Hi
New to this
I have recently started using a libre 2 sensor.
This has been my first holiday using it.
Over the last few days readings have been very low in the threes,however I feel very full.
Haven't been able to use a glucose terminal.
My question is done sunlight affect the sensor ?
Its been about 25 degrees c
Any info appreciated
Will it return to normal ? Does anyone know ?
Thank you

Hi, welcome to the forum.

It’s hard to say regarding the sensor reading without checking against a BG meter?

In my experience.
As a T1 in hotter climates I tend to be a little more insulin sensitive. (Need to lower my basal dose.)
I’ve also worked in “sun traps” just around/over the 30c mark & only had one Libre error where it decided to stop until it could chop sense into a reading? (Ironically I was working in the shade of a 6 foot panel fence..)

Others may have ideas.
 
I had a sensor die on me when I’d been working in the garden with the sun on it for 2 hours on a hot summer day. It showed a very low reading first, then after about 10 mins it stopped working altogether.

Without double checking with a fingerprick test there is no way if your sensor is off.
Sometimes sensors don't work well, they can also work but read lower than blood.
I've used Libre sensors for 9 years and haven't noticed a difference in how they read depending on heat. (Although they do give a 'sensor too cold' error when the sensor gets below 10 °C)

I see you're on gliclazide, which can cause hypos.
Can you do a fingerprick test?
 
I've sat in direct sunlight and just got a warning on my phone that the sensor was too hot but I don't think it changed the accuracy of the reading much.
