Bartter's syndrome is characterized by hypokalemia, metabolic alkalosis, hyperreninemia and
secondary hyperaldosteronism without hypertension and edema. Histologically, existing hyperplasia of
the juxtaglomerular cell occurs mostly in childhood or adolescence, and initial presentation in
patients over 40 years old of age is very rare. It has been recorded that Bartter's syndrome is
associated with glucose intolerance, but not with overt diabetes mellitus. Whether this association is
coincidental or causal is uncertain, although hypokalemia can cause glucose intolerance. We
experienced a case of Bartter's syndrome in 44 years old non-insulin dependent diabetic woman.
She improved with potassium supplements along with combination of prostaglandin synthetase
inhibitor and aldosterone antagonist. We report present case with the review of literature.
