There is universal agreement that iatrogenic hypoglycemia is the single most prominent barrier to the safe, effective management of blood sugar in people with type 1 diabetes (T1D). The typical patient with T1D is required to "count" the number of carbohydrates they consume, estimate their own insulin doses and deliver this insulin subcutaneously to manage their own glycemic level. With these multiple degrees of freedom, it is not surprising that people with T1D frequently over-insulinize, thereby putting themselves at increased risk of developing hypoglycemia and its associated comorbidities.
