title: Bariatric surgery for morbid obesity: risks and benefits in chronic kidney disease patients.
abstract: Obesity is one of the most preventable causes of morbidity and mortality of the 21st century. Chronic kidney disease (CKD) has been a largely overlooked consequence of obesity; however, accumulating evidence elucidates the association. Obesity is at the core, promoting a cascade of secondary pathologies including diabetes, dyslipidemia, inflammation, hypertension, and the metabolic syndrome; these comorbidities constitute great risk for CKD. With the diagnosis of CKD, there is an increased threat of cardiovascular disease and the attendant increase in morbidity and mortality rates. Substantial weight loss in the obese population can be effectively achieved and maintained through bariatric surgery, which confers major health benefits by producing resolution or improvement of obesity-related comorbidities. This surgical procedure presents an early hazard of acute on chronic kidney failure, which is offset by a potential improvement in the risk of CKD progression with anticipated improvement in hypertension, diabetes, and CKD risk factors. Future research is needed to describe the clinical course and risks and benefits of bariatric surgery in the CKD population.
