What causes kidney stones?
When there isn’t enough water to dilute the uric acid, a component of urine, the urine becomes more acidic. And this can lead to the formation of kidney stones. A leading cause of kidney stones, regardless of type, is dehydration. Anyone who is prone to kidney stones should pay attention to good hydration. The American Urological Association guideline for medical management of kidney stones recommends that patients who form kidney stones should aim to drink more than 2.5 liters of fluid per day.
