May 22, 2025 ET Online

Swelling (Edema)

Persistent swelling in your feet, ankles, or calves may indicate kidney trouble, as fluid accumulates when kidneys fail to properly filter and eliminate excess water from the body. Image Source: iStock

Muscle Cramps

Frequent muscle cramps in the legs may result from electrolyte imbalances like low calcium or potassium levels, often caused by declining kidney function and waste buildup in blood. Image Source: iStock

Restless Legs Syndrome (RLS)

Restless Legs Syndrome involves uncomfortable leg sensations with a strong urge to move, frequently occurring at night and linked to iron deficiency or uremia from kidney dysfunction. Image Source: iStock

Numbness or Tingling

Numbness, tingling, or pins-and-needles sensations in your legs could indicate nerve damage, a complication of chronic kidney disease and rising toxin levels in blood. Image Source: iStock

Skin Rash or Itching

Dry, itchy, or flaky leg skin may develop when the kidneys can’t effectively eliminate waste. This allows toxins to build up in the bloodstream and cause skin irritation or rashes. Image Source: iStock

Weakness or Fatigue in Legs

If your legs feel constantly weak or heavy, it could be due to anaemia from kidney disease, as damaged kidneys fail to produce enough red blood cell hormones. Image Source: iStock

Discolouration

A brownish or dark discolouration on the lower legs can signal waste buildup and mineral imbalances in advanced kidney disease, reflecting poor toxin elimination and blood circulation issues. Image Source: iStock

Joint Pain or Bone Pain in Legs

Aching knees or hips may stem from kidney-related mineral and bone disorders, where calcium and phosphate imbalances weaken bones, causing joint discomfort or persistent leg pain. Image Source: iStock
