Breath hydrogen in hyposucrasia.

G Metz, D J Jenkins, A Newman

    Lancet (London, England)
    |January 17, 1976
    PubMed
    Summary

    Diagnosing hyposucrasia, a cause of gastrointestinal issues, is now simpler. Breath hydrogen testing after sucrose intake accurately identifies this condition, offering a reliable, non-invasive diagnostic tool.

    Area of Science:

    • Gastroenterology
    • Digestive Health
    • Diagnostic Medicine

    Background:

    • Hyposucrasia, a condition affecting sucrose digestion, can be an overlooked cause of chronic gastrointestinal problems.
    • Current diagnostic methods for hyposucrasia are limited, hindering epidemiological studies.
    • Breath hydrogen testing is an established non-invasive method for diagnosing hypolactasia.

    Purpose of the Study:

    • To evaluate the efficacy of breath hydrogen testing for diagnosing hyposucrasia.
    • To establish a simple and reliable diagnostic method for hyposucrasia.

    Main Methods:

    • Breath hydrogen (H2) levels were measured in eleven patients with gastrointestinal symptoms after sucrose ingestion.
    • Sucrase activity was assessed via jejunal biopsy in some patients.
    • Different doses of sucrose (50g, 100g) and glucose (25g) were administered.

    Main Results:

    • Patients with normal jejunal sucrase activity showed no significant breath H2 rise after 50g sucrose.
    • Patients with borderline hyposucrasia did not produce H2 even with 100g sucrose.
    • Two patients with low jejunal sucrase activity exhibited elevated breath H2 levels after 25g glucose.

    Conclusions:

    • Breath hydrogen measurement after sucrose ingestion is a simple, accurate, and non-invasive test for diagnosing hyposucrasia.
    • This method can help identify gastrointestinal symptoms linked to impaired sucrose digestion.
    • Breath H2 testing offers a viable alternative to more invasive diagnostic procedures.
