Physical Activity & Diet Linked to Kidney Stones
(Ivanhoe Newswire) –Researchers have found that even small amounts of physical activity may decrease the risk of developing kidney stones, and consuming too many calories may also increase risk.
Mathew Sorensen, MD (University of Washington School of Medicine, and the Puget Sound Department of Veterans Affairs) and his colleagues conducted a study, which involved more than 84,000 women, to evaluate whether energy intake and energy expenditure relate to kidney stone formation.
After adjusting for multiple factors like BMI, the researchers found that physical activity was associated with up to a 31 percent decreased risk of kidney stones. “Even small amounts of exercise may decrease the risk of kidney stones—it does not need to be marathons, as the intensity of the exercise does not seem to matter,” Dr. Sorensen was quoted as saying.
Women could get the maximum benefit by performing 10 metabolic equivalents per week, which is the equivalent of about three hours of average walking, one hour of moderate jogging, or four hours of light gardening. Researchers also discovered that consuming more than 2200 calories per day increased the risk of developing kidney stones by up to 42%.
