Hemodialysis

Hemodialysis is a treatment that helps do the work of your kidneys when they are not functioning well. Your kidneys usually filter waste and extra fluids from your blood. In hemodialysis, your blood is gently removed from your body and passed through a special machine called a dialyzer, often called an "artificial kidney." This machine has a filter that removes waste products, excess salts, and extra water from your blood. The clean blood is then safely returned to your body. Hemodialysis is usually done several times a week and each session lasts about four hours. It is a lifesaving treatment for many people with kidney failure and can greatly improve your quality of life.

A newer therapy, called hemodiafiltration (HDF), combines the processes of both hemodialysis and hemofiltration. Like regular dialysis, it cleans your blood, but HDF also removes more waste products and larger molecules more effectively. This is achieved by using a larger volume of fluid for cleaning, which can lead to even better removal of toxins than standard hemodialysis. Some studies suggest that HDF may offer additional health benefits, such as improved heart health and better overall survival rates. Your nephrologist can help you decide the best therapy for your needs.
