growth hormone decrease
pituitary insuff, GH deficient, hyperglycemia
growth hormone stim test
give insulin to cause hypoglyc, if GH >10x => positive for excessive response
growth hormone suppress test
give glucose to cause hyperglyc, if GH does not change => positive for insufficient regulation
GH effects
increase skeletal growth, increase free FA, increase gluconeogen, increase blood to kidneys
