Hello. Advice needed..

[crunnycrun]

Hi. I'm type 1 and have been for 20 years after being diagnosed at the age of 23.
I recently got the sensor and have Been using for maybe three months now. I can't seem to figure out why when I check in the morning, my glucose levels have been yo-yoing all night. Not going into hypo but going down then up etc.
Anyone know why this could be?
Thanks.
(I'm aware that my levels are high in the pic)

Welcome to the forum @crunnycrun I am glad that you have found us.

The only thing that I can think of is whether there are dips due to compressions, you rolling on to the sensor of it is in your arm. If so these can be reduced by putting the sensor on the ‘more flabby’ bits but I suspect that you are not old enough to have these very special wings as yet.

I am not using the Libre so I will leave others to come up with other ideas.

As mentioned by Sue, they are almost certainly compression lows. Gradually you learn to either place it further round to the back of your arm or not to lie on the sensor arm or a combination of both.
CGMs like Libre have a number of limitations and it is really important to be aware of them, so that you understand how to interpret their data, when to trust them and when to double check with a finger prick. I will link a thread below which outlines these limitations....

Thanks. The sensor is more to the back of my arm but I do roll around a bit at night. I'm getting there with the "flabby bits" by the way!

Oh and welcome to the forum.

Thank you, I will read into it.

Those short sharp dips with a bounce-back often seem to be compression lows for me. Several times I’ve been woken by a Dex alarm, and found myself leaning on my sensor arm, with slight pins and needles in it.

Those little gaps in the trace seem to happen with Libre when the change of glucose values is more dramatic than it thinks can be possible, and it has to have a little think for 10 minutes!

Thanks for your reply. I'll try and not lie on it tonight.

It’s not always possible, but I find it helpful to know that it is a thing that can happen, as it can make some weird overnight traces / apparent ‘hypos’ more understandable.
