About 15 months ago, at age 63, I had my first and only kidney stone. I just had another X-ray today and there was no evidence of any kidney stones. So I am wondering if that one kidney stone likely was just an anomaly, or if I am apt to have more in the years to come. At the time of my kidney stone, I had low hemoglobin ( 7.0); it had been well below normal for over a year due to chronic bleeding. Thankfully, that bleeding issue has now finally been corrected. But I am curious if perhaps my kidney stone episode a year ago was a side effect of my chronic bleeding and low hemoglobin.
