Hormone-induced diarrhea in man.

H Pointner, U Flegel

    Acta Hepato-Gastroenterologica
    |June 1, 1975
    PubMed
    Summary

    Infusions of gastrin and glucagon together caused severe diarrhea in healthy subjects. However, secretin and gastrin, or secretin and glucagon alone, did not induce diarrhea.

    Area of Science:

    • Gastroenterology
    • Endocrinology
    • Physiology

    Background:

    • Hormones like gastrin, secretin, and glucagon play crucial roles in regulating gastrointestinal function.
    • Understanding the specific effects of these hormones, individually and in combination, is important for comprehending digestive processes and potential disruptions.

    Purpose of the Study:

    • To investigate the effects of single hormone infusions (secretin, glucagon, gastrin) and their combinations on gastrointestinal motility and symptoms in healthy subjects.
    • To determine if specific hormone combinations can induce gastrointestinal distress, such as diarrhea.

    Main Methods:

    • Healthy subjects received intravenous infusions of either secretin, glucagon, or gastrin.
    • Subsequent infusions involved combinations of these hormones (gastrin and glucagon; secretin and gastrin).
    • Diarrhea and other symptoms were monitored during and after the 3-hour infusions.

    Main Results:

    • Infusions of secretin alone or glucagon alone did not cause diarrhea.
    • A combination of gastrin and glucagon induced severe, watery diarrhea immediately following the infusion.
    • The combination of secretin and gastrin did not result in diarrhea.

    Conclusions:

    • The combination of gastrin and glucagon has a potent diarrheal effect in healthy individuals.
    • Secretin may counteract or not interact synergistically with gastrin to produce diarrhea.
    • This suggests specific hormonal interactions can significantly impact gastrointestinal function and symptom presentation.
