Hemodialysis is a treatment that filters wastes, salts, and excess fluid from the blood when the kidneys are no longer able to do so effectively. It is the most common form of dialysis and is often used in patients with chronic kidney disease (CKD) or kidney failure. Hemodialysis helps improve the quality of life and manage symptoms while patients await a kidney transplant or as long-term therapy.
Hemodialysis is a process where blood is passed through a machine called a dialyzer (artificial kidney) to remove toxins and extra fluid. The cleaned blood is then returned to the body.
Each session usually lasts 3–5 hours and is performed several times a week.
Hemodialysis is recommended for patients with:
Most patients require hemodialysis 3 times per week, with each session lasting 3–5 hours. The schedule may vary depending on kidney function, overall health, and medical advice.
The treatment itself is not painful, but patients may feel a brief sting when needles are inserted into the access site. During or after dialysis, some patients may experience fatigue, low blood pressure, cramps, or headaches, but these can often be managed.
While generally safe, potential risks include:
These risks are monitored closely by dialysis care teams.
No. Hemodialysis does not cure kidney disease — it only replaces some of the lost kidney function. Kidney transplant is the only permanent treatment, but dialysis can sustain life and well-being until then.
Many patients live for years on dialysis with a good quality of life. Life expectancy depends on age, other medical conditions, and treatment adherence. Patients who also follow medical advice and consider a kidney transplant often do better long-term.
