Creatinine level is clinically important because it is a measurement of renal function. Therefore, once the creatinine level increases, many people will worry that if they have kidney damage. In fact, besides kidney damages, there are several other causes of high creatinine level. The following article will explain the causes of high creatinine level one by one.
1. Kidney damage
In normal cases, after the creatine in muscle converts to creatinine, they
will go into kidneys through blood circulation. At last, the creatinine will end
up in urine and then be discharged out of body so it can keep a consent level in
our bodies. However, once kidneys are damaged, they can not clear the creatinine
in the body so the creatinine level will increase. In fact, creatinine level is
not a very sensitive index in assessing renal function. Only when glomerular
filtration rate ( GFR) declines to 1/3 of the normal level, will the creatinine
level increase obviously.
2. Intense exercise
Intense exercise can place stress on muscle cells, which can cause creatine
in muscle release into the blood stream, which can cause creatinine level to
increase transiently. This is a normal physiological phenomenon. If you can
adjust your exercise intensity, the creatinine level will recover normal after a
3. Muscle trauma
When receiving muscle trauma, creatinie that is usually found within muscles
may enter the blood stream because of this damage. Therefore, the creatinine
level will increase.
The patients can get much extrinsic creatinine from the meat they eat, which
also can cause the creatinine level to increase.
The above article has introduced the main causes of high creatinine level.
Therefore, if your creainine level is higher than the normal level, you should
make clear its specific cause and then adopt relative measures accordingly.
