Elderly individuals face increased hypernatremia risk due to aging kidneys and body changes. This review emphasizes iatrogenic causes and outlines management strategies for this electrolyte imbalance.

Area of Science:

  • Gerontology
  • Nephrology
  • Internal Medicine

Background:

  • Aging is associated with physiological changes impacting fluid and electrolyte balance.
  • Elderly patients exhibit altered renal function and body composition, increasing susceptibility to hypernatremia.
  • Iatrogenic factors significantly contribute to the development of hypernatremia in older adults.

Purpose of the Study:

  • To review the pathophysiology and etiology of hypernatremia in the elderly.
  • To highlight the role of iatrogenic factors in hypernatremia development.
  • To provide a rational approach and clear guidelines for managing hypernatremia in geriatric patients.

Main Methods:

  • Literature review of pathophysiology and etiology of hypernatremia.
  • Emphasis on iatrogenic causes.

  • Discussion of management strategies and treatment guidelines.

    • Main Results:

    • Age-related changes in renal function and body composition predispose the elderly to hypernatremia.
    • Iatrogenic factors are a critical consideration in the etiology of hypernatremia.
    • A structured approach to management is essential for effective treatment.

    Conclusions:

    • Hypernatremia is a significant risk in the elderly due to physiological aging.
    • Understanding iatrogenic contributions is key to prevention and management.
    • Evidence-based guidelines facilitate rational and effective treatment of hypernatremia in this population.
