I am 44 yrs old. I had a surgery about 3 months ago and noticed my GFR was low. The Dr preforming the surgery said all my other labs were in normal range and that it probably wasn't an accurate reading. My family Dr said your GFR should be above 60. I have tried doing research to see what I can do to improve my GFR and every site is so confusing. I just had another blood test done and I am waiting to see what my GFR is and I was wondering if anyone else has gone through this and if your numbers have improved? Thank you for any input.
