I suggest that you speak to your wife before correcting my unimpeachable explanation of why someone might die from being told, incorrectly by their CGM, that their blood glucose is low.
I say this as someone doesn't need to rely on a spouse but have actually received my own medical education. And I've had my own HHS patients—it's not even clear if your wife (!!) works in this area.
As the sibling commentator shares, we don't really expect these patients to show up after a day of bad data, but we also have no idea how many days of bad data occurred.
As someone that experienced DKA when I was young I'm still not sure how that happens unless there were a lot of other confounding factors. Having hypoglycemia that high for a while will make everything start smelling like varnish. Also you start physically hurting especially your kidneys which is not something you can ignore.
If there were other confounding factors then I'm wondering what their endo told them, unless this is one of those countries you could buy it without a prescription? Any endo with any training would have a fragile diabetic using more than one monitoring method and have them doing regular blood tests.
