Psychogenic polydipsia

Patients with polydipsia and hyponatremia require vigilant monitoring of their electrolyte and fluid status.

Active treatment of patients with symptomatic hyponatremia necessitates daily measurements of serum sodium to avoid rapid correction and ensuing risk of central pontine myelinolysis.

After acute treatment, follow-up is generally required in case of recurrence, especially during periods of exacerbation of psychosis.

Regular patient weights can be used to determine water intake diurnally.
