Summary

Aging impacts stomach, gut, and pancreatic function, causing cell changes and secretion decline. However, healthy older adults typically manage these changes well, except during illness or malnutrition.

Area of Science:

  • Gastroenterology
  • Gerontology
  • Physiology

Context:

  • Age-related physiological changes in the gastrointestinal system.
  • Impact of aging on digestive functions.

Purpose:

  • To review current data on the effects of aging on stomach, gut, and pancreatic exocrine function.
  • To discuss the physiological consequences of aging in the digestive system.

Summary:

  • Aging leads to hyperexcitability of gastroduodenal parietal cells.
  • Enterocyte villous surface alterations decrease trophicity with age.
  • Pancreatic exocrine secretion declines in elderly individuals.
  • Despite physiological changes, healthy aging typically does not cause major digestive issues.

Impact:

  • Highlights the resilience of the aging digestive system in healthy individuals.
  • Identifies specific vulnerabilities in elderly subjects facing physiological stress.
  • Provides insights into age-related digestive changes for clinical and research purposes.
