Both the white (answered a post on this forum) and the blue (took some meds) arrows show where I got up to got to the toilet and the yellow arrow is where I got up to have a wash and get dressed.
I’ve looked at data for previous nights and I can see the same thing, so the observations are real.
It makes me wonder if the ‘Dawn phenomenon’ is more of an exaggerated version of my nocturnal toilet visits ?
If so, what would happen when you get up to wash and dress, if you did it in stages, lying down after each stage, would you get a series of glucose bumps with the same baseline after, rather than an increase in blood glucose that then plateaus. The bumps do seem to be very responsive.
This is interesting. I think we should distinguish between glucose rising at wake-up as the liver adds more fuel to the system for normal function vs glucose rising to (unhealthy if chronic) high levels due to stress response (liver provides extra fuel to be ready for surviving a perceived extreme situation). I understand the latter to be the “Dawn Phenomenon”. I get the same effect when I get on my bike for a race….very high blood glucose (I found this when I wore a CGM for a short time).
I found the same thing (large glucose spike) when exercising, like you, I only found it out after wearing a CGM. I now exercise more frequently but for smaller periods of time.
It’s more the intensity rather than the duration. If I stay in the aerobic zone then I’m mostly burning fats and the some of the glucose present in the blood so it goes down. If I go over VT1 and start to use some anaerobic power (which can only burn glucose) then the liver makes more of it and the glucose goes up.
Short anaerobic exercise would work too as that will burn some of the glycogen but then at some point the liver starts to produce glucose.
