FLUID RESTRICTION

 

Healthy kidneys regulate fluid balance and help to remove fluid and waste from your body. When you have kidney failure, hemodialysis gets rid of excess fluid and waste products in the body but not as effective as healthy kidney. Weight gain between dialysis is due to excess fluid builds up between dialysis treatments.

Extra fluid with excess weight gain can affect your body in harmful ways. It can cause:

  • Swelling in the feet, ankles, wrists, face
  • Shortness of breath due to fluid in the lungs
  • Increase in blood pressure
  • Heart problems, e.g. fast pulse, weakened heart muscles and an enlarged heart
