acquired hypothyrodism causes
Proportionate short stature in children
effect of androgen on physical activity
Excess androgens cause tall stature as a child but proportionate short stature later as an adult.

failure to thrive and asthenia
Excess steroids whether endogenous or exogenous causes
short stature with characteristic obesity (Cushing syndrome).
