Sodium LIS Code: Na (ISE-I)

Importance of Electrolytes in Metabolic Function
Electrolytes play a vital role in nearly all major metabolic processes in the body. Among these, sodium, potassium, and chloride are the most essential physiological ions and are routinely measured to assess hydration, kidney function, and overall metabolic health.

Absorption and Excretion of Electrolytes
These critical ions are mainly obtained through the diet, absorbed in the gastrointestinal tract, and excreted by the kidneys. Maintaining a proper balance of these electrolytes is crucial for healthy cellular and organ function.

Role of Sodium in the Body
Sodium is the primary extracellular cation and is essential for:

Maintaining fluid balance throughout the body

Regulating osmotic pressure

Supporting nerve and muscle function

Causes of Low Sodium Levels (Hyponatraemia)
Decreased sodium levels can occur due to:

Prolonged vomiting or diarrhoea

Impaired sodium reabsorption by the kidneys

Excessive fluid retention, as seen in heart or kidney disorders

Causes of High Sodium Levels (Hypernatraemia)
Elevated sodium levels may result from:

Significant fluid loss through sweating or dehydration

High dietary salt intake

Increased renal reabsorption of sodium

Private Electrolyte Testing in Slough and Surrounding Areas
Comprehensive electrolyte testing, including sodium, potassium, and chloride levels, is available in Slough, Windsor, Maidenhead, and nearby Berkshire areas. These tests are essential for diagnosing electrolyte imbalances, supporting kidney function assessment, and guiding treatment for various metabolic and fluid-related conditions.
