If you have Type I Diabetes, you will need insulin to manage your blood sugar levels. There are several types of insulin available. Insulin can be delivered by syring injection, insulin pens, insulin pumps and a variety of "smart" devices and closed-loops devices integrated with a continuous glucose monitor. Diet and exercise are also important treatment methods that help manage your blood glucose levels. Keep your blood glucose within target levels and maximize your "Time in Range" (TIR)!
