My son is 19 and has gone for 2 blood tests where they noticed his levels of creatinine were high.  This last time he said it was 150.  They are doing 1 more blood test then are going to do an ultrasound on his kidneys.  My son is convinced his levels are high because he works out and lifts weights up to 5 times a week for approx. 3/4 hour.  What do you think?  He hasnt taken any supplements for over 6 months but went to the doctor because he was very tired and sometimes nauseas and lightheaded.  He is a university student.
HelloThanks for your query, based on the facts that you have posted it appears that your son has raised Serum Creatinine levels. Creatinine is end product of protein metabolism which is excreted in urine. The raised creatinine level suggest diminished kidney function which may be due to 1) Renal Parenchymal disease 2) Infection of the kidney 3) Stones in the kidney It needs to be investigated further by doing following tests.1) Routine urine test and culture2) Ultrasound scanning of abdomen 3)Blood tests to assess Renal Function Please consult qualified Nephrologist for clinical evaluation and further treatment. Please note that this is definitely not due to weight Lifting Exercises that he is doing regularly. Chat Doctor.
