Gitelman's syndrome presenting as recurrent paralytic ileus due to chronic renal tubular K+ wasting.

Gitelman' syndrome, although a relatively frequent cause of chronic hypokalemia in adults, is rarely diagnosed correctly. It is frequently confused with overt diuretic abuse or Bartter's syndrome. We describe a 60 year man with 2 year history of recurrent paralytic ileus attributed to recurrent hypokalemia. Investigations in this patient revealed hypokalemia, metabolic alkalosis, hypocalciurea, and hypomagnesemia a tetrad diagnostic of Gitelman's syndrome. The peculiar clinical features of this condition and its management are discussed.
