    This review explores gastrointestinal hormones, focusing on defining these peptides, their brain-gut connections, physiological roles, and clinical applications for physicians. It highlights the rapid advancements in understanding these vital signaling molecules.

    Area of Science:

    • Endocrinology
    • Neurogastroenterology
    • Physiology

    Background:

    • Gastrointestinal hormones have seen an exponential increase in discovered peptides and functions over the past decade.
    • Keeping pace with monthly discoveries in peptide research presents challenges even for experts.
    • A 1973 review highlighted the early understanding of gastrointestinal hormones.

    Purpose of the Study:

    • To define gastrointestinal hormones and their classification.
    • To explore the concept of brain-gut peptides and their evolutionary links.
    • To identify gastrointestinal peptides with defined physiological roles.
    • To assess the clinical utility of gastrointestinal hormone measurements.

    Main Methods:

    • Literature review focusing on recent advancements in gastrointestinal peptide research.
