A Taiwanese study found that newly diagnosed nephrolithiasis (kidney stones) was 19 percent more common in patients with ankylosing spondylitis compared to people without the disease.
The researchers noted several possible reasons for this: most kidney stones contain calcium, and people with severe ankylosing spondylitis have altered calcium and vitamin D metabolism as well as an increased risk of inflammatory bowel disease, which can increase their absorption of calcium. The use of anti-inflammatory drugs may also contribute to kidney stones.
How can you Prevent Kidney Stones?
One in 10 people will develop kidney stones in their lifetime, according to the National Kidney Foundation. But there are some easy ways to reduce your risk or, if you’ve had stones in the past, prevent new ones from forming:
- Drink up. Stay hydrated by drinking plenty of water, especially if you’re doing exercise that makes you sweat.
- Don’t reduce calcium. It’s a common misconception that lowering calcium intake reduces kidney stone risk. Actually, low calcium diets increase your risk. Cut back on sodium instead.
- Make lemonade. Studies show lemonade, limeade and other fruits and juices high in citrate lower the risk of stones. Just watch the sugar!
- Cut back on meat. Animal protein contains acid that can reduce citrate in the urine, and citrate helps prevent kidney stones.
- Try DASH. The Dietary Approaches to Stop Hypertension (DASH) diet can reduce the risk of kidney stones. This diet is high in fruits and vegetables, moderate in low-fat dairy products, and low in animal protein.
- See a dietician. A dietician or nutritionist can help you plan meals and make easy swaps to lower your risk of stones based on the types of stones you’ve had in the past.
