sudden headache
vomiting
visual disturbances
hormonal dysfunction

SIADH features
reduced sodium
urine osmolality is raised
reduced serum osmolality - euvolemic
DI features
large volumes of dilute urine
low urine osmolality
nocturia and thirst
serum osmolality is raised but urine is dilute
dilute urine
concentrated serum osmolality
> 700 is relevant why
desmopressin given and urine does not get more concentrated
> 700 urine osmolality rules out DI at water deprivation
NI DI adh production is fine kidney just can’t respond
SIADH management?
treat cause
immediate fluid restriction for the hyponatraemia
