Symptomatic hypervolemic Hyponatremia

Symptomatic Hypervolemic Hyponatremia: An Overview

Symptomatic hypervolemic hyponatremia is a condition in which the levels of sodium in the blood become abnormally low. This can lead to a variety of symptoms including confusion, fatigue, headache, muscle cramps, nausea, restlessness, and vomiting. The condition is typically caused by an underlying medical condition such as congestive heart failure, cirrhosis, liver failure, nephrotic syndrome, or severe burns. Treating the underlying condition can help to control the symptoms of symptomatic hypervolemic hyponatremia.

What Causes Symptomatic Hypervolemic Hyponatremia?

The primary cause of symptomatic hypervolemic hyponatremia is an underlying medical condition that causes excess fluid build-up in the body. These conditions typically result in the excretion of too much sodium in the urine, while the kidneys are unable to remove enough water. This causes the sodium levels in the blood to become abnormally low. The most common underlying conditions that can cause symptomatic hypervolemic hyponatremia include:

  • Congestive heart failure
  • Cirrhosis of the liver
  • Liver failure
  • Nephrotic syndrome
  • Severe burns

Symptoms of Symptomatic Hypervolemic Hyponatremia

Common symptoms of symptomatic hypervolemic hyponatremia include:

  • Confusion
  • Fatigue
  • Headache
  • Muscle cramps
  • Nausea and vomiting
  • Restlessness

Symptomatic hypervolemic hyponatremia can be life-threatening if left untreated. In severe cases, it can lead to coma, seizures, and even death.

Diagnosis and Treatment of Symptomatic Hypervolemic Hyponatremia

Your doctor will diagnose symptomatic hypervolemic hyponatremia by conducting a physical examination and ordering laboratory tests. The tests will measure the levels of sodium in the blood and look for other signs of underlying medical conditions. Treatment options may include medication to reduce symptoms and improve fluid balance, as well as supplemental electrolytes to help restore normal sodium levels in the blood.

It is important to treat any underlying medical conditions that are causing symptomatic hypervolemic hyponatremia. This may involve lifestyle changes, such as reducing sodium and fluid intake or exercise. It may also include medications to help manage the symptoms of the condition.


Symptomatic hypervolemic hyponatremia can be a dangerous condition if left untreated. It is important to seek medical help if you suspect you may have this condition. Your doctor can diagnose the condition and provide treatment to help restore your sodium levels and improve your symptoms.
