A 23-year-old G2P1A0 woman was admitted to an obstetrics unit at 32 weeks of gestation after a routine outpatient laboratory workup revealed severe hypokalemia that failed to resolve despite potassium replacement. She reported some nausea and loose stools but denied vomiting or frequent watery diarrhea. She denied ingestion of licorice and family history of hypertension or hypokalemia. Her medical history was significant for hypokalemia and gestational hypertension leading to induction of labor and delivery at 37 weeks of gestation during a previous pregnancy approximately 2 years earlier.
