Hypocalemic Myopathy Due to Excessive Cola Consumption

A 25-year-old man was admitted to our emergency department (ED) with progressive paralysis in both upper/lower extremities. His serum potassium level was very low. Laboratory testing ruled out renal potassium wasting. A dietary history revealed that he had been consuming 2-4 liters of cola per day for six years. We present a case of hypokalaemic myopathy induced by chronic cola consuming.
