Why is it important to keep to my fluid allowance?
One of the functions of healthy kidneys is to remove excess fluid from the body as urine. When your kidneys are not working properly (for some people with chronic kidney disease or for those who are on dialysis), not enough urine is made and fluid can build up in your body. This is often referred to as fluid overload, fluid retention or fluid weight gain. Not everyone with chronic kidney disease will have to restrict fluid intake, if you have fluid overload your doctor will advise you to keep to a fluid allowance.
What are the symptoms of fluid overload?
You may notice:
- Swelling in the hands, lower legs and feet
- Difficulty breathing and shortness of breath
- Changes in blood pressure
- Over time the excess fluid can weaken your heart
- Try not to have a drink with meals
- Take medication with food instead of water or other beverages
- Avoid or limit spicy foods
- Spread fluid intake throughout the day
- Snack on frozen grapes or cold fruits/vegetables to help quench thirst
- Make ice cubes out of your favourite drink
- Use smaller cups or measuring cups when drinking
- Use mouthwash, sugar-free mints, gum, sour candy or lemon/lime wedges to quench your thirst
- Freeze your drink bottle, this melts slowly and helps you drink slowly
*If you are prescribed a supplement drink (such as Nepro, Renilon or Ensure) – prioritise this within your fluid allowance for the day

- Know when you are actually thirsty and when you are not
