What is the prevalence of kidney stones?

Kidney stones are a common condition affecting approximately 1 in 10 adults at some point in their lifetime, with prevalence rates steadily increasing globally. While not considered a rare disease, the recurrence rate for kidney stones is high, and the condition significantly impacts quality of life through severe pain and potential urinary complications.

Is the prevalence of kidney stones increasing?

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the prevalence of kidney stones in the United States has risen significantly over the past few decades. Epidemiological data suggests that approximately 11% of men and 6% of women will experience kidney stones during their lifetime. Because many small stones pass without medical intervention, true prevalence is likely higher than clinical records suggest due to underdiagnosis.

Who is most at risk for developing kidney stones?

While kidney stones can occur at any age, they are most common in adults between the ages of 30 and 50. The condition exhibits distinct demographic patterns:

• Gender: Men are statistically more likely to develop kidney stones than women, though the gap is narrowing.


• Geography: Prevalence is often higher in warmer, arid climates, likely due to chronic mild dehydration.


• Ethnicity: In the U.S., higher rates have been observed in Caucasian populations compared to other groups, though dietary and lifestyle factors play a major role.


• Recurrence: Approximately 50% of people who have had one kidney stone will develop another within 5 to 10 years without preventative measures.

Why is accurate data on kidney stones difficult to track?

Tracking the exact prevalence of kidney stones is challenging because many individuals manage small stones at home without seeking emergency care or formal diagnosis. Furthermore, the DiseaseMaps.org community currently supports 13 people with kidney stones; while this is a small sample, it highlights the real-world burden of chronic stone formers who seek peer support for managing recurrent episodes and dietary adjustments.

Next steps

• Consult a urologist to determine the chemical composition of your kidney stones through metabolic testing.


• Increase daily fluid intake to maintain a urine output of at least 2 liters per day.


• Join a support group or the DiseaseMaps.org community to share experiences with others managing chronic kidney stones.


• Discuss dietary modifications, such as limiting sodium and oxalate, with a registered dietitian specializing in nephrology.
