This review covers the gastric hormone ghrelin and its receptor, highlighting ghrelin's role in food intake, body weight regulation, and gastric emptying. Ghrelin levels are significantly altered in conditions like obesity and anorexia.

Area of Science:

  • Endocrinology
  • Gastroenterology
  • Metabolic Research

Background:

  • Ghrelin is a gastric hormone that plays a crucial role in regulating appetite and energy balance.
  • Its receptor mediates various physiological effects, including stimulation of food intake and body weight gain.
  • Ghrelin influences adipogenesis and diabetogenesis, linking it to metabolic disorders.

Purpose of the Study:

  • To review and summarize current data on the gastric hormone ghrelin and its receptor.
  • To explore the physiological roles of ghrelin in food intake, body weight regulation, and gastric function.
  • To discuss the therapeutic potential of targeting the ghrelin system.

Main Methods:

  • Literature review of available scientific data.
  • Analysis of studies investigating ghrelin's effects on appetite and metabolism.

Related Experiment Videos

  • Examination of ghrelin levels in various physiological and pathological states.

    • Main Results:

    • Ghrelin stimulates both short-term food intake and long-term body weight regulation.
    • Ghrelin exhibits adipogenic and diabetogenic effects, impacting metabolic health.
    • Ghrelin influences gastric emptying, suggesting potential therapeutic applications.
    • Ghrelin levels are significantly altered in anorexia, insulin resistance, obesity, and post-bariatric surgery.

    Conclusions:

    • Ghrelin is a key hormone in the complex regulation of body weight.
    • The ghrelin system holds therapeutic potential for conditions related to appetite and metabolism.
    • Further research into ghrelin's mechanisms could lead to novel treatment strategies.
