Hemodialysis uses a machine to clean your blood. The dialysis machine has a filter called a hemodialyzer or dialyzer. The dialyzer works like an artificial kidney and removes the wastes and the extra fluid that builds up when your kidneys are not working. Hemodialysis can’t do all the work your kidneys did. Healthy kidneys work all day,everyday. Hemodialysis usually occurs three times a week for about four hours each time. Your time is based on your needs. Your kidney doctor (Nephrologist) orders the length of your treatment in order to help meet your body’s needs.
