OBJECTIVE: Hypokalemia is a potentially life-threatening electrolyte disturbance in anorexia nervosa and is most frequently caused by purging behavior. We report a case of severe hypokalemia in anorexia nervosa induced by daily ingestion of approximately 20 g of licorice.
METHODS: To confirm the diagnosis of licorice-induced pseudohyperaldosteronism, a re-exposure trial was performed.
RESULTS: Cessation of the licorice intake normalized plasma potassium, renin, and aldosterone levels and the urine cortisol/cortisone ratio. Re-exposure confirmed the diagnosis. The pronounced response to a relatively low daily dose of licorice suggests high glycyrrhizin sensitivity.
CONCLUSION: Patients with anorexia nervosa not only have decreased food intake but also selective and sometimes bizarre eating habits that, in association with increased sensitivity to glycyrrhizin, may cause severe hypokalemia.
