How can i prevent kidney stones comming back?

Three General Rules: Stones form for two reasons: too much of something in the urine that promotes stone formation, or not enough of something that prevents them. 1. Hydration with 80-100 oz of water/day helps to reduce the risk, no matter the composition of the stone. 2. Limit sodium(salt) intake to 1400-1600 mg/day 3. Limit animal protein intake to < 10 oz/day, as uric acid (broken down from meat) promotes stones.
