Ghrelin Ghrelin Ghrelin (pronounced ), the "hunger hormone", also known as lenomorelin (INN), is a peptide hormone produced by ghrelinergic cells in the gastrointestinal tract that functions as a neuropeptide in the central nervous system. Besides regulating appetite, ghrelin also plays a significant role in regulating the distribution and rate of use of energy. When the stomach is empty, ghrelin is secreted. When the stomach is stretched, secretion stops. It acts on hypothalamic brain cells both to increase hunger, and to increase gastric acid secretion and gastrointestinal motility to prepare the body for food intake.

Growth hormone therapy shortness with normal test results as a disease rather than the extreme end of the normal height range Recombinant growth hormone available in the U.S. (and their manufacturers) included "Nutropin" (Genentech), "Humatrope" (Eli Lilly and Company), "Genotropin" (Pfizer), "Norditropin" (Novo Nordisk), "Tev-Tropin" (Teva) and "Saizen" (Merck Serono). The products are nearly identical in composition, efficacy, and cost, varying primarily in the formulations and delivery devices. Growth hormone (GH l) is also called somatotropin (British: somatotrophin). The human form of growth hormone is known as human growth hormone, or hGH (ovine growth hormone, or sheep growth hormone, is abbreviated oGH). GH
