Abstract

There is increasing evidence that obesity, independently from other comorbidities such as diabetes and hypertension, can cause renal dysfunction. While this indolent dysfunction may be asymptomatic, it can render patients more susceptible to renal insufficiency when the kidneys are further injured by other pathological processes. Here, we present a morbidly obese patient whose type-A aortic dissection was complicated by acute renal failure that subsequently progressed into end-stage renal disease. However, his renal function improved dramatically following substantial weight reduction after gastric bypass surgery obviating the need for dialysis and transplantation. The potential mechanisms by which a patient’s obesity may lead to renal dysfunction are discussed. This case and other similar reports suggest that obese patients with renal failure can safely undergo bariatric surgery and that bariatric surgery may have a role in treating chronic kidney disease in select morbidly obese patients.
