Why ur brother is taking his height to his nerves? height is dependent on heredity, physical, nutritional and hormonal factors. The duration for rapid height growth in boys is 13-21 years and maximum at the age of 15-18 years. why u people didn't noticed this thing at that age?
now, dont go to any hakeem or homeo doctor, they will only make money by giving fake medicines.
struggle to increase ur social and educational height, it will benefit u, more than the physical appearance.
