Micronutrients & recovery
Obesity increases the risk of nephrolithiasis (kidney stones) through mechanisms including lower urine pH, increased urinary oxalate, uric acid, and sodium excretion, as well as insulin resistance.
Obesity increases your risk of kidney stones by changing your urine chemistry (making it more acidic and increasing stone-forming minerals). Maintaining a healthy weight helps normalize these urinary factors and reduces stone risk.
GoodSupportsHIGH confidence
Obesity is associated with a number of risk factors contributing to the higher incidence and prevalence of nephrolithiasis. Higher body weight is associated with lower urine pH and increased urinary oxalate, uric acid, sodium and phosphate excretion.
