Hi,
@DeeGem , I'd second
@endocrinegremlin 's suggestion of asking for a libre or cgm trial.
Cgm is a continuous glucose monitor. A small sensor is put on the arm, measures bg every 5 mins, sends it to a phone app, so she'll get a continuous 24 hr graph trace to see exactly what bg has been and is doing. Can also input bolus and carb amounts to see the effects of those. The phone can be set up to ring if going too high or low, so the user gets a heads up on whether they need to do something. Libre can be set up with a little gizmo to do that too.
There seems to be lots of unexplained hypos and hypers going on with your daughter's bg.
It can be very difficult to identify the reasons for those if she's just using strips - they just give a brief glimpse of a point in time. It's like fighting in the dark.
With cgm, though, as you can see the full 24 hr picture, it's waaay easier to see what's going on, and take steps to steer it to mitigate/ mimimise highs and lows before they happen. And look back at the past history to see if there are any recurring patterns, which lets you think ahead about ways to stitch them.
Before I got cgm, there was a lot of things happening with my T1 that I just couldn't figure out. It frustrated me.
After cgm, it just became much, much easier to look at the graphs, and say, right, ok, I can see now what's going on here, and then start steering it.
You and your daughter are sounding confused and uncertain at the moment. T1 is an unpredictable, difficult thing to manage.
Pretty much everyone who has used either libre or cgm says it makes it much, much easier, because you can see what it is doing, and then figure out ways to fix the bad bits.
I'd strongly encourage you and her to ask her team about scripting libre or cgm for her - there's a fair chance it will make a lot of the unexplainable things happening at the moment a lot more understandable, and, more importantly, also see ways of changing doses, ratios, pre-bolusing, basal, dextrotab nudges, etc. etc. to fix them. It makes the game much fairer.
If you've got a kindle, get a copy of Sugar Surfing by Stephen Ponder to get a clearer idea of what cgm brings to the game.
Good luck!
