Dialysis is a treatment that can take over the job of your kidneys. It is done during regular visits to a clinic. Your blood passes from your body to a machine. The machine will clean the blood then return it to your body. You may be on dialysis for a short time, or you may need it for the rest of your life.
There are two types of dialysis. This fact sheet will focus on hemodialysis.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- A drop in blood pressure during hemodialysis
- Problems with heart rhythm
- Muscle cramps
- Nausea, vomiting
- Feeling hot, sweaty, weak, and/or lightheaded
- Disruption of calcium and phosphorus balance, resulting in weakened bones
If you have heart problems, this may increase your risk of complications from hemodialysis.
