What is the main purpose of dialysis treatment?

The main purpose of dialysis treatment is to replace kidney function. In patients with renal failure, the kidneys are unable to adequately filter waste products, excess fluids, and electrolytes from the blood. Dialysis serves as an artificial substitute for this critical function. It helps maintain necessary balances in the body by removing toxins and excess fluid, effectively performing the work the kidneys would normally do.

In contrast to curing renal failure, dialysis is not a treatment that restores kidney function but rather a life-sustaining procedure that takes over some of the duties of the kidneys. While dialysis can have secondary effects on blood pressure regulation, that is not its primary purpose. Enhancing liver function is irrelevant to dialysis, as it specifically addresses kidney function and related deficiencies.
