Guys!! Morning Blood Sugar? Seriously All Over The Place!

Guys!.

I'm a type one Diabetic and have the Libre Freestyle sensor. Great Job!!

Unfortunately recently I've been having issues with my morning blood sugar!

I own my own business and nights can be all over the place but even with going to bed with a sugar reading of 5/6 and taking my correct long lasting insulin I'm having issues.

The sensor gives me the ability to see a graph of what happened my sugars during the night and seems that I'm staying correct to about 5/6 then rocketing high for the next hour until I take my morning insulin.

Any ideas or anyone had this? my daytime control is pretty good and the highs are worrying me now as they have been on going for a few weeks.

cheers,
Matty
 
This sounds like Dawn Phenomenon (DP).
As our bodies wake, our livers release a ton of glucose to give us the energy to get up.
This happens to most people; those with healthy pancreas just release insulin to give convert the glucose to energy.

DP is a common driver to a pump as we can control our basal to handle different daily needs.
I know some people wake early morning, give themselves a bolus boost and then go back to sleep until they need to get up.
Others have found eating their evening meal earlier (or eating lower carbs) reduces DP.
 
Just to give you some of my personal experience with the same freestyle libre sensor.

I woke up with a blood sugar of 9mmol/L as per test strip while my freestyle sensor read 17.9 mmol/L.

Over the next 2 hours my blood sugar remained between 10.1 mmol/L and 11.2 mmol/L as per test strip while my freestlye libre read between 15.9 mmol/L and 17.9 mmol/L.

I get constant extreme varying results at all times between the libre and test strip and they are never the same. Even when my blood sugar has remained at 4.6 mmol/L for 5 hours testing every 30 minutes the libre has show values ranging from 5.6 mmol to 8.8 mmol/L.

Just something for you to take into consideration.

Also, you want to look at what your last meal time is, how many calories, carbs, fat, and protein is it. One of those along with what the others said (DP) are usually the problem.

I experience similar differences between finger prick and Libre (and other DexCom).
I believe some people are more Libre-compatible than others.
I do not know why this is. It may be because my BG changes rapidly (especially when exercising); it may be because I move a lot which means the sensor is not stable (I have tried moving the sensor but not found anywhere I keep still for long enough); it may be my interstitial fluid is flaky; ...

With my experience, I do not think the Libre is a waste but the value is only in watching the trends.
I am able to use Libre to check my insulin dose and timing for different foods, exercise, etc. at different times of the day.
I am not able to use Libre to calculate my insulin dose or do corrections.

I think you hit the nail on the head.

I too am always moving and do ample amount of exercise throughout the day so the common variable seems to be with the amount of movement for the freestyle Libre.

I think so too that it's still useful.. For example let's say at 1pm you see 10 mmol/L and at 2pm you see 7 mmol/L with a trending down arrow, for me it's safe to say I'm around the 5.0 range so I should check my IOB which now gives me the capability to make an accurate decision without checking via prick IF I WANTED. I always prick though, I need to be accurate lol.
 
I'm not sure it's the movement which is causing the differences - it's pretty accurate for me, regardless of the amount of activity I'm doing.
 
Libre has been accurate for me when I've been on Lantus, Toujeo and Levemir.
