Are Kidney Stones Caused by Sleep Apnea?

One of my patients who is doing well after sleep apnea surgery emailed me a list of all the improvements just a few weeks out, and at the end, just happened to mention that he expects his kidney stones to be eradicated as well. I didn’t give it much thought, since treating sleep apnea and UARS can help almost anything, but when I went to the literature, I found a study which showed that that sleep apnea can be a direct cause of kidney stones. What the authors showed was that uric acid excretion by the kidneys is increased in people with kidney stones. After treatment with CPAP, uric acid levels normalized.

This finding is not surprising at all, since obstructive sleep apnea is linked directly or indirectly to almost every chronic medical condition that modern people suffer from.

You would think that all patients who suffer from kidney stones would get screened for obstructive sleep apnea, but as far as I can tell, doctors haven’t changed their thinking about kidney stones at all. The same thing happened after a study showed that frequent nighttime urination could be cured by treating an underlying sleep-breathing problem. Again, no major changes in the way nocturia and urinary frequency is handled.

Is there anyone out there whose kidney stone frequency improved after sleep apnea treatment?

  1. Hi Dr. Steven Park,

    OSA is just like a car air chambers for take air for combustion in pistons to works. if not enough air from the passages with filter air there will be complications. For examples: heart swollen, blood viscosity that causes strokes, brain damages and many more. The kidney stones are just like the car did not have enough of air for correct combustion to burn the fuels. if not enough oxygen the incomplete bio-carbon compound will be left as stone like in the kidney over the years. Oxygen, Oxygen, Oxygen!

    Cheers,

  2. My husband has suffered with kidney stones since 1991. He is treated about 4 times a year for stones with lipo and recently had to have a stent bc the lipo didn’t work.

    He just had a sleep study done last week went back in for the CPAP machine.

    By no means do i understand the medical field but i told him if sleep apnea has something to do with blood circulating to your organs perhaps this has something to do with your kidney stones!!!!

    So only time will tell and it’s going to be interesting to see if he forms more stones.

    We have not received his complete report on the sleep study but that will be interesting to see. He snored all the time even in nap mood. He also moved all night long. So i didn’t get sleep either.

  3. I’m 47 and have never had kidney stones in my life until two weeks ago. I’ve been on a cpap since August of last year. I feared the calcium build up in my humidifier was somehow adding to the cause of the kidney stone occurrence despite never passing it. However, I was reminded by my wife of over eating blueberries.
