Dialysis Basics > Understanding Fluid
Too much fluid can negatively affect your health.
Why is limiting fluids so important:
- The kidneys are no longer able to get rid of excess fluid
- Those who gain a lot of fluid between dialysis treatments have more discomfort during treatments
- Large fluid gains cause heart and lung problems
What can happen if I gain too much fluid between treatments:
- Difficulty breathing
- Swelling in hands, feet, face
- High blood pressure
- Headache
- Cramps
- Low blood pressure, cramps, nausea and vomiting and dizziness during dialysis
- Damaged heart
- Feeling tired or "washed out"
What can I do to limit fluid gain between treatments:
- Don't eat salty foods
- Use small cups or glasses and measure fluids
- Know what counts as a fluid (anything that turns liquid at room temperature)
- Use hard candy or chewing gum to stop feeling thirsty
- Brush teeth or use mouthwash to stop thirst
- Use lemon wedges to stimulate saliva
- Take pills with pudding or apple sauces instead of water
Ask your dietitian or Care Partner for other hints on limiting your fluid intake.
