CLEVELAND, OH-- Summer just officially started, but kidney stone season began a couple of weeks ago.
There is usually an increase in the number of kidney stone cases when the weather warms up.
Dr. Manoj Monga from Cleveland Clinic said, "The stone might have formed in the winter. It might have formed two or three years ago, but when they come to the emergency room with pain, which is usually a sign that the stone is moving, it happens more often in the summer than in the winter months."
Researchers have studied urine samples taken in the winter and the summer. They found that the risk of developing kidney stones is higher in the winter because there are typically more calcium in the urine during winter months. Having too much calcium in the urine, which is known as hypercalciuria, can be a risk for kidney stones. The stones may form in the winter and are then dislodged in the summer.
"It might be that in the summer they become more active and with activity that stone starts to move and that's when we find out that the stone is actually there," Monga explained.
Physical activity also protects against stone development, so if you're less active in the winter, your risk for developing a kidney stone increases.
