Kidneys are the vital human organs and play an indispensable function of filtration and purification of blood. When, the kidneys are not working properly due to a disease or an injury, your body is not able to flush harmful toxins out of the body. Therefore, a dialysis is used to perform the function of the kidneys.

Dialysis is a procedure in which a machine is used to filter and purify the blood. Dialysis performs all the function of the kidneys such as control blood pressure, removing waste, maintaining the level of sodium, salt, and potassium in the blood. However, dialysis is not a long-term solution for kidney disease, if the kidney is damaged a kidney transplant has to be done.

There are two types of Dialysis: Hemodialysis, Peritoneal Dialysis

Hemodialysis- Hemodialysis procedure involves the use of an artificial kidney called ‘hemodialyzer’. Hemodialysis is carried out three times in a week and generally takes three to five hours to remove all the chemicals and waste from the patient’s body. An incision is made to create an entry point into your blood vessels so that the blood can flow properly through the artificial kidney. Patient’s of hemodialysis are restricted to the limited amount of fluids and have to avoid particular foods.

Peritoneal Dialysis- In peritoneal dialysis, a surgery is done to insert a thin and flexible tube (catheter) around your abdomen area. A fluid known as dialysate flows from this tube and drains out the harmful toxins and other waste from your blood. The Peritoneal dialysis procedure is to be, carried daily. Peritoneal dialysis is less complicated than hemodialysis, but there is a risk of infection due to the catheter.

Preparing for Dialysis

  • Before undergoing dialysis for the first time, a minor surgery is carried out to insert a catheter or implant a device to create an access to your blood vessels.
  • Wear comfortable clothes during your dialysis treatment.
  • Do not lift any heavy weights.
  • Avoid excessive intake of fluids.
  • Do not put too much pressure on your abdomen area.
  • Always follow instructions as stated by a nephrologist.


Besides the benefit of these life saving treatments, there is also some risk associated with both hemodialysis and peritoneal dialysis.

My kidneys had stopped working and I have to go through dialysis on a regular basis. This is a very useful process for the kidney patients.
