Kidney stones are a common and painful condition that affect about 1 in 10 people each year. In a recent interview, urologist Dr. Brenton Winship of CommonSpirit Health discussed the key facts about kidney stones, including the most common causes, telltale symptoms, and effective prevention strategies.

Why it matters

Kidney stones can be debilitating, causing severe back pain, nausea, and disruption to daily life. Understanding the risk factors and preventive measures is crucial, as having one stone increases the chances of developing more in the future.

The details

Most kidney stones are made of calcium, though there are several types. While men have historically been more prone to kidney stones, women have nearly caught up in recent years. Age is a factor, with risk increasing after 50. Geography also plays a role, with warmer climates like the southern U.S. dubbed the 'stone belt' due to higher dehydration rates. Conditions like diabetes can also raise the risk. The hallmark symptom is severe back pain, often accompanied by nausea, caused by a stone blocking the flow of urine and creating pressure in the kidney.

  • Kidney stones have become increasingly common in recent years.
