The function of the stomach and the gut hormonal responses to food ingestion constitute highly integrated homeostatic responses that maintain euglycemia and normal digestion. This intrinsic feedback involves vagal and hormonal mechanisms. Important signals such as GLP-1 and PYY that arise peripherally induce satiation and also delay gastric emptying or increase insulin secretion. Novel therapies are being developed to mimic or enhance these feedback mechanisms and to control appetite as a means to treat obesity.
胃的功能以及肠道对食物摄入的激素反应构成了高度整合的稳态反应,以维持血糖正常和正常消化。这种内在反馈涉及迷走神经和激素机制。诸如胰高血糖素样肽-1(GLP-1)和肽YY(PYY)等重要信号在外周产生,可诱导饱腹感,还能延迟胃排空或增加胰岛素分泌。目前正在开发新的疗法来模拟或增强这些反馈机制,并控制食欲以治疗肥胖症。
