How Does Dialysis Help Patients with Kidney Failure

What is Dialysis?
Dialysis is also called artificial kidneys, which, to some extent, can really replace kidneys to do a lot of work when people's kidneys cannot do their job well.
Normal kidneys have their functions to excrete helpful substances (prostaglandin and erythrogenin) so as to regulate blood pressure and provide enough blood to human body.
Kidneys can also remove waste and toxin from human body, so that people's inner environment can be kept clean.
Kidneys help maintain the proper levels of fluid in body so as to prevent dehydration or fluid retention.
Dialysis, as an artificial kidney, can partially replace kidneys to play its function to discharge toxin and remove extra water in body. It seems that dialysis treatment is the only effective method to keep the inner environment of body clean.
When do Patients with Kidney Failure Receive Dialysis?
In the early stage of Kidney Failure, patients are more likely to get a better recovery with the help of conservative treatment, such as some herbal medicines. In this condition, it is not necessary for patients to take dialysis.
If patients who are at the early stage of Kidney Failure didn't pay attention to their disease or get effective treatment, they are prone to the End-stage Kidney Failure. If so, patients have to receive dialysis to help them remove toxin from their body.
Note that one main index that can be used to judge whether patients should receive dialysis is the serum creatinine level. Generally, patients with the creatinine level of 450mg/ dL are recommended to receive dialysis. Whether patients will receive dialysis mainly depend upon their own disease condition and their local reference values of creatinine level.
