    Hyperkalemia, a dangerous condition in older adults, often stems from reduced kidney function or certain medications. This study presents cases and a diagnostic approach for high potassium levels in the elderly.

    Area of Science:

    • Nephrology
    • Geriatric Medicine
    • Internal Medicine

    Background:

    • Hyperkalemia is a prevalent and serious electrolyte imbalance in the elderly population.
    • Elderly patients frequently have comorbidities or are on medications predisposing them to hyperkalemia.
    • Reduced renal excretion is a primary mechanism for hyperkalemia in this demographic.

    Observation:

    • Presents three clinical cases of hyperkalemia in elderly individuals.
    • Highlights the role of decreased renal excretion of potassium as the underlying cause.
    • Documents the specific clinical scenarios leading to elevated plasma potassium.

    Findings:

    • Identified decreased renal excretion as the cause of hyperkalemia in the described cases.
    • Demonstrated a correlation between underlying conditions/medications and impaired potassium handling.

  • Confirmed the potential severity of hyperkalemia in elderly patients.

    • Implications:

    • Suggests a straightforward diagnostic strategy for identifying the cause of hyperkalemia in older adults.
    • Emphasizes the importance of considering renal function and medication review in elderly patients with hyperkalemia.
    • Aids clinicians in the etiological diagnosis and management of hyperkalemia in geriatric populations.
