Obesity and Metabolic Health in CKD

Obesity is a worldwide epidemic with a future projected growth of 40% over 10 years. Obesity increases the risk of diabetes, hypertension, and cardiovascular disease, and it also leads to higher risk of CKD, through both direct and indirect mechanisms. Although obesity is a feature of overnutrition and is associated with poor outcomes in the general population, obese individuals with CKD often display complex metabolic patterns such as sarcopenic obesity, and obesity can be associated with better survival in individuals with advanced CKD. Weight loss interventions are proven to improve glycemic control and cardiovascular risk factors, and successful weight loss is associated with improved albuminuria in patients with preexisting CKD. The long-term effects of weight loss interventions on kidney function and on survival in patients with CKD are less well studied, and hence, such interventions should be individualized.
