Motilin in chronic idiopathic constipation.

K Sjölund, R Ekman, F Akre

    Scandinavian Journal of Gastroenterology
    |October 1, 1986
    PubMed
    Summary

    Patients with severe constipation show reduced plasma motilin levels and impaired motilin release after a meal. This suggests a defective motilin release may contribute to the development of idiopathic constipation.

    Area of Science:

    • Gastroenterology
    • Endocrinology
    • Physiology

    Background:

    • Idiopathic constipation is a common condition with unclear pathogenesis.
    • Motilin is a gastrointestinal hormone that regulates gut motility.
    • Reduced motilin levels have been anecdotally linked to constipation.

    Purpose of the Study:

    • To investigate plasma motilin levels in patients with severe idiopathic constipation.
    • To compare motilin release after a fat-rich meal in constipated patients versus healthy controls.
    • To explore the potential role of motilin deficiency in the pathophysiology of constipation.

    Main Methods:

    • Studied seven patients with severe long-standing idiopathic constipation.
    • Measured plasma motilin levels before and after a standardized fat-rich test meal.
    • Compared results with a control group of 10 healthy individuals with normal bowel function.

    Main Results:

    • Constipated patients exhibited lower basal plasma motilin levels compared to controls.
    • Patients with constipation showed a blunted motilin release in response to the test meal.
    • A significant difference in motilin profiles was observed between the two groups.

    Conclusions:

    • Defective motilin release may be implicated in the pathogenesis of severe idiopathic constipation.
    • Motilin's role in stimulating intestinal motility, particularly descending contractions, is crucial.
    • Further research is warranted to elucidate the therapeutic potential of targeting motilin pathways.
