Nutrition & Dietetics Kidney Failure (Renal)

Diet plays an important part in the treatment of kidney failure.  

Waste products can build up in the blood as kidney function worsens. It may be necessary to make changes to the diet to help control the build up of waste products and the symptoms they cause.


  • Tiredness
  • Altered taste
  • Reduced appetite
  • Nausea 
  • Shortness of breath

The dietitian will see patients at their kidney clinic appointment at Southmead Hospital Bristol and advise on altering the diet (if needed).

Information is tailored to the needs of each patient taking into consideration their:

  • Blood results
  • Kidney function
  • Treatment
  • Food preferences. 

The dietitian can provide information and ongoing support to patients on:

  • Eating a balanced, healthy diet
  • Staying well nourished if there is decline in appetite
  • Limiting salt intake to help blood pressure control
  • Reducing the intake of minerals such as potassium and phosphate in the diet if blood levels are raised
  • Other diet related questions

Advice may alter as the kidney function changes or following a kidney transplant. Diet should only be altered if advised by the dietitian or doctor.
