Welcome to the Forum!
I am no doctor, just offering some suggestions. It appears that your daughter may be experiencing some form of
hyperglycemia. You didn't say if her doctor had recommended a diet, but I would try a diabetes diet - it's how everyone should eat - lean proteins, low fat, unprocessed carbs from fruits and vegetables and plenty of exercise. Learn to
count carbs and be sure to keep all the doctor's appointments. The doctor will make the final determination, but you can help in the mean time. Good luck with your child's diagnosis, I wish you both the best.
