Abstract:
Hyponatraemia is an exceedingly common condition frequently encountered both in hospital and primary care settings. This medical condition poses unique challenges due to its often subtle and nonspecific symptoms, alongside its diverse array of potential causes. It can result in serious consequences when overlooked or not treated appropriately. Herein, we illustrate the case of a 68-year-old woman who presented with symptomatic hyponatraemia. Although not uncommon, the cause of hyponatraemia in this patient is frequently overlooked but, importantly, is avoidable. This case underlines the necessity of a more watchful approach to prescription of medications, especially in older adults with multiple comorbidities.
