Kidney stones are among the most painful medical conditions that I treat. They are usually calcium based and about 50% of people who have a stone will get another within 5 years. The best way to prevent stones is to make dietary changes. Urologists recommend drinking 12-8 ounce glasses of water per day. It is also recommended to avoid soft drinks, especially colas. This is because they contain phosphoric acid which can increase the risk of getting stones. Calcium supplements have also come under fire recently. I have written about the risks of not only kidney stones, but also heart disease and macular degeneration with a lot of calcium supplements. However, DIETARY CALCIUM has never been associated with any side effects. Certain foods like black tea and chocolate can raise oxalates which also cause stones.
When dietary changes aren’t enough, we sometimes will add a diuretic which is cheap and decreases calcium excretion in the kidneys. (No calcium-no stones) Another product, potassium citrate will decrease the acidity of the urine, which will also decrease stone formation.
