How Does Dialysis Help Kidney Failure

2013-04-21 15:28

It is widely known that dialysis will be required by kidney failure patients to sustain their life when illness condition deteriorates to a certain stage. However, many kidney disease sufferers have no ideal about how dialysis helps kidney failure.

How does dialysis help kidney failure?

Dialysis is a life-sustaining medical method and it helps kidney failure patients further their life by removing toxins in blood which are produced during metabolism and normally discharged through kidney. Since kidneys are responsible for removing these toxins, when kidney failure is caused, toxins can not be discharged in time and consequently, they build up in blood.

If kidney disease left uncontrolled, more and more toxins will pile up in blood. For people with kidney failure, content of toxins in blood has reached to a certain level and these toxins need to be removed as quickly as possible; otherwise, other internal organs will be damaged. In clinic, dialysis just play such a role to help kidney failure patients to remove toxins from the blood.

Dialysis is a medical procedure in which blood is induced out of patient’s body and then filtered by dialysis machine. Dialysis only helps to purify blood and can not improve kidney function, so once kidney failure patients start dialysis, they need to do dialysis repeatedly.

Side effects of dialysis for kidney failure patients

Dialysis is helpful, and it helps kidney failure patients protect their internal organs. However, even though dialysis has so many benefits, it is not an ideal and long-term solution, as long time dialysis will cause many side effects like low blood pressure, restless leg syndrome, muscle cramp, kidney infection, itchy skin, headache, anemia, nausea and electrolyte imbalance and so on.

Besides, after doing dialysis for some time, some kidney failure patients found their urine output decreases. Kidneys are in charge of producing urine and decreased urine output means healthy kidney tissues become lesser. Dialysis helps to filter blood outside patient’s body and under such a condition, less blood flow into kidney and less urine is produced. If this condition lasts for a long time, patient’s urine output will decrease gradually.

On one hand, dialysis helps kidney failure patients further their life, but on the another hand, it brings them lots of discomforts. Therefore, even though dialysis is helpful, many kidney failure patients are reluntant to start dialysis when their creatinine becomes very high.
