What happens to my blood while it’s in the filter?

Blood enters at one end of the filter and is forced into many, very thin, hollow fibers. As your blood passes through the hollow fibers, dialysis solution passes in the opposite direction on the outside of the fibers. Waste products from your blood move into the dialysis solution. Filtered blood remains in the hollow fibers and returns to your body.

In the filter, your blood flows inside hollow fibers that filter out wastes and extra salt and water.

Your nephrologist—a doctor who specializes in kidney problems—will prescribe a dialysis solution to meet your needs. The dialysis solution contains water and chemicals that are added to safely remove wastes, extra salt, and fluid from your blood. Your doctor can adjust the balance of chemicals in the solution if

  • your blood tests show your blood has too much or too little of certain minerals, such as potassium or calcium
  • you have problems such as low blood pressure or muscle cramps during dialysi

Can the dialyzer do everything my kidneys once did?

No. Hemodialysis can replace part, but not all, of your kidney function. Dialysis will help improve your energy level, and changes you make to your diet can help you feel better. Limiting how much water and other liquid you drink and take in through foods can help keep too much fluid from building up in your body between treatments. Medicines also help you maintain your health while on dialysis.
