As a metabolic disorder, obesity can cause secondary kidney damage, which is called obesity-related glomerulopathy (ORG). As the incidence of obesity increases worldwide, so does the incidence of end-stage renal disease (ESRD) caused by ORGs. However, there is still a lack of effective strategies to prevent and delay the occurrence and development of ORG. Therefore, a deeper understanding and elaboration of the pathogenesis of ORG is conducive to the development of therapeutic drugs for ORG. Here, we review the characteristics of pathological lesions of ORG and describe the roles of lipid metabolism disorders and mitochondrial oxidative stress in the development of ORG. Finally, we summarize the current available drugs or compounds for the treatment of ORG and suggested that ameliorating renal lipid metabolism and mitochondrial function may be potential therapeutic targets for ORG.

Herein, we review the devastating consequences of the worldwide obesity epidemic on kidney health and outcomes. We submit that the obesity epidemic is the most pressing public health crisis facing the nephrology community today. A historical approach has been undertaken, wherein major breakthroughs in the recognition and understanding of obesity-related kidney disease (ORKD) are highlighted.

Obesity-related glomerulopathy (ORG) represents an escalating public health with no effective treatments currently available. Abnormal lipid metabolism and lipid droplet deposition in the kidneys are key contributors to ORG. Cyanidin-3-glucoside (C3G) has shown potential in regulating lipid metabolism and may offer reno-protective effects; however, its therapeutic efficacy and underlying mechanisms in ORG remain unclear.

The definition of hyperfiltration, the main pathogenesis in renal impairment in obesity and diabetes mellitus, is uncertain. Glomerular filtration rate (GFR) declines physiologically with aging, and there is inaccuracy in GFR in obesity due to body surface area (BSA) correction. Here, we defined hyperfiltration using GFR without BSA correction, but with inclusion of aging, and investigated hyperfiltration using this definition and absolute GFR > 125 mL/min.

The incidence of obesity-related glomerulopathy (ORG) is rising worldwide with very limited treatment methods. Paralleled with the gut–kidney axis theory, the beneficial effects of butyrate, one of the short-chain fatty acids (SCFA) produced by gut microbiota, on metabolism and certain kidney diseases have gained growing attention. However, the effects of butyrate on ORG and its underlying mechanism are largely unexplored.
