If you are prone to kidney stones, drink plenty of water (6 to 8 glasses per day) to reduce the chances of their formation.
Research suggests that a diet low in sodium and oxalate and high in citrate significantly reduces risk of calcium-based kidney stone formation. Consult with a nutritionist for more information on such diets.
Seek medical attention if kidney stones persist or recur to identify the cause and to prevent new stones from forming.
