Having kidney stones increases your risk of getting them again unless you actively work to prevent them. This means taking medications prescribed to you for this purpose, and watching what you eat and drink.
Tips that will help include:
Drink at least twelve glasses of water daily
Drink citrus juices, such as orange juice
Eat a calcium-rich food at each meal, at least three times a day like milk, curd, tofu, buttermilk etc.
Limit your intake of animal protein
Eat less salt, added sugar, and products containing high fructose corn syrup
Avoid foods and drinks high in oxalates and phosphates like chocolates, beet, spinach, sweet potato, tea etc.
Avoid eating or drinking anything which dehydrates you, such as alcohol.
