Resolution of nephrotic syndrome after successful bariatric surgery in patient with biopsy-proven FSGS

Abstract

The incidence of obesity-related nephropathy (ORG) is increasing with the growing incidence of obesity. ORG is associated with morbid obesity, proteinuria and renal biopsy findings of focal global and segmental glomerulosclerosis (FSGS), which can be associated with significant renal impairment. Weight reduction is associated with improvement of ORG, however, conservative measures aiming at long-term weight reduction are difficult to achieve. Bariatric surgery is the most effective way of achieving long-term weight reduction. We present a case of ORG with nephrotic-range proteinuria and FSGS on renal biopsy. Following bariatric surgery, patient achieved successful weight reduction with significant decrease in proteinuria and stabilization of renal function.
