Minerals

Sodium

Sodium regulates fluid balance, blood pressure, and muscle function. Proper levels are key for sustained energy and physical performance.

What It Measures

This test measures the concentration of sodium in your blood. It helps assess hydration status, kidney function, and electrolyte balance.

Why It Matters

Sodium balance is essential for proper nerve transmission, muscle contraction, and blood pressure regulation. Significant imbalances can affect brain function and require medical attention. Consult your healthcare provider for guidance.

When to Test

Testing is commonly included in routine blood panels. It may also be recommended if you take diuretics, experience confusion, have kidney disease, or show signs of dehydration or overhydration.

Symptoms

Low Levels

Low sodium (hyponatraemia) may cause headache, nausea, confusion, fatigue, muscle cramps, and in severe cases, seizures. It requires prompt medical evaluation.

High Levels

High sodium (hypernatraemia) may cause excessive thirst, restlessness, confusion, and in severe cases, neurological symptoms. It is often related to dehydration.

Lifestyle Tips

Maintain balanced salt intake and stay well-hydrated. Excessive salt consumption may contribute to high blood pressure. Be mindful of sodium content in processed foods.

Frequently Asked Questions

How much sodium should I consume daily?
Most guidelines recommend limiting sodium intake. However, individual needs vary based on health conditions and activity level. Your healthcare provider can offer personalised guidance.
Can drinking too much water lower sodium?
Yes, excessive water intake without electrolyte replacement can dilute blood sodium levels (hyponatraemia), especially during prolonged exercise.
Is all salt bad for health?
Sodium is essential for health — the concern is excessive intake. A moderate, balanced approach to salt consumption is generally recommended. Discuss your needs with your healthcare provider.
