Bartter syndrome (BS) is a hereditary disease, with an autosomal recessive or 
autosomal dominant mode of transmission. It is characterized by salt wasting 
hypochloraemic, hypokalaemic metabolic alkalosis and hyperreninaemia with normal 
blood pressure. The primary defect is in the thick ascending limb of loop of 
Henle (TAL). Herein, we report a case that had typical features of BS like 
severe dehydration, severe hypokalaemia, metabolic alkalosis and failure to 
thrive but had normal aldosterone level which is very uncommon.
