Kidney disease dietitian

Eating for kidney health depends on your stage of kidney disease and your blood results. Our dietitians build an individual plan with your GP and care team.

Understanding the condition

Chronic kidney disease (CKD) means the kidneys have been damaged or have not worked as well as they should for more than three months, so waste and fluid build up in the body.1 About one in seven Australian adults has signs of it, and most do not know.5 Diabetes and high blood pressure are the most common causes, and early stages usually cause no symptoms, so it is found through blood and urine tests. Care focuses on slowing progression by looking after blood pressure, blood glucose and cholesterol, with food as one important part.1

There is no single kidney diet. What is right for you depends on your stage of kidney disease, your blood results, your medicines and other conditions, so advice from an Accredited Practising Dietitian is recommended.2,3 Cutting back on salt is usually advised, and protein needs are individual.2,4 Not everyone needs to limit potassium, and phosphate advice is individual, especially for people on dialysis. Any change is guided by your blood results and set with your doctor or kidney team.2,3

What to look out for, and how we help

Symptoms are a guide, not a diagnosis. Your GP confirms the diagnosis; our team helps you manage it day to day.

What you might notice

  • Early kidney disease usually has no symptoms and is found through blood and urine tests
  • Tiredness, nausea or loss of appetite
  • Needing to pass urine more often at night, or frothy urine
  • Swollen ankles, itchy skin or restless legs
  • Higher risk if you are living with diabetes or high blood pressure, so regular kidney checks matter
  • Red flag: see your doctor promptly if you notice blood in your urine, swelling, shortness of breath or new nausea and tiredness, and call 000 if you need urgent medical help. Do not start limiting potassium or phosphate, or take supplements, without medical advice.

How our team helps

  • Assessment of what you eat, your kidney stage, your blood results, your medicines and your medical history
  • A personalised eating plan that fits your stage, covering salt, protein, potassium and phosphate only where your results and doctor say it is needed
  • Label reading and shopping skills, including finding hidden salt in packaged foods
  • Cooking demonstrations and practical meal ideas that suit your tastes and budget
  • Support for people living with diabetes or high blood pressure alongside kidney disease
  • Referral to a specialist renal dietitian if you are on dialysis or have advanced kidney disease, and coordination with your GP, kidney team, pharmacist and exercise physiologist

Common questions

Do I have to cut back on potassium with kidney disease?
+

Not always. Many people with early kidney disease do not need to limit potassium, and restriction is only advised when blood results call for it, such as in later stages or on dialysis. Please check with your doctor before cutting out fruit, vegetables or other foods.

Is there a special kidney diet?
+

No single diet suits everyone. Your needs depend on your stage of kidney disease, your blood results, your medicines and other conditions such as diabetes. A dietitian with kidney experience tailors the advice to you and updates it as things change.

Should I eat less protein?
+

Not necessarily. Protein needs are individual and depend on your stage and overall health, and eating too little can cause its own problems. Please do not change your protein intake without advice from your doctor or a dietitian.

Can diet slow kidney disease?
+

Diet is one part of care, alongside managing blood pressure and blood glucose and taking prescribed medicines. Eating well supports your kidneys and general health, but it does not replace medical treatment or regular kidney checks.

Can you help if I am on dialysis?
+

Dialysis and advanced kidney disease need a specialist renal dietitian, usually through your kidney unit. We can support the everyday side of eating well and work alongside that team, and we will tell you plainly if your needs sit outside what we do.

Not sure where to start?

Tell us what is going on and we will point you to the right discipline, or to more than one. Most people start with a single appointment and leave with a plan the rest of the team can see.
