Thank you for your query.
There are some questions for you.
The child must be on insulin
i suppose.I need to know the amount ,time,type of insulin delivered to your child.Hba1c
indicates good glycemic control over the last 3months..Her renal threshold should be high thats why she is nor showing ketones or sugar in urine.Kindly enquire if your child is taking extra calories without your knowledge.
Consult your diabetologist
if this problem persistes.Hope this answers your query.If you have any other queries kindly direct them to me.Wishing your child a speedy recovery.Have a nice day.
