Metabolic responses to exogenous ghrelin in obesity and early afterRoux‐en‐Ygastric bypass in humans

Aims Ghrelin is a gastric‐derived hormone that stimulates growth hormone ( GH ) secretion and has a multi‐faceted role in the regulation of energy homeostasis, including glucose metabolism. Circulating ghrelin concentrations are modulated in response to nutritional status, but responses to ghrelin in altered metabolic states are poorly understood. We investigated the metabolic effects of ghrelin in obesity and early after R oux‐en‐ Y gastric...
