Dialysis - Purpose, Procedure, Cost And Side Effects

About Types Procedure Signs Side effects Recovery Cost Results Alternatives Diet

What is dialysis?

Dialysis performs the function of kidneys until they are functional. It is performed when the kidneys cannot function properly, a person needs to undergo to keep their body in balance. The process of dialysis removes waste, salt as well as the extra water, thus preventing them from accumulating in your body. It also ensures to keep certain chemicals in the blood like sodium, bicarbonate, and potassium within optimal levels. Lastly, it also helps in controlling blood pressure.

A healthy kidney has the function of filtering around 1500 liters of blood every day. If the kidneys fail to work properly, waste can accumulate in the blood. This can lead to serious health issues, resulting in coma and even death.

What are the different types of dialysis?

There are two different types of dialysis:

  • Hemodialysis: A hemodialyzer is used for removing the waste and extra chemicals from the blood.
  • Peritoneal dialysis: It involves a surgery where a catheter is implanted in the stomach area, and a fluid named dialysate flows into the abdomen. This fluid draws out the waste from your abdomen after which it is drained out.

How does dialysis work?

Dialysis can be done in the dialysis unit of the hospital or at your home. The doctor decides on the location based on your preferences and the status of your condition.


This is the most common form of dialysis. The doctor creates an incision so that the blood can flow to the artificial kidney or the hemodialyzer. The entrance point is made by creating a small incision in the arm or the leg. It can also be done by joining one of the arteries to a vein under the skin in order to make a bigger blood vessel known as a fistula.

This surgical entrance point allows a large amount of blood to flow from your body during the treatment. As a result, more blood is purified and filtered. This treatment usually lasts for three to five hours. A patient is generally required to undergo a hemodialysis thrice every week. This option generally works for people who require long-term treatment.

Peritoneal dialysis

This treatment involves implantation of a catheter in the area around the belly through which the fluid is administered to your body. The dialysate fluid draws out the waste from the blood, and then the waste is drained from your abdomen.

Peritoneal dialysis can be further classified into two types. One is the Continuous Ambulatory Peritoneal Dialysis, where the abdomen is filled and drained multiple times in a day. The other is the Continuous Cycler-Assisted Peritoneal Dialysis, where a machine is used for cycling the fluid in and out of the abdomen. It is generally done at night when the patient is sleeping.

What are the signs that you need dialysis?

When the kidney stops working and the stage of kidney failure develops and you lose about 85-90 percent of your kidney then the situation comes that you need dialysis.
