Hi there,
I am someone who was diagnosed 51 years ago at age 13 , so whilst not a mom or female i can still understand your anguish !
The usual advice with high bsls is to check for ketones - these are the by products of our body burning fat as an alternative to burning sugar as an energy source when sugar cannot get into the body cells. High Bsls and ketones are a bad combination as ketones in increasing numbers can make the blood more acid and also make insulin less effective.
Ketones can be measured either with special test strips in certain gluco-meters or with urine testing strips,
I cannot quite fathom the attitude of allowing high bsls without testing for ketones. But it may be that the dsn is worried about a corrective dose of insulin at midnight might cause your 7 y/o to have a hypo ( low blood sugar) later.
Certainly working out why your 7 y/o is that high in Bsl at midnight is important. ? Not enough insulin working ? Too much dinner and supper ?
Also i have found that if I exercise with my bsl > 14, my liver makes more glucose and my bsl goes up and i feel terrible, so i do not exercise unless my bsl is < 12.
Also i find that even with bsl < 12 at onset vigorous exercise causes my bsl to rise a bit die to the adtenaline causeing my bsl to rise BUT it falls 6 + hours later. So i ignore the high reading directly after exercise and watch out for a possible low bsl ) < 4) at 6 + hours later.
No doubt the dsn will discuss what adjustments/ ways that your 7 y/o can make to cope with exetcise and reduce the risk of low bsls later.
Hopefully the dsn will also advise on how to prevent the high bsl at 12 mn.!
Best Wishes to you and your 7 y/o !!
