Oct 13, 2025Kidney stones are known for causing severe, often unbearable pain, with sharp discomfort typically radiating from the back and sometimes accompanied by blood in the urine.
These mineral deposits develop when the body isn’t adequately hydrated, leading to a greater risk of crystallization in the kidneys.
Dr. Michael Perttunen, a urologist at Novant Health Davidson Urology, stresses the importance of both water intake and frequent urination to help prevent stones from forming.
He recommends drinking at least 2.5 liters of water daily to dilute minerals in the urine.
Diet is also crucial, with a focus on limiting high-oxalate foods like some teas and coffees, while increasing citrus fruits that provide citrate, which helps block stone formation.
Those with added risk factors can benefit from tailored plans and advanced care options offered through local specialists.
Simple lifestyle changes can dramatically lower kidney stone risks and support better urinary health.
