    Iron deficiency in piglets impairs gastric acid and chloride secretion, leading to atrophic gastritis. However, gastric motility remains unaffected in iron-deprived animals.

    Area of Science:

    • Gastroenterology
    • Nutritional Science
    • Pediatric Research

    Background:

    • Iron deficiency anemia is a common condition in infants and young children.
    • The role of iron in gastric function and structure is not fully understood.
    • Piglets are a suitable model for studying human infant physiology.

    Purpose of the Study:

    • To investigate the effects of iron deficiency on gastric motility, secretion, and structure in weaned piglets.
    • To determine if iron deficiency impacts gastric acid production and histological integrity.

    Main Methods:

    • Piglets were weaned and raised in iron-free conditions, with some receiving parenteral iron supplementation.
    • Gastric motility was assessed using fluoroscopy after barium sulfate administration.

  • Gastric secretion was measured in cannulated piglets stimulated with betazole hydrochloride.
  • Gastric tissue was examined histologically.

    • Main Results:

    • Iron-deprived piglets rapidly developed iron deficiency anemia.
    • No significant differences in gastric motility were observed between iron-treated and iron-deprived groups.
    • Iron-deprived piglets exhibited significantly impaired gastric acid and chloride secretion.
    • Histological examination revealed evidence of atrophic gastritis in iron-deprived animals.

    Conclusions:

    • Iron deficiency significantly impairs gastric acid and chloride secretion in piglets.
    • Iron deficiency leads to histological changes indicative of atrophic gastritis.
    • Gastric motility is not affected by iron deficiency in this model.
    • Early iron supplementation is crucial for maintaining normal gastric function and structure in young mammals.
