Clinical Observation: Hyponatremia Associated With Diuretic Use and Urinary Retention in an Older Man

This clinical observation described an 80-year-old man who developed hyponatremia, likely due to a combination of diuretic use, low solute intake, excessive water consumption, and possibly urinary retention. The patient was treated with water restriction and demeclocycline, leading to an improvement in his serum sodium levels and symptoms. The case highlighted the risks associated with thiazide diuretics and excessive water intake in older adults, emphasizing the need for caution in managing such patients. Urinary retention was also considered a potential contributing factor to hyponatremia in the elderly.
