Late Morning BG

[LionChild]

I'm grateful for the advice given several weeks ago, regarding my high morning Libre readings, and as suggested, I adjusted my Levemir by splitting it into 2 units at night, 4 in the morning. At first this worked very well, but this morning I found my BG went up to 9.8 without having eaten or drunk anything at all since last night when I had dinner at around 7 pm.

When first getting up this morning, my BG was okay, I think at 7.2. This was at 9 am. At 10.38 am it was 7.4. Then for some reason it went up to 9.8 at 11.38! only eventually coming down to 8.7 at 12.01, and then again up to 9.4 at 12.16!

I know that what can work is actually to have breakfast (which I normally skip and take 1 unit of Novorapid to deal with any rises), as having breakfast can stop this rise, but it has not been my custom to eat breakfast, I usually fast, and it doesn't always seem to work that way---that eating something can prevent the liver chucking the glucose out...

2 factors I have considered about this morning's massive rise. One was that I had a shower this morning before the rise... Can a warm shower make your blood glucose go up as much as this? And the second factor is that I injected in my legs, both Novorapid and Levemir this morning -----as my poor tummy seems to be punctured all over the place, and I thought it would be good to rotate a bit more.....

My last A1C was an excellent 41, (several weeks ago - in fact before splitting Levemir dose), but my experience today and yesterday in fact was really quite hair-raising. I tried to bring my blood glucose down yesterday by going on my exercise bike, and actually did 35 minutes, (in 5 minute periods), but it was very hard work and did not really seem to make a great deal of difference in bringing down BG. (and even at 10.15 pm my BG then was 9.0!--having eaten egg salad at 7pm).

Does anyone have any theories or suggestions as to what might be going on here?

Thank you!

How are you testing your blood sugars?
I find heat from my shower (I like hot showers) on my Libre (or other CGM) sensor can cause it to read high but it soon recovers without insulin making me think the problem is a false reading on the sensor rather than my body's reaction.

If you normally skip breakfast I wouldn't be adding it back just to bring down your little pre lunch spike.
The proximal reason for this mini spike is just that your liver has decided to produce a little glucose from your fat stores just as is normal when you've fasted for over 12 hours. As type 1 you have an imbalance of glucagon versus insulin and the latter would normally kick in to supress this slight surge. I often skip breakfast but do eat as poon of nut butter just to reassure my body that there s fuel on board but I've also taken a low carb approach for a few years now so it is used to fat so not sure how that would work for you.
And when you take your lunchtime insulin this hopefully brings things into normal range again.
Things like stress or resistance training may provoke the production of glucose too so try and do something gentler that doesn't generate a stress response e.g. a not very hard cycle or walk or yoga perhaps.
Warm showers should help insulin work better and as for jab sites, yes keep an eye out for bruising/lumps/bumps but if there's none of that and you are holding the pen for a little while so allow the insulin to stay under the skin then I don't think that poor jab technique or location is to blame.
Remember that 'normals/ may also get occasional surges before lunch but they don't usually measure them or worry about them in the way that we type 1s are trained to.

The testing is via libre though clearly I need to do some finger pricks for this--- as it's so odd. It was quite a long time after my shower that the BG was so high which is why I would question whether it was a false reading.
