Can Bariatric Surgery Be a Surgical Treatment to Prevent the Progression of Chronic Kidney Disease?

Obesity is a serious worldwide health problem causing numerous obesity-related comorbidities such as hyperlipidemia, hypertension, diabetes, and cardiovascular dysfunctions. Recently, many studies indicate that obesity is strongly related with high rate of renal lesions and reducing weight with surgical intervention can improve renal parameters in obese patients, but the effect of bariatric surgery on obesity-induced chronic kidney disease (CKD) is hardly documented. This review study shows that bariatric surgery demonstrates beneficial reduction in proteinuria and albuminuria leading to improve both glomerular hyperfiltration and chronic kidney disease in obese population. Yet, bariatric surgery is not a definite treatment of choice for the obese patients with CKD because of lack of evidence explaining the risk of complications following bariatric surgery and clarification on estimating glomerular filtration rate (eGFR) in obese patients. Future, high quality studies with a long term follow up are required to determine the effective durability of bariatric surgery on obese-related CKD patients
