Abstract
Introduction
Serological hyponatraemia has a number of different aetiologies. Although laboratory values may vary, the normal range for serum sodium is between 133-147mmol/L. The aetiology of hyponatraemia can be sub-divided into 3 broad categories- hypervolaemic hyponatraemia, normovolaemic hyponatraemia or hypovolaemic hyponatraemia (1). Serum sodium levels may also appear falsely low if the blood sample is lipaemic or has high protein content.
In addition to conditions associated with anti-diuretic hormone (ADH) disturbance, hyponatraemia can be caused by malnutrition in both children and adults and may become a chronic state for which replacement therapy has to be administered judiciously in order to avoid cerebral oedema.
