Rise in Creatinine

Creatinine is a waste product of the muscles. In a healthy body, the kidneys filter creatinine from the blood and excrete it through the urine. High levels of creatinine can indicate kidney issues.

Creatinine is a byproduct of normal muscle function. It is a metabolite of creatine phosphate, which the muscles use as an energy source.

The greater someone’s muscle mass, the higherTrusted Source their creatinine levels. For this reason, males tend to have higher creatinine levels than females.

The primary way in which the body removes creatinine from the blood is by filtration through the kidneys and then excretion in the urine.
