thank you for your query.
the problem you are stating is a very common one.hence you dont need to worry.
as the endocrinology and genetic investigations have come up without any problem.i think it is a natural state for your daughter.
a reason fro this can be that your daughter is a fast oxidizer.such tend to get hot, especially when they eat carbohydrates. The diet recommended for them is a high protein, high fat diet.
it is not a reason for concern,but you can still try the diet plan
if you want to.
you can contact me for any further queries.
