Highlights
Polyuria is a condition characterised by excess urine output, defined as more than 3 litres per day in an adult and 2L/m2 in children
The other three major causes of polyuria are due to water diuresis including primary polydipsia, central diabetes insipidus (CDI) and nephrogenic diabetes insipidus (NDI)
If the urine osmolality is less than 300 mOsm/kg it is likely that the aetiology of the polyuria is either DI or primary polydipsia
Summary
A good night’s sleep after two decades: a case report of idiopathic central diabetes insipidus.
