I'm new and have been doing some reading here trying to better understand kidney issues in general.
I realize that an eGFR of 51 is far from an emergency but what I'm concerned about is the drop in just a year's time (from 89 to 51). My serum Creatinine went from .79 to 1.2 during this same time. Also, my CRP was over range, showing inflammation. I'm not diabetic and do not have HBP. My doctor has referred me to a Nephrologist and my first appointment will be coming up soon.
My question is whether it's possible for the last eGFR to be a 'fluke' of some kind? Can hypothyroidism cause something like this? If so, is it reversible? A couple of months prior to this test I had to switch thyroid meds because my FT3 had gone way below range and had me feeling very badly, which is why I ask.
I've had some minor changes in urine--increased frequency, especially at night; and occasionally have a bit of foamy bubbles or cloudiness. My eyes have become puffy underneath with dark circles, something new for me.
I've also been having a lot of flank pain, mostly on one side. The pain tends to be constant and will flare up for a couple weeks then lessen until the next time, and is something I've had over the years but not as painful as it's been lately. I don't believe it was a kidney infection because I had no fever and no other symptoms, just the pain. Years ago I was told a few times that I had protein and blood in my urine but the doctor was never concerned and chalked it up to my lupus (which has never affected major organs before).
Anyways, I'm just curious if this sounds familiar to anyone. Thanks in advance for any input!
