Abstract

Excessive ingestion of caffeine can induce hypokalemia, which affects the neuromuscular system and can lead to paralysis. A 24-year-old woman, gravida 3, para 2-0-0-2 at 33 weeks' gestation presented with muscular paralysis and hypokalemia secondary to drinking 6 to 7 L of cola per day with little other oral intake. After potassium replacement and stopping caffeine ingestion, the symptoms resolved quickly. The physiologic changes of pregnancy might potentiate the effect of caffeine on serum potassium concentration.
