Hemodialysis involves the use of an artificial kidney!
Hemodialysis uses an artificial kidney called a hemodialyzer to remove wastes, excess fluids and extra chemicals from the blood. Kidneys that are healthy and functioning correctly, clean our blood and remove extra fluids in the form of urine. They are also responsible for producing enzymes and hormones that keep our body healthy.
Your dialysis only replaces some of the functions that your kidneys can no longer perform. This is only required if your kidneys are damaged and can no longer remove enough wastes and fluids from your blood, in order for you to stay healthy. This is usually when the functions of your kidneys are below 15%.
How does hemodialysis work?
In this particular dialysis treatment, your blood is pumped through a dialysis machine which exposes it to a special filter.
This filter is made of a semi-permeable membrane that acts as an artificial kidney. This device is also known medically as a dialyzer. This is where your blood would be cleaned of its wastes products before it is pumped back into your body.
So how is the blood clean during hemodialysis?
There are two parts to the dialyzer machine. One area of the dialyzer is for your blood and the other area is for a cleansing solution called dialysate. These two areas are delicately separated by the thin membrane. Because of the size of the filtering capabilities of this thin membrane, your blood cells, its proteins, and other important things remain in your blood.
This is simply due to the fact that they are to large to pass through the membrane. Only the smaller wastes products such as urea, creatinine, potassium and excess fluids are allowed to pass through the membrane.

The right amount of treatment will also enable you to live a longer more healthier life.

When you begin this type of dialysis, the needles used may provide some discomfort at first.
This is usually when they are being placed in your fistula or graft. Over time you may get use to this process. Still as part of your dialysis treatment, your health care team will make sure that you are as comfortable as possible. Symptoms such as cramps, headaches, nausea, or dizziness are uncommon.
