Circulating ghrelin levels in the newborn are positively associated with gestational age

objective  Ghrelin exerts potent GH‐releasing activity and stimulates food intake. Circulating ghrelin levels are increased in anorexia and cachexia, reduced in obesity and restored by weight recovery. Newborns are characterized by GH hypersecretion associated with low IGF‐I levels reflecting peripheral GH resistance.
