How can I show my wife that Libre sensors sometimes report false low‑glucose readings?
I’m a type 2 diabetic, and because of my Libre 3+ my wife barely lets me live in peace. The sensor sometimes triggers low‑glucose alarms, and my wife panics immediately. I’m fully aware of how dangerous a real hypoglycemia can be, but the problem is that these alarms often aren’t real.
It happens especially at night. I’ve read that the sensor can give false readings if you lie on the arm where it’s placed. That matches my experience: I feel completely normal, but the phone beeps, my wife gets alarmed right away, and sends me to the kitchen to eat something immediately. After that I’m wide awake, ripped out of my sleep, and the next day I’m exhausted.
When I go jogging with the dog and carry my phone in an armband right next to the sensor, I sometimes get alarms too. I don’t know whether it’s the movement or the phone being so close to the sensor. In the sauna the readings also go completely crazy sometimes, probably because of the temperature.
Of course I can always do a finger‑prick blood test, and that’s exactly what I’m doing now. But what I really want is to run a few simple experiments to demonstrate that the sensor’s readings can be “manipulated” or distorted under certain conditions.
So far I haven’t managed to deliberately reproduce the false readings, for example by pressing the sensor lightly for a few minutes. I’d like to do a few harmless experiments in front of my wife so she can see that you can trigger a false low‑glucose reading even when there’s no real hypoglycemia.
Does anyone have an idea how to demonstrate these false readings?
Thank you in advance!
