Summary

Managing water balance in elderly patients with hyponatremia or hypernatremia is critical. Impaired thirst, kidney function, and hormonal regulation increase risks, necessitating a systematic clinical approach.

Area of Science:

  • Geriatrics
  • Nephrology
  • Internal Medicine

Background:

  • Water homeostasis abnormalities are challenging in elderly patients.
  • Age-related changes and chronic diseases impair water metabolism.
  • Elderly patients are susceptible to hyponatremia and hypernatremia.

Purpose of the Study:

  • To highlight the importance of understanding hyponatremia and hypernatremia pathophysiology in the elderly.
  • To emphasize the need for a systematic clinical approach to water and sodium imbalances.
  • To underscore the role of iatrogenic factors in elderly patients' fluid balance.

Main Methods:

  • Systematic evaluation of water and sodium problems.
  • Comprehensive history and physical examination.
  • Directed laboratory tests for diagnosis.

Main Results:

  • Thirst sensation, renal function, and hormonal regulation are often impaired in the elderly.
  • Elderly patients are prone to morbid and iatrogenic salt and water events.
  • Iatrogenic interventions and care lapses frequently disrupt fluid balance.

Conclusions:

  • Clinicians must be aware of the pathophysiology of hyponatremia and hypernatremia in the elderly.
  • A systematic approach is essential for diagnosing and managing water and sodium imbalances.
  • Recognizing iatrogenic causes is crucial for preventing complications in institutionalized elderly patients.
