True hypernatraemia of this magnitude is usually
caused by water depletion (decreased water
intake/icreased water losses). You have mentioned DI,
what was its nature, was it cranial or nephrogenic?,
has this been treated? Has the hypernatraemia
developed over days (give U/Es values over few days)?
what was the fluid balance like over the last week?
What is her urine osmolality?
Salt excess ( via i.v fluid and antibiotics)can
obviously compound the picture, is the patient
oedematous?
Answers to all these questions are essential to find
out cause of hypernatramia.
