin. The sooner a patient starts on insulin, the better outcome they will have.
