Overview
Aerobic activity improves blood pressure, cardiovascular risk and mood, all of which matter more in kidney disease than the calories burned. Combined with weight loss, it frequently reduces the need for antihypertensive medicine.
Why it's done and who it helps
Everyone able to walk, including people on dialysis and after transplantation.
A realistic target
- Build towards 150 minutes a week of moderate activity, in bouts as short as ten minutes.
- Moderate means you can talk but not sing.
- Add two resistance sessions a week; cardio alone does not protect muscle.
Blood pressure and medication
Weight loss plus exercise can lower blood pressure substantially. Dizziness on standing is a common sign that your medicines now need reducing - report it rather than stopping exercise. Never stop antihypertensives yourself.
Safety
Stop and seek advice for chest pain, unusual breathlessness, palpitations or fainting. On dialysis days, expect lower capacity after treatment.
Preparing for your appointment
Can I exercise with anaemia?
Often yes, at lower intensity, but persistent breathlessness needs investigation.
Does exercise slow CKD progression?
It improves cardiovascular risk and function; the effect on progression is indirect but worthwhile.
When to contact your care team
Contact the clinic promptly if you have any of the following:
- Vomiting or diarrhoea lasting more than 24 hours, or you cannot keep fluids down
- Passing much less urine than usual, or new swelling of the legs or face
- Severe pain in the upper abdomen that spreads through to your back
- A weight change of more than 2 kg in a week that is not explained by fluid
- A missed weekly weight, a missed dose, or any hospital admission
If you are seriously unwell, contact NHS 111 or your renal unit directly rather than waiting for your next review.
