What are the main treatments for kidney failure?

The main treatments for kidney failure are dialysis and kidney transplants.

How does kidney dialysis work?

Kidney dialysis acts as an artificial kidney by removing toxins and excess substances from the blood. Unfiltered blood is taken from the body, filtered through a machine with dialysis fluid, and then returned to the body.

What is the composition of dialysis fluid and why is it important?

Dialysis fluid contains glucose and salts at normal blood levels but no urea. This creates concentration gradients that allow urea and other toxins to diffuse out of the blood, while necessary substances are maintained.

What are the advantages of dialysis?

Dialysis removes waste and excess fluids, providing immediate relief from kidney failure symptoms. It can be done at home or while travelling, and it serves as a temporary or long-term treatment.

What are the disadvantages of dialysis?

Dialysis requires a significant time commitment, with multiple sessions per week. It also involves strict dietary restrictions and can reduce quality of life, impacting daily activities and causing emotional distress.

What is a potential risk of a kidney transplant?

The patient’s immune system may reject the donated kidney.
