Is there a link between hydration status, water intake and kidney stones risk?
New findings conducted by the US National Center for Health Statistics in 8195 adults aged 20 years old or older suggest ensuring 2.5 L/day of water (about 10 glasses) is associated with reduced kidney stones risk.
✔ Increasing water intake reduces kidney stones risk by decreasing markers of insufficient hydration.
✔Water is an effective and safe intervention for both primary and secondary prevention of kidney stones.
✔ The amount of water is important: there is a dose–response relationship between daily water intake and kidney stone formation (the lowest risk is observed when daily fluid intake is 2.5-3 L).
