Impaired gastric function in experimental malnutrition

H Thomason, V Burke, M Gracey

    The American Journal of Clinical Nutrition
    |July 1, 1981
    PubMed
    Summary

    Selective protein restriction in rats impaired gastric acid secretion, independent of body weight. This finding suggests a role in malnutrition, potentially reducing the stomach's ability to control bacteria in the upper gut.

    Area of Science:

    • Gastroenterology
    • Nutritional Science
    • Physiology

    Background:

    • Dietary protein is crucial for physiological functions.
    • Gastric acid secretion plays a role in digestion and microbial defense.
    • Malnutrition can have diverse pathophysiological consequences.

    Purpose of the Study:

    • To investigate the effect of selective protein deprivation on gastric acid secretion.
    • To determine if impaired secretion is linked to reduced body weight.
    • To explore the implications for bacterial control in the upper gastrointestinal tract.

    Main Methods:

    • Rats were subjected to selective dietary protein deprivation.
    • Pentagastrin-stimulated gastric acid secretion was measured.
    • Body weights of experimental and control groups were compared.

    Main Results:

    • Protein-deprived rats exhibited impaired gastric acid secretion.
    • The impairment was observed independently of reduced body weight.
    • This suggests a direct effect of protein deficiency on gastric function.

    Conclusions:

    • Selective protein deprivation directly impairs gastric acid secretion.
    • This dysfunction may contribute to altered microbial populations in malnutrition.
    • Reduced gastric acid control could be a significant factor in clinical malnutrition.
