The Kidney Stone rate has doubled in the last 16 years. Doctors believe the cases are linked to obesity.
Researchers at UCLA and the Rand Corporation found that in 1994, one in 20 people had kidney stones, in the years between 2007 and 2010, the rate was one in 11.
They discovered that people who were obese, had diabetes or gout were more likely to be diagnosed with kidney stones.
Kidney stones can be treated, but they can also be prevented by eating healthy and getting a lot of exercise.
