Obesity Promotes Kidney Stones

Friday, 25 May 2012 01:33 PM




The number of Americans with kidney stones has nearly doubled over the past two decades, according to a new University of California-Los Angeles study that suggests the nation’s growing obesity epidemic may be to blame.
"While we expected the prevalence of kidney stones to increase, the size of the increase was surprising," said lead researcher Dr. Charles D. Scales, with the David Geffen School of Medicine at UCLA. "Our findings also suggested that the increase is due, in large part, to the increase in obesity and diabetes among Americans."
The study, presented at the 2012 American Urological Meeting in Atlanta and slated for publication in the journal European Urology, compared the number of cases of kidneys stones reported in 1994 to those from 2007-2010.
Reports were taken from the National Health and Nutrition Examination Survey (NHANES), conducted by the Centers for Disease Control and Prevention to assess the health and nutritional status of adults and children in the United States.
Scales and his colleagues examined records from 12,110 people and found nearly 1 in every 11 people had a kidney stone from 2007 to 2010. In 1994 the rate was 1 in 20. The researchers were able to track a rise in obesity, diabetes and gout over that period – all of which increase the risk of kidney stones.
"People should consider the increased risk of kidney stones as another reason to maintain a healthy lifestyle and body weight," said researcher Dr. Christopher S. Saigal. "But physicians need to rethink how to treat, and more importantly, prevent kidney stones," by helping patients maintain a healthy diet and body weight.
"Imagine that we only treated people with heart disease when they had chest pain or heart attacks, and did not help manage risk factors like smoking, high cholesterol, or high blood pressure," said Scales. "This is how we currently treat people with kidney stones. We know the risk factors for kidney stones, but treatment is directed towards patients with stones that cause pain, infection, or blockage of a kidney rather than helping patients to prevent kidney stones in the first place."
