We agree on the metabolic reasoning! I freely admit that 98% of my experience with diabetes has been in the field dealing with hypo or hyperglycemic patients. Obviously, we are talking about diabetics that aren't the most compliant with their disease. However, even "good" diabetics have bad runs with questionable supplies, or any host of issues (sickness, environment, diet change, etc.)

I happen to live where a very, very large cluster of diabetics are studied. We do a lot of diabetic emergencies... I can count on my hands how many times we've used glucagon. Like I said, we can treat and release with D50. Not so with Glucagon.

If "they" figure out the delicate balance between all the systems in order to use glucagon the same way it is regulated in a non-diabetic; it stands to reason that "they" should have a way to repair/replace the islets of Langerhans as the first priority, don't you think?
