Ghrelin is a potent secretagogue of pituitary growth hormone (but not adrenocoicotropic hormone, follicle-stimulating hormone, luteinizing hormone, prolactin, or thyroid-stimulating hormone). Ghrelin appears to be an orexigenic regulator of appetite (i.e., when ghrelin is elevated, appetite is stimulated, and when it is suppressed, appetite is suppressed). Ref: Dempsey D.T. (2010).
