I researched a little more yesterday and I'm now thinking it may be hypoglycemia just by some of the numbers that have been coming up in his blood. But I'm not sure what normal numbers are
It should have been:
I also had some "white areas" below my eyes. (my skin were extra dry there)
At least I'm pretty sure I didn't have any of the symptions you're mentioning..
My uncle (my father's brother) have had diabetes type 1 since he was 18, so our entire family have know about our increased risks of getting diabetes. Some months before I turned 8, my mother and father became aware of that I waked on the middle of almost every night, and went to the bathroom to pee. I also had some "white areas". They brought me to the doctor, and he found out I had diabetes.
You could also check if his breath smells like acetone - if it does his blood sugar is above 18. People without diabetes should have a blood sugar between 4 and 8.
