When to see a doctor. It’s vital to see a doctor if any of the more severe symptoms of hyponatremia are present or persist for longer than several minutes. These symptoms include faintness, dizziness, confusion/disorientation, or loss of consciousness. Also, nausea or vomiting that occurs with no other obvious cause like eating bad food should be considered a symptom of hyponatremia because the stomach cannot effectively digest food. A doctor can diagnose the condition as sodium deficiency, and if it’s an acute severe episode, refer patients to an emergency room or hospital for immediate treatment if the condition is life-threatening.
