Association between obesity and chronic renal disease

A higher frequency of chronic renal disease is observed in obese patients, suggesting a pathogenic association between both conditions. Obesity unmasks clinical manifestations of chronic kidney disease such as high blood pressure, which may accelerate its progression. Obesity also promotes hyper filtration and the appearance of microalbuminuria, activates the renin-angiotensin-aldosterone system and is associated with high levels of pro-inflammatory cytokines. Therefore weight reduction may slow the progression of chronic renal disease and reduce its associated cardiovascular risk factors.
