Should I stop exercising now due to high creatinine

[Tommy Wall]

I finally started working out a month ago I´m feeling really please by the result. Have a PT who pushes me along and I must say that only after a month of gym work I have increased both muscles and endurance.
However now I´m afraid to continue since my creatinine lab came back at 525 U/L which should be under 171.

My GP believes that it has to do with my hard workouts. I´m a bit afraid that in the long run maybe it will affect my Kidneys.

Will the Creatinine levels drop after that my body gets more used to my trainings or ?

Glad fof some input on this pls!

I never test CMP (Creatinine) without being at least 72hrs off from the weight room and having not used Creatine. Also you should never do Creatinine if you've eaten, that test should always be done fasted or it will come back high and your Dr will freak out over your Kidneys. If you're weight training or doing any hard exercise it will (probably) influence that test. Oh, Also influencing that test will be the increased muscle mass that you have, as well as a high protein diet. The test won't account for those things.
My strategy is gym M-F, and I test on a Monday. My Creatinine always comes back under the lab range, it's elevated, but under lab range.

That's the reason I stopped using creatine because the essay does not separate creatine levels and creatinine levels. Creatine will give you a false High reading.

However I don´t use Creatine and still I got that level.

Do you know what your level was before you started working out?

In Jan my C.K was 169 U/L

Men with more muscle mass, men who are dehydrated and those taking creatine may experience clinically non-significant increases in creatinine (eGFR). eGFR under 70 points at some sort of problem.

Calculate eGFR here

If you want to make sure if you indeed have a kidney issue, this is the most accurate test:

Thx Nelson! are you refering to Creatine (IDMS) or Creatina cinase (C.K) the first one I have 0,89 mg/dL and the latter 525 U/L. I don´t even know what the first test is for.
