Abstract:
Obesity is increasing in prevalence across the United States. The surgical therapy for obesity is effective at reducing weight; however, the benefits to renal function are not well described. We report an obese patient with nonnephrotic-range proteinuria that resolved after Roux-en-Y gastric bypass. Evidence suggests that obesity-related renal dysfunction is multifactorial and may be a result of hyperfiltration or increased intra-abdominal pressure. The use of gastric bypass as a permanent solution to obesity may confer a similar benefit to obesity-related renal dysfunction.
