What are the common symptoms of hypervolemic hyponatremia?

Symptoms of hyponatremia may vary depending on the severity of the imbalance as well as what is causing the imbalance. Symptoms tend to be similar in some ways, but may also vary depending on whether one has hypervolemic, hypovolemic, or isotonic hyponatremia. 
People experience hypervolemic hyponatremia will often present with symptoms associated with their related conditions and the discovery of the electrolute imbalance is incidental. Potential symptoms of hypervolemic hyponatremia include:
  • Edema (swelling due to excess fluid volume)
  • Shortness of breath
  • Cough
  • Nausea 
  • Malaise
  • Headache
  • Vomiting
  • Confusion
  • Fatigue
  • Restlessness
  • Irritability
  • Muscle weakness, spasms, or cramps
  • Lethargy/decreased level of consciousness
