Résumé
Diabetic kidney disease (DKD) is a primary cause of chronic kidney disease and end-stage renal disease, as well as one of the most common microvascular consequences of diabetes mellitus. Obesity, as a metabolic disease, has a substantial impact on the onset and progression of DKD. Epidemiological studies have revealed obesity is a risk factor of DKD and end-stage renal disease, which can promote the occurrence and progression of DKD through various mechanisms, including alterations in hemodynamics, metabolic regulation, and chronic inflammation. Clinical researches also have demonstrated the importance of various weight loss interventions in the prevention and management of DKD. Therefore, gaining a deeper understanding of the correlation between obesity and DKD will contribute to improving the prognosis and quality of life of individuals with diabetes mellitus. The paper reviews the relationship between obesity and DKD on the epidemiological characteristics of obesity and DKD, the potential mechanism of obesity affecting DKD and the influence of obesity intervention on DKD.
