Recurrent rhabdomyolysis associated with polydipsia-induced hyponatremia — a case report and review of the literature

Abstract

Rhabdomyolysis involves the breakdown of muscle due to an inciting insult. It has been reported to have many etiologies. Some of the more common causes are trauma and medications. Therapy involves vigorous hydration with a crystalloid or bicarbonate infusion and aims to prevent renal failure caused by the release of myoglobin. This case report describes a patient with a recurrent episode of rhabdomyolysis associated with self-induced water intoxication. He was initially treated with a 3.0% saline infusion, followed by a sodium bicarbonate infusion, with correction of his electrolytes and resolution of the rhabdomyolysis.
