Exercise-associated Hyponatremia
A 30 year-old female was BIBA to the ED following a seizure. She was running a marathon in hot weather. Nearing the end, after 5 hours running, she was seen fall to the ground and had a generalised tonic-clonic seizure.
Sodium
Sodium is the major positively charged Cation in ECF. It determines ECF volume. Major intravascular ion to affect osmolality…..an acute increase or decrease in serum sodium will produce an increase or decrease in serum osmolality.
SIADH
Syndrome Of Inappropriate ADH secretion (SIADH) is hyponatraemia due to an increase in concentration of ADH inappropriate to the current osmotic or volume status. The differential diagnosis includes ADH analogues
Hyponatraemia
Hyponatraemia: common problem in ICU (30% of patients have a Na < 134mmol/L)
Hypernatraemia
Hypernatraemia can be caused by a number of critical illnesses: water depletion (decreased intake, hypotonic fluid loss – renal/non-renal); solute excess (Na+ or other)
SIADH DDx
SIADH = Syndrome of inappropriate antidiuretic hormone secretion. Important cause of HYPOnatraemia

Exercise Associated Hyponatraemia
A recent coroner’s finding about the death of a Tasmanian bushwalker has reinforced the need for awareness of Exercise Associated Hyponatraemia, particularly in those participating in prolonged exercise and ultra-endurance events. What is EAH? What causes EAH? Exercise associated…
