“A la croque-au-sel” Syndrome: An unusual Cause of Diet-Induced Hyperkalemia
Abstract
Hyperkalemia, defined as a plasma potassium concentration above 5 mmol/l, is a common electrolyte disturbance1. It is often asymptomatic but may be potentially life-threatening when presenting with severe manifestations including cardiac conduction defects, arrythmias and acute neuromuscular dysfunction. Three main intricate mechanisms are involved in the pathophysiology of hyperkalemia: excessive potassium intake, reduced renal elimination and increased potassium release from the intracellular to extracellular space.
