26M lifter with elevated creatinine and trace protein, CKD concern
26M, 5’8”, 190 lbs, looking for opinions because I tend to get health anxiety sometimes. I requested proactive screening labs from my PCP despite not really having symptoms.
My eGFR was 101 in 2024, then 74 in 2025 and 2026. Around that same timeframe I started supplementing creatine regularly, and my serum creatinine increased from 1.01 to 1.34. I lift weights consistently and have above average muscle mass.
I only had one urinalysis done. It showed trace protein only, with no blood, glucose, casts, or other abnormalities. The sample was first morning urine, I had not had any water yet, and I also take Desmopressin for nocturnal enuresis, so my urine was probably pretty concentrated.
Does this sound more consistent with creatine supplementation/concentrated urine affecting labs, or should I genuinely be concerned about early Chronic Kidney Disease? Curious if anyone has had similar experiences.
