How can sodium affect people with kidney disease?

When your kidneys are not healthy, extra fluid builds up in your body. This can cause swollen ankles, puffiness, a rise in blood pressure, shortness of breath, and fluid around your heart and lungs.

Sodium is a mineral found in foods and is the major part of table salt. Some sodium is needed for body water balance. But when your kidneys lose the ability to control sodium, you may experience the following:

  • fluid gain
  • high blood pressure
  • discomfort during dialysis
