In dialysis, the functions of the kidney (which is the filtration of blood and removal of waste products & excess water) are performed through artificial treatment. The blood gets filtered multiple times through the two kidneys in our body. Small units called nephrons are what kidneys are made up of which are responsible for blood filtration. Filtration of the blood helps in the following critical functions:
- Maintenance of the critical water & electrolyte balance
- Maintaining the blood pressure
- Removal of waste products, chemicals, and excess water
The ability to filter the blood is lost by the nephrons in kidney diseases. People experience end-stage renal disease or kidney failure when the ability to filter the blood by the kidney reaches a critical level. This is done through the procedure of treatment called dialysis.
The two broad categories of dialysis treatments are:
- Peritoneal dialysis
