Gallstones and kidney stones are not related. They form in different areas of the body. If you have a gallstone, you are not necessarily more likely to develop kidney stones. For unknown reasons, the number of people in the United States with kidney stones has been increasing over the past 20 years. White Americans are more prone to develop kidney stones than African Americans.
Stones occur more frequently in men.
Kidney stones strike most typically between the ages of 20 and 40. Once a person gets more than one stone, others are likely to develop. Doctors do not always know what causes a stone to form. While certain foods may promote stone formation in people who are susceptible, scientists do not believe that eating any specific food causes stones to form in people who are not susceptible. A person with a family history of kidney stones may be more likely to develop stones.
