Hemodialysis is a process of purifying the blood of a person whose kidneys are not working normally. It is a treatment to filter wastes and water from your blood, as your kidneys did when they were healthy.
How does hemodialysis help you?
- helps control blood pressure
- balance important minerals, such as potassium, sodium, and calcium, in your blood.
It can help you feel better and live longer, but it’s not a cure for kidney failure.
How the machine works
Did you know?
During hemodialysis, your blood is pumped through soft tubes to a dialysis machine where it goes through a special filter called a dialyzer (also called an artificial kidney). With hemodialysis, the filtering membrane is called a dialyzer and is inside a dialysis machine. Your blood is circulated through the dialysis machine and cleaned before being returned to your body.
