Renal Failure, Glomerulonephritis and Morbid Obesity: Improvement after Rapid Weight Loss following Laparoscopic Gastric Bypass

There is experimental evidence but very few human studies that suggest a role for obesity in the formation and progression of some glomerular lesions. We report the case of a morbidly obese male with hematuria and proteinuria that was subsequently diagnosed with renal failure which required dialysis. Histological findings of the renal biopsy performed during a laparoscopic gastric bypass are presented. His renal failure resolved with the weight loss.
