Obesity has continued to emerge as a worldwide pandemic and has been associated with a significant increase in associated comorbidities. These include well-known conditions such as hypertension and diabetes, as well as lesser-known conditions such as obesity-related glomerulopathy (ORG). The main etiology of ORG is podocyte damage, but contributing theories include dysfunctional renin-angiotensin-aldosterone system activation, hyperinsulinemia and lipid deposition. Recent advances have made strides in understanding the complex pathophysiology of ORG. The key to treating ORG is weight loss and proteinuria reduction. Lifestyle modification, pharmacological interventions and surgery are mainstays of management. A special focus on obese children is required, as childhood obesity tracks into adulthood and primary prevention is key. In this review we discuss the pathogenesis, clinical features and established and newer treatment modalities of ORG.
