Metabolic Syndrome and Chronic Kidney Disease Dynamics

Metabolic syndrome comprises a constellation of interrelated disturbances—including central obesity, insulin resistance, dyslipidaemia and hypertension—that together accelerate vascular damage and predispose to end-organ injury. Chronic kidney disease (CKD) often develops insidiously in individuals with metabolic syndrome as early glomerular hyperfiltration and microalbuminuria progress towards sustained declines in estimated glomerular filtration rate (eGFR). Underlying mechanisms span heightened oxidative stress, low-grade inflammation, activation of the renin–angiotensin–aldosterone system and podocyte dysfunction, all of which promote glomerulosclerosis and tubulointerstitial fibrosis. Emerging data emphasise that even ostensibly ‘metabolically healthy’ subgroups with obesity exhibit early renal maladaptation, while simple anthropometric measures can aid risk stratification. Together, these insights underscore a dynamic interplay between metabolic derangement and kidney injury and highlight the potential for early intervention to arrest or reverse CKD trajectories on a global scale.

Metabolic Syndrome and Chronic Kidney Disease Dynamics publication trend

The graph below shows the total number of articles in metabolic syndrome and chronic kidney disease dynamics across all publications each year (not limited to Nature Index journals).

Technical terms

Metabolic syndrome: A cluster of metabolic abnormalities—central obesity, hyperglycaemia, dyslipidaemia and hypertension—that collectively elevate cardiovascular and renal risk.

Chronic kidney disease (CKD): Persistent reduction in kidney function or evidence of renal damage, typically defined by eGFR below 60 mL/min/1.73 m2 or markers of kidney injury.

Estimated glomerular filtration rate (eGFR): Calculation of kidney filtration capacity derived from serum creatinine or cystatin C, adjusted for age, sex and body size.

Hyperfiltration: Abnormally increased glomerular filtration rate, often an early adaptive response preceding renal injury.

Microalbuminuria: Elevated excretion of albumin in urine (30–300 mg/day), indicating early glomerular barrier dysfunction.

Insulin resistance: Impaired cellular response to insulin signalling, central to metabolic syndrome and contributory to intrarenal pathophysiology.

Oxidative stress: Imbalance between reactive oxygen species production and antioxidant defences, leading to cellular and tissue damage in the kidney.

Renin–angiotensin–aldosterone system (RAAS): Hormonal cascade regulating blood pressure and fluid balance; its overactivation drives hypertensive and profibrotic changes in CKD.
