Ultrafiltration is how dialysis removes the fluid you have gained between sessions, and the rate matters as much as the total.
What to know
- The target is set from your weight gain since the last session and your prescribed dry weight.
- Removing fluid too quickly causes cramps, low blood pressure and long recovery times.
- Large interdialytic weight gains force higher removal rates — controlling fluid intake between sessions directly improves how sessions feel.
- Dry weight is not fixed. Tell your nephrologist if you are consistently cramping or consistently oedematous.
