  • hyponatraemia with ECF volume excess can arise in a variety of diseases
    • causes of hypervolaemic hyponatraemia include:
      • CHF
      • liver cirrhosis
      • nephrotic syndrome
      • renal failure
      • excessive water intake
    • volume excess is generally diagnosed clinically from the history, physical examination and laboratory results
      • patients with clinical signs of volume overload (subcutaneous oedema, ascites, pulmonary oedema)
        • should be considered to have hypervolaemia unless there are alternative explanations for these findings
