thanks for your help and only creatine i was taking was what was in bcaas i was taking...and pre-work out. and yes, i did drink ALOT of water..so i thought..never kept track...
results...
-Bun....25H
-Creatinine.....1.39 H
-GFR......if you mean EGFR.....67
-Na (sodium)......140
-K (potassium)......4.5
my test came back at 331 also
what he stated in his note that my blood sugar was slightly high...104, also there was evidence for mild kidney impairment, they are similar to one year, they got slightly higher but not significantly.
-Cl (Chloride)
-CO2
That's a fairly mild renal insufficiency based on your results. My guess is that they'll repeat your labs in a few weeks and then go from there. The most common cause of a renal insufficiency in an otherwise healthy young guy (which I assume you don't have any significant medical problems) is secondary to a fluid volume deficit or dehydration.
BUN (Blood Urea Nitrogen) can be influenced by increased protein intake, but creatinine shouldn't be and is a better indicator of overall renal function. It's important to have both values to correlate the possible etiology. Creatine use will also influence the results a bit through increased intravascular departmental shifting of fluid. Sometimes it can seem like you're drinking enough water, but the overall requirement can be higher than you thought. I wouldn't take anything outside a multivitamin at this time and have you repeat labs done. I'm fairly confident that they'll (BUN/Creatinine) show improvement. If not, you'll be referred to a nephrologist for further testing.
Follow-up for certain to make sure all is well. This is why I ALWAYS recommend guys have baseline lab values to correlate with future testing. Good luck, and let us know how it goes.
Edit: Also when/if kidney function begins to deteriorate, Potassium will be retained through functional loss of the kidney itself, and often hyperkalemia (high potassium) will be noted on the basic chemistry panel. That will vary depending how impaired the renal function is. This really doesn't pertain to your situation here based on what you've posted; I just though I'd comment on it. Your sodium and potassium are completely normal.
