Sodium
Bladder and kidney healthSodium is the primary electrolyte in blood that regulates fluid balance, nerve impulse transmission, and muscle contraction.
Imbalances can cause neurological symptoms, fluid retention, or dehydration.
Why this matters
Sodium levels reveal how well your body maintains fluid balance and supports nerve and muscle function. Low sodium can cause fatigue, confusion, or muscle cramps, while high sodium may indicate dehydration or kidney issues. Maintaining adequate hydration, a balanced diet, and kidney health helps keep sodium levels within a healthy range and supports overall cellular and cardiovascular function.
How this connects to other biomarkers
- Low Sodium (hyponatremia) with concentrated urine often suggests SIADH (the body holding too much water due to excess antidiuretic hormone). With elevated Fasting Glucose, the sodium reading may be falsely low (pseudohyponatremia from sugar-driven fluid shifts).
- High Sodium (hypernatremia) typically reflects water deficit (dehydration, inadequate intake) and must be corrected slowly to avoid brain damage from rapid shifts.
- Interpret Sodium alongside Potassium, Chloride, and Bicarbonate to assess overall fluid and acid-base status.
