Electrolyte imbalances, particularly low calcium or high phosphorus, can trigger painful muscle cramps, especially at night.

Toxin buildup can cause restless legs or insomnia.

Poor sleep can also worsen fatigue and mood issues.

Kidneys help regulate blood pressure by controlling fluid and hormone balance.

Hypertension can both cause and result from kidney damage.

Important:
Kidney disease often develops silently, and many of these symptoms appear only in advanced stages. Early detection through blood tests (creatinine, eGFR) and urine tests is crucial.
Tip: If you notice 2–3 of these signs together, it’s worth getting a kidney checkup—even if you feel otherwise healthy.
