Q

hyponatriemie oorzaak

A

inname of toediening van veel water of verminderde renale waterexcretie (lage eiwitiname, nierfalen, ADH afgifte)

6
Q

appropriate ADH afgifte

A

hyponatriemie wordt veroorzaakt doordat volumeregulatie het wint van osmoregulatie, het wordt dan alleen afgegeven om bloedvolume depletie te corrigeren

Q

inappropriate ADH afgifte

A

ADH afgifte bij lage osmolaliteit; kan door: farmaca, ectopische productie ADH, longaandoeningen, versterkt ADH effect, bijnierinsufficientie
