pituitary dwarfism whats up
low grwoth hormone production or tissues nt responding to growth hormone
gigantism whats going on and when seen
increased growth hormone production (usually 2/2 pituitary adenooma) before epiphyseal plates close
20% cases 2/2 McCune-Albright syndrome
increased growth hormone possibel scenarios
if before epiphyseal plates close –> gigantism
if after –> acromegaly

cretinism
hypothyroid –> gags
