summary

In recent two days, I always feel very uncomfortable. I thought it was caused by overwork recently, but I didn't get better after a few days' rest. So I went to the hospital to have an examination. The doctor said it was high creatinine. Today, I'd like to talk about high creatinine.

What is high creatinine

First: the creatinine value is higher than the normal value is called high creatinine, creatinine includes blood creatinine and urine creatinine, but blood creatinine is more meaningful to measure renal function. So high creatinine generally refers to high blood creatinine. Generally speaking, the normal value of serum creatinine is 44-106 μ mol / L, but according to the new international standard, it is 59-106 μ mol / L. when the serum creatinine exceeds 106 μ mol / L, it means that the kidney may be damaged, and renal insufficiency and renal failure have occurred.

Second, the stage of inflammatory injury was above 106 μ mol / L, the stage of renal function injury was 186 μ mol / L, and the stage of renal failure was 451 μ mol / L. Creatinine in the body is mainly produced by muscles and excreted through the kidneys. In general, the amount of creatinine production is constant, and the level of serum creatinine mainly depends on the amount of creatinine excreted by the kidney.

Third: the compensatory function of the kidney is very powerful. If both kidneys are normal, as long as one kidney functions, serum creatinine can be maintained at a normal level. That is to say, the renal function must be reduced to half of the normal level before it can cause the increase of serum creatinine. Therefore, serum creatinine can not fully reflect the early and mild decline of renal function.

matters needing attention

High creatinine has many problems that need attention. For example, in terms of diet, it's better to eat less spicy food and more green fruits and vegetables. At the same time, patients should often go to the hospital for reexamination. Only in this way can patients get rid of this disease and finally recover.
