Changes in gastric emptying rates with age.

M Horowitz, G J Maddern, B E Chatterton

    Clinical Science (London, England : 1979)
    |August 1, 1984

    Summary

    Gastric emptying of solids and liquids slows slightly with age. However, these changes are minor and generally remain within normal ranges, suggesting limited clinical significance for healthy older adults.

    Area of Science:

    • Gastroenterology
    • Gerontology
    • Physiology

    Background:

    • Gastric emptying is crucial for nutrient absorption and digestive health.
    • Age-related physiological changes can impact gastrointestinal function.
    • Understanding gastric emptying in aging populations is important for maintaining nutritional status.

    Purpose of the Study:

    • To investigate the effect of age on gastric emptying of both solid and liquid meals.
    • To assess whether age-related changes in gastric emptying are clinically significant in healthy individuals.

    Main Methods:

    • Utilized a dual isotope technique for simultaneous measurement of solid and liquid gastric emptying.
    • Studied 35 healthy, mobile volunteers aged 21-84 years, free from any medications.
    • Analyzed gastric emptying rates across different age groups.

    Main Results:

    • A statistically significant slowing of both solid and liquid gastric emptying was observed in older subjects compared to younger ones.
    • Despite the slowing, the observed changes were small.
    • Gastric emptying rates in older subjects typically remained within the normal range established for younger individuals.

    Conclusions:

    • While aging is associated with a slight decrease in gastric emptying speed for solids and liquids, the effect is minimal.
    • These age-related alterations in gastric emptying are unlikely to be of significant clinical concern in healthy, active older adults.
    • Gastric emptying function remains largely preserved in healthy aging individuals.
