Preventing these situations entirely by predicting these events and reducing the administered basal insulin would be ideal, but humans don't exist in a vacuum.

Preventing these situations entirely by predicting these events and reducing the administered basal insulin would be ideal, but humans don't exist in a vacuum. I don't think a system autonomously feeding sugar would be the optimal solution however; patients who utilize CGM's today are still instructed to monitor blood glucose through traditional means for calibration and confidence in system accuracy, so I don't think it would be an additional burden for them to continue to carry a source of sugar for emergency hypoglycemic events. I think predicting and preventing lows through lowered basal rates, in combination with on hand sources of glucose for emergency situations, would be best. Even a reduction in the amount of hypo- (and, hyper-) glycemic events would be a big win for patients and educators. I think the quality of care would vastly increase with such systems in place. Additionally - the human body has systems in place to bring blood sugars back into a safe range when it feels it is in an emergency situation. I do not claim to be an expert on this matter, but it is my understanding that the liver is able to release glycogen into the system to spike blood glucose levels back up if they have fallen low [1]. This is why some diabetic patients may experience high blood sugars in the mornings if they have experienced a hypoglycemic event overnight and slept through it. I don't believe this would be a good solution to depend on, however.
