title: [Pseudoaldosteronism in an elderly man believed to be caused by the health food Shin-Gojoshin].
abstract: METHODS
  We report a 67-year-old man in whom pseudoaldosteronism developed following consumption of the health food Shin-Gojoshin. The patient began consuming Shin-Gojoshin in February 2007. His serum potassium level, which was within the normal range until he began consumption, gradually decreased to 3.0 mEq/L. The administration of potassium supplements and spironolactone was initiated. However, his hypokalemia persisted, and in December 2009, he was referred to our hospital for further examination. Laboratory data revealed hypokalemia, metabolic alkalosis, urinary potassium wasting, low plasma renin activity, and a low plasma aldosterone concentration. Pseudoaldosteronism was suspected and he was admitted. Although he reported no history of consumption of other traditional herbal medicines at the initial medical outpatient examination, he reported the consumption of Shin-Gojoshin in a medical interview taken on admission. Discontinuation of Shin-Gojoshin and potassium supplementation on admission successfully normalized his electrolyte imbalance.
  
  
  CONCLUSIONS
  The present case describes the occurrence of pseudoaldosteronism induced by consumption of Shin-Gojoshin. A history of consumption of traditional herbal medicines and other health foods should be obtained, particularly in elderly individuals presenting with symptoms of pseudoaldosteronism.
