However kidney stones can be common and there are simple ways to help prevent them even once you have them again. Here are some strategies that may help:
1. Drink enough water. A 2015 meta-analysis of the National Kidney Foundation found that people who produced 2 to 2.5 liters of urine per day were 50% less likely to develop kidney stones than those who produced less. It takes about 8 to 10 8-ounce glasses (about 2 liters) of water daily to produce that amount.
2. Discard high oxalate foods. Foods that include spinach, beets and almonds obviously increase oxalate levels in the body. However, small amounts of low oxalate foods, such as chocolate and berries, are fine.
3. Enjoy some lemons. Citrate, a salt in citric acid, binds calcium and helps prevent stone formation. "Studies have shown that drinking a cup of lemon juice diluted in water each day, or juice of two lemons, can increase urinary citrate and reduce the risk of kidney stones," Dr. Eisner says.
4. See sodium. A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. Federal guidelines suggest limiting the total daily sodium intake to 2,300 mg (mg). If sodium has contributed to kidney stones in the past, try reducing your daily sodium to 1,500 milligrams.
5. Cut back on animal protein. Eating too much animal protein, such as meat, eggs, and seafood, increases uric acid levels. If you are prone to stones, limit your daily intake of meat to an amount that is no larger than a pack of cards.
