The classic PCOS symptom of excess weight may increase the risk of developing painful kidney stones.
Researchers found women who weighed more than 220 pounds were 90% more likely to develop kidney stones than those who weighed less than 150 pounds. Women who gained more than 35 pounds since they were 21 years old also had a 39% to 82% higher risk of kidney stones.
Kidney stones are made of salts, minerals, and other substances normally found in urine. When the normal balance of water and other substances is out of balance, such as from dehydration, these substances stick together and build up to form stones. As the stones pass through the urinary system, they can cause sudden, intense pain, nausea and vomiting, and blood in the urine.
Researchers estimate that 5% of women develop kidney stones during their lifetime, and over $2 billion is spent each year in the U.S. on treating the painful condition.
