Swelling (Edema) in Kidney Disease
Why kidney disease causes swelling in the legs and face, and how it is managed.
Last updated: 24/9/2026
When kidneys fail, extra salt and fluid build up, causing swelling (edema) — most often in the feet, ankles and around the eyes.
Why it happens
Damaged kidneys cannot remove enough sodium and water, so fluid leaks into tissues, especially in the lower body.
Management
- ✓Limit salt and fluid as advised
- ✓Take diuretics if prescribed
- ✓Report rapid weight gain to your doctor
Frequently Asked Questions
