Sodium 150 mEq/L: What It Means

Classification: Elevated

Sodium 150 is elevated hypernatremia — significant water deficit. Elderly patients and those who can't access water are most at risk.

What can cause this?

Severe dehydration
Impaired thirst (elderly, stroke)
Diabetes insipidus
Osmotic diuresis (high glucose)

About the Sodium test

Sodium reflects water balance — the ratio of total body sodium to total body water. Kidneys regulate both; kidney disease disturbs the balance.

Standard blood test.
