Fluid accumulation in body tissues — usually feet, ankles, or around the eyes — the visible sign of fluid retention in kidney disease.
Edema in CKD reflects sodium and fluid retention: failing kidneys excrete less sodium and water. It worsens with heart failure and protein loss. Management: sodium restriction, fluid limits (especially in dialysis), diuretics, and treating the underlying cause. In dialysis, edema correlates with interdialytic weight gain.
Excess extracellular fluid volume in kidney patients from inadequate excretion, causing edema, hypertension, pulmonary congestion, and increased cardiovascular risk.
Sodium from salt and processed foods — the main driver of fluid retention and blood pressure in kidney disease.
A diuretic (furosemide, torsemide, bumetanide) that removes fluid in CKD and dialysis patients by blocking sodium reabsorption.
The weight gained between dialysis sessions from fluid and salt intake - kept below ~3% of dry weight to protect the heart.
