Step 1 / 1 · Severe symptoms present?

Are there severe (cerebral edema) symptoms?

💡 Hyponatremia = serum sodium <135 mmol/L (mild 130–134, moderate 125–129, severe <125). Severe symptoms: seizure, coma/marked altered consciousness, respiratory distress, severe vomiting — indicating cerebral edema and needing emergency treatment regardless of the absolute sodium or acuity.
