The main goal of dialysis treatment is to maintain life and improve quality of life. Dialysis serves as an essential intervention for patients with kidney failure, where the kidneys are unable to effectively filter waste products and excess fluids from the blood. By performing these functions artificially, dialysis helps to stabilize the patient’s medical condition, prevent the accumulation of harmful substances in the body, and alleviate symptoms associated with kidney failure, such as fatigue, swelling, and electrolyte imbalances.

While some treatments aim to cure kidney disease or restore kidney function, dialysis is a supportive treatment rather than a curative one. It allows patients to manage their condition and continue their daily activities, significantly enhancing their quality of life. Consequently, maintaining life — by preventing potentially fatal complications of kidney failure — and improving the overall quality of life are primary objectives of undergoing dialysis.
