Kidney stones can be dissolved by modifying your diet. To dissolve kidney stones, you should reduce your intake of salt. Moreover, you must avoid animal proteins, and oxalate-rich foods. You should also increase your fluid intake, especially water. Drinking plenty of water can help in flushing out the minerals and other substances that can form stones. The more water you drink, the more diluted your urine becomes. This makes it less likely for minerals to crystallise and form stones.
