Abstract

A 32-year-old woman with a three-year history of muscle weakness and hypokalemia, was admitted to our hospital because of hypokalemic periodic paralysis. Clinical and laboratory findings were consistent with Bartter's syndrome. Although she denied any ingestion of diuretics substantial quantities of furosemide were detected in her urine. She had been drinking health tea which contained about 90 mg of furosemide per teabag daily for five years. Four years after discontinuation of drinking the tea, the hypokalemia was completely ameliorated, but poor renal concentration ability is still present . We conclude that is a case of pseudo-Bartter's syndrome that was caused by long-term ingestion of the health tea supplemented illegally with furosemide, and suspect that such cases may be observed more frequently than currently thought.
