Summary

Thai infants exhibit a biphasic gastric emptying pattern for milk. Stomach contents increase at 40 minutes before decreasing significantly by 100 minutes, establishing a reference for infant health studies.

Area of Science:

  • Pediatrics
  • Gastroenterology
  • Infant Nutrition

Background:

  • Understanding infant gastric emptying is crucial for assessing nutritional status and identifying potential gastrointestinal issues.
  • Previous research on gastric emptying in infants, particularly in diverse populations, provides a foundation for this study.

Purpose of the Study:

  • To characterize the gastric emptying pattern of milk in healthy Thai infants.
  • To establish a normative reference for gastric emptying in this specific infant population.

Main Methods:

  • Milk-based meal administered to Thai infants.
  • Gastric content volume measured at specific time points post-feeding (20, 40, and 100 minutes).
  • Analysis of the temporal pattern of stomach content reduction.

Main Results:

  • Gastric emptying demonstrated a biphasic pattern, with increased stomach contents at 40 minutes compared to 20 minutes.
  • By 100 minutes, only 16% of the initial milk volume remained in the stomach.
  • This biphasic pattern suggests a unique physiological response in Thai infants.

Conclusions:

  • The study successfully characterized a distinct biphasic gastric emptying pattern for milk in Thai infants.
  • These findings provide a valuable reference standard for future research on infant gastrointestinal physiology and disease.
  • This data can aid in the diagnosis and management of feeding disorders in infants.
