Ageing causes hormonal shifts, diseases, and medications that raise the risk of hypernatremia and hyponatremia. Understanding these changes improves fluid disorder management in elderly patients, reducing illness and death.

Area of Science:

  • Gerontology
  • Internal Medicine
  • Nephrology

Background:

  • Ageing is associated with significant physiological changes.
  • Elderly individuals often have comorbidities and polypharmacy.
  • These factors increase susceptibility to electrolyte imbalances, specifically sodium disorders.

Purpose of the Study:

  • To highlight the increased risk of hypernatremia and hyponatremia in the elderly.
  • To emphasize the importance of understanding age-related homeostatic changes.
  • To advocate for improved management of fluid disorders in geriatric patients.

Main Methods:

  • Review of physiological changes with ageing.
  • Analysis of the impact of comorbidities on fluid balance.
  • Examination of medication effects on sodium homeostasis.

Main Results:

  • Hormonal alterations during ageing contribute to fluid dysregulation.
  • Concurrent medical conditions exacerbate the risk of sodium imbalance.
  • Pharmacological agents can significantly influence serum sodium levels.

Conclusions:

  • Age-related physiological shifts, diseases, and medications are key contributors to hypernatremia and hyponatremia.
  • Enhanced awareness of these factors is crucial for effective clinical management.
  • Proactive management of fluid disorders can decrease morbidity and mortality in the elderly.
