Hemodialysis is one kind of dialysis. It uses a machine that holds a filter called a dialyzer. As blood flows through the dialyzer, waste is removed and fluid and chemicals are balanced. Hemodialysis treatments are usually done at a special dialysis center. In some cases, treatments may be done at home.
How Hemodialysis Is Done
Problems to Watch For
Call your nurse or dialysis technician if you have any of these symptoms during or after treatment:
Hemodialysis usually takes about 3-5 hours. It is usually done 3 times a week.
You’ll have a regular schedule for your hemodialysis. Many centers have evening and weekend hours as well as weekday hours to help you continue working.
A trained nurse or technician connects you to the dialysis machine. He or she watches for problems and makes sure you are comfortable.
During treatment, only a small amount of blood (about 1 cup) is out of your body at any one time.
During or after your first few treatments, you may have a headache, muscle cramps, or feel nauseated. These should decrease as your body gets used to the treatments.
