Hello doctor, I am a 43-year-old male. And I work out six days a week. I am in excellent shape. I consistently get my blood work done every four months. I am a kidney stone former and had kidney stones on and off for the last 10 years. I have a few kidney stones on my right side. I had blood drawn two times last month. My GFR was 63, and 65, creatine level was 1.34 and 1.36. Cystatin C was 1.21, and ACR was 0.6. All other blood tests are fine. Based on these results, do you think my kidneys are damaged? Do you think I should cut back on working out?
Hello. Seeing your current report (attachment removed to protect patient identity) there is mild damage to your kidney, and creatinine before four months was also elevated, then it is a slight degree of permanent damage. So the cause of the damage is long-standing bilateral stone can cause gradual damage to the kidney, so it needs evaluation for things, like urine routine, ultrasonography of kidney, test for sugars, blood pressure and if need a kidney biopsy. About workout, you can reduce the frequency of workout but no need to stop completely, if you got a mild degree of permanent damage (CKD), you need to restrict protein intake to 0.7gm/kg/ day, blood pressure monitoring, and kidney stone management. I hope this solved your issue.
