I understand that low BG is typically much more capable at making itself fatal than high BGs (T1 myself, like half the people in this thread.)

> > Abbott Diabetes Care stated that certain FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors provide incorrect low glucose readings.

My understanding is the problem is probably the same, or likely related to, the pressure low - where basically if you eg lie down on the side of the sensor, it can produce a false low sugar reading.

Presumably, this could push some (already sick) people towards DKA. DKA can go from "slightly bad" to "crazy bad" in a span of hours. (Don't, or do ask me how I know.)

Add in reluctance of people to go to the hospital in the US, and I can totally see how people might've died because of it.

It's a bit of a swiss cheeshole/perfect storm - poor BG management, likely not well enough to afford a hospital, possibly already sick - and unfortunately I'd imagine economically struggling people are likely to have a significant overlap of many of these at the same time. Tragic, but realistic, given the sheer scale of many people use these devices.
