Reviewing patients blood work is something I do in the clinic daily. The creatinine level is something that goes from 1.4. to 1.5, to 1.6 to 2.0 and dialysis pretty quickly. These are the numbers my patients have before needing to be hooked to a machine 3 x a week for hours at a time. Your body is telling you to stop.
People on this site will tell you don't worry it's your training, your an athlete, or dehydration. This minimizes the issue and is denial. Repeatedly high creatinine is a huge warning sign. A study of elite, I repeat ELITE athletes showed they had a slightly higher creatinine level, but none of them were even over 1.33.
Diabetics and elderly with high blood pressure have always been the most common dialysis patients. Nowadays, anabolic steroid abusers are the fastest growing group of young people needing dialysis. The nephrologists I work with are the top in the field and all see the link between the hugh spike in drug use with the trend. It's not worth it for another inch on your bicep. The former abusers I see 3 x a week wish they never touched gear.
This is absolutely ridiculous. You always go from one extreme of “don’t worry” to dialysis talk.
Your remarks are way off base reading a one time post/bloodwork from the OP. How about a middle ground of investigate further?
I’ve had creatinine of 1.5-1.6 since I was 20 (I’m 35) You know what’s wrong with my kidneys? Nothing.
Cystatin C a constant 0.62
24 hour urine screen 100% perfect
Ultrasound perfect
Every spot urine screen also all good
Stable creatinine for 15 + years
I am Uber paranoid about health so I pay OOP each year to get these tests done because I have no medical necessity to get them done (so insurance won’t pay).
I waited to respond to your post as I had a nephrologist appt today (paid $500 OOP for him to go through my labs...all look perfect).
His response was this....
“You have to look at the entire clinical picture. Any well muscled person with perfect blood work but elevated creatinine is likely ok and you can verify that with a few extra tests. I see large men all time time with creatinine over 1.4 yet rarely over 1.7 and what I look most for is the trend over time. If the patient has an elevated creatinine with other markers off like bun, lipids, liver values, electrolytes my level of concern rises but, again, we can easily get it figured out with additional testing”.
My doc loves cystatin c. 24 hr urine is a pain but awesome. A little nugget is my nephrologist always orders c reactive protein as he said there is growing evidence that may be a secondary indicator of impending kidney issues.
My qualifications? Majored in biology, sold dialysis equipment (worked on the clinical side so had to understand all this stuff) and have been going to a neurologist for 15 years.
I will say this...my doctor told me if you pulled the general population of his patients and did creatinine on 100 of them it may somewhat align with what you are saying because they’d likely be people with actual kidney issues, other health issues, and not have a reason for higher levels like muscle mass and as mentioned they’d have other markers that are off.
Your posts are way off base and alarmist and that’s coming from a guy who has easily spent $15,000 OOP on kidney tests I don’t need because I’m paranoid.
