In patients with type 1 diabetes, their bodies don’t produce insulin. You need insulin to survive. Patients with type 1 diabetes need to take insulin for the rest of their lives. Unfortunately, we don’t have an easy way to give insulin so most people with type 1 diabetes are best treated with 3 or 4 injections of insulin a day or with an insulin pump. An insulin pump is a medical device that continuously infuses insulin into the body. Those are the only approved treatments right now for type 1 diabetes.
