I started seeing a nephrologist last year because of a cyst and scarring on my right kidney. All of my labs were perfect during my appointment last august, which is good considering I'm only 26 years old. My eGFR was 123 so my doctor told me that I had great function and he only needed to see me once a year to keep an eye on things.
I've had quite a few health problems over the past year but nothing specifically related to my kidneys, however my most recent lab work shows that my eGFR is now only 83. My specialist didn't fully address the loss of function (and of course I didn't know what questions to ask) but did tell me that it was less than 90% which means I'm in stage 2 kidney disease.
What is the cause of my levels dropping so much? What should I be asking? What can I do to help my kidneys? Any advice would be greatly appreciated!
