HGH is a hormone normally made in tiny amounts by the pituitary gland in all of us.
Others who, because of a tumor in the pituitary gland, may overproduce HGH develop a different problem: gigantism.
At the other end, a tumor of the pituitary can over-produce growth hormone and cause acromegaly.
1610s, from Latin pituitarius "mucous," from pituita "clammy moisture, phlegm, mucus, slime," possibly from PIE root *peie- "to be fat, swell" (see pine (n.)). Taken as the name for the gland because it was believed that it channeled mucus to the nose. As a noun by 1899.
