Gitelman and Bartter Syndrome in a Patient With Morbid Obesity: A Case Report and Literature Review

We present a case study of a 34-year-old man with morbid obesity and a suspected Bartter-Gitelman spectrum tubulopathy (without genetic confirmation), weighing 135 kg, and with a BMI of 42.5 kg/m², who was referred to the metabolic and bariatric surgery department due to morbid obesity to address abnormal electrolyte levels. The clinical presentation suggested renal tubular salt wasting. Post-sleeve gastrectomy, the patient had sustained and prolonged normalization in his electrolytes without the use of any medications. This provides evidence of a possible relationship between metabolic surgery and renal tubular function. This case supports recognizing a suspected tubulopathy in candidates for metabolic surgery.
