Kidney stones may form when the normal balance of water,
salts, minerals, and other substances found in urine changes.
Thus patients with kidney stones are often advised to drink
more fluids as a way to prevent future stone formation.
Drink More Fluids - Not Softdrinks!
Now, new research from Brigham and Women's Hospital finds that some beverages may be more helpful than others when it comes to preventing recurrent kidney stones.
Now, new research from Brigham and Women's Hospital finds that some beverages may be more helpful than others when it comes to preventing recurrent kidney stones.
"Our study found that the relation between fluid intake
and kidney stones may be dependent on the type of beverage consumed,"
explained Gary Curhan, MD, ScD, a physician in the Channing Division of Network
Medicine at BWH and senior author of this study. "We found that higher
consumption of sugar-sweetened drinks was associated with a higher incidence of
kidney stones."
The researchers analyzed data from three ongoing cohorts,
the Health Professionals Follow-Up Study (HPFS), and both the Nurses' Health
Study I (NHS I) and II (NHS II). The total analysis involved 194,095
participants over a median follow-up of more than 8 years. Participants in all
the three cohorts had been asked to complete biennial questionnaires with
information on medical history, lifestyle, and medication. Questions on diet
were updated every four years.
The researchers found that participants who consumed one or more sugar-sweetened cola servings per day had a 23 percent higher risk of developing kidney stones compared with those participants consuming less than one serving per week. This was true for consuming sugar-sweetened non cola as well, such as punch. They also found that some beverages, such as coffee, tea and orange juice, were associated with a lower risk of stone formation.
