Sodium & Fluids
Managing sodium and fluids is important for people on
dialysis. Too much sodium increases thirst and causes fluid buildup in the body,
which can hurt your heart.
Fluid buildup can also cause cramps during your dialysis
session, high blood pressure, and shortness of breath.
Sodium is found in many processed foods and is a major
part of table salt. Instead of using salt, use sodium-free spices and herbs. You
can also limit your salt intake by avoiding foods high in sodium, such as many processed
The primary role of sodium in the body is to maintain
normal fluid balance. Food usually contains more sodium than the body needs, and
too much can be harmful for people with chronic kidney disease. Sodium causes fluid
to build up in your body and leads to many problems like raising blood pressure,
swelling, and putting a strain on your heart and kidneys.
The amount of fluids you take in when you're on dialysis
can make a difference to your health. Consuming too much fluid can cause cramps
during dialysis, raise high blood pressure, and cause shortness of breath.
Dialysis helps remove those excess fluids, but fluids
can build up quickly in between dialysis treatments. So it's important to get just
the right amount of fluid so you can feel your best.
What counts as a fluid? Whatever you drink throughout
the day counts as fluids. But you may be surprised that all of the following count
as fluids too:
- Ice cream
Remember: for people on dialysis,
fluid counts as anything that turns to liquid at room temperature.
