5. Alarm Systems

Alarm systems warn people with T1D when hypoglycemia occurs or can be predicted to occur in the near future if the current glucose concentration trends continue. Various alarm system development strategies are outlined in this chapter. Severe hypoglycemia has significant effects ranging from dizziness to diabetic coma and death while long periods of hyperglycemia cause damage to the vascular system. Fear of hypoglycemia is a major concern for many people with T1D. High doses of exogenous insulin relative to food, activity and low blood glucose levels can precipitate hypoglycemia. Hypoglycemia and hyperglycemia early alarm systems would be very beneficial for people with T1D to warn them or their caregivers about the potential hypoglycemia and hyperglycemia episode before it happens and empowers them to take measures to prevent these events.
