Individual sensitivity to lactose in lactose malabsorption.

E Gudmand-Hoyer, K Simony

    The American Journal of Digestive Diseases
    |March 1, 1977
    PubMed
    Summary

    Lactose malabsorption affects individuals differently. Some patients experience relief with lactose-free diets, while others develop irritable bowel syndrome symptoms, indicating a complex digestive response.

    Area of Science:

    • Gastroenterology
    • Human Physiology

    Background:

    • Lactose malabsorption is common, but individual responses to lactose vary.
    • Understanding patient sensitivity is crucial for managing digestive disorders.

    Purpose of the Study:

    • To investigate the clinical significance of lactose malabsorption.
    • To assess individual patient sensitivity to lactose intake.

    Main Methods:

    • Studied 20 patients with confirmed lactose malabsorption.
    • Administered lactose in increasing amounts to assess symptom provocation.

    Main Results:

    • 13 patients were symptom-free on a lactose-free diet.
    • 7 patients improved but experienced increased discomfort with lactose provocation.
    • Some patients showed a tendency towards constipation, suggesting co-existing irritable bowel syndrome.

    Conclusions:

    • Lactose malabsorption alone does not explain all symptoms in some patients.
    • Irritable bowel syndrome with a tendency to constipation may co-exist with lactose malabsorption.
