ABSTRACT
We present a case of a young man with a new-onset supraventricular arrhythmia accompanied by polyuria and natriuresis with subsequent renal salt-wasting causing hypovolemic hyponatremia. Resolution of the electrolyte imbalance occurred only after successful atrial flutter ablation.

Here, we present a case of an older man presenting with worsening confusion. Laboratory tests showed serum sodium of 120 mmol/L with severe hypothyroidism and renal salt wasting that improved with treatment of hypothyroidism, normalising the serum sodium.

Sjogren's syndrome is an autoimmune disease associated with xerostomia and xerophthalmia. The association of Sjogren's with hyponatremia has rarely been reported and has been attributed to syndrome of inappropriate antidiuretic hormone secretion. Here, we report a case of polydipsia secondary to xerostomia as a cause of chronic hyponatremia in the setting of Sjogren's syndrome. Analysis of the patient's medical record, including medication reconciliation and dietary habits, revealed several underlying causes of her recurrent hyponatremia. A thorough review of the patient's clinical history and good bedside examination may reduce prolonged hospitalizations and improve the quality of life of a hyponatremic population of patients who are predominantly elderly.
