Obesity is highly prevalent in patients with chronic kidney disease (CKD), as it contributes to or accelerates the progression of kidney disease in this at-risk population and is frequently a barrier to kidney transplantation. Patients with renal failure have unique dietary needs due to various metabolic disturbances resulting from altered processing and clearance of nutrients. They also frequently present with physical disability, resulting in difficulty achieving adequate weight loss through lifestyle modifications. Therefore, kidney transplant candidates may benefit from bariatric surgery, particularly sleeve gastrectomy (SG) as the safest, most effective, and long-lasting weight loss option, to improve comorbidities and access to transplantation. However, concerns regarding nutritional risks post-bariatric surgery prevent broader dissemination of SG in this population. No specific guidelines tailored to the nutritional needs of patients with CKD undergoing SG have been developed. Moreover, appropriate monitoring strategies and interventions for muscle loss and functional status preservation, a major concern in this at-risk population, are unknown. We aimed to summarize the available literature on the nutritional requirements of patients with kidney failure seeking SG as a bridge to transplantation. We also provide insight and guidance into the nutritional management pre- and post-SG.Copyright © 2023. Published by Elsevier Inc.
