Obesity Linked to Increased Risk of Kidney Stones Research shows that obese individuals are twice as likely compared to normal weight individuals to suffer from kidney stones. Kidney stones are mineral deposits that solidify and can be painful to pass through the urinary tract. In the study researchers analyzed the medical records of 95,000 people in a national insurance database. There was no difference in the risk of stone formation between obese and severely obese patients. Treatment options, however, differed by weight as obese patients were more likely than normal weight or overweight patients to undergo stone removal treatments as opposed to naturally passing the stone.
