DD is 13 and in the last 4 months has gained quite a bit of weight (she is 70kg) but in proportion, this weight gain has coincided with her being tied all the time and her joints are constently clicking.
The weight gain is due to the tiredness and as so lack of exercise.
She has a gp appointment in a weeks time but i am concerned as she also hasn't started her periods.
She eats very healthy and never has sweets, chocolate or crisps and her portion sizes are average if not on the small size.
What could this be???
