What is the main goal of hemodialysis?

The primary goal of hemodialysis is to remove waste products and excess fluid from the bloodstream. This process is essential for individuals with kidney failure, as their kidneys can no longer effectively filter toxins and maintain fluid and electrolyte balance. Hemodialysis uses a machine that acts as an artificial kidney, allowing blood to be cleansed of waste products such as urea and creatinine, as well as excess electrolytes and fluid, which can accumulate in the body and lead to various complications if not properly managed. Achieving this balance helps to alleviate symptoms of kidney disease, prevent complications, and improve the overall quality of life for patients undergoing treatment.

Other options, while they may touch on aspects of patient health, do not align with the main therapeutic intent of hemodialysis. For instance, increasing fluid retention goes against the goals of dialysis, which aims to eliminate excess fluid. Boosting the immune system and enhancing red blood cell production are important health objectives, but they are not direct goals of the hemodialysis process itself.
