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).
