Ghrelin and the enteroinsular axis in healthy men.

Objective: Ghrelin, a potent stimulator of GH secretion, also acts as an orexigenic hormone. Plasma ghrelin levels rise before meals with postprandial reduction, suggesting that circulating levels of enteroinsular hormones might influence ghrelin secretion.

Aim: The aim of this study was to evaluate the effects of ghrelin on enteroinsular hormones in healthy men.
