Why Does Weakness Occur in Kidney Disease

Weakness in kidney disease occurs because damaged kidneys cannot properly filter waste or maintain essential body functions. Reduced production of erythropoietin leads to anemia, lowering oxygen supply and causing fatigue. The buildup of toxins in the blood makes the body feel tired and sluggish. Electrolyte imbalances and protein loss also affect muscle strength. Additionally, poor appetite, sleep problems, and fluid imbalance further contribute to low energy levels and overall physical weakness.
