I'm a 36 year old female, not obese, healthy blood pressure, not diabetic.
In 2016 my GFR was 78, in 2018 it was 67, and a couple months ago it was 53. I had a sonogram to make sure I have two kidneys. My primary care doctor referred me to a nephrologist who told me I'm "probably fine." I understand that my numbers are not terrible, by any stretch, but I'm concerned about how they are dropping and that the doctor didn't feel like any follow-up would be necessary.
