What is hypovolaemia?

Hypovolaemia is the decrease in blood volume due to loss of blood, plasma and/or plasma water, which is encountered in cases of severe dehydration or blood loss. This eventually results in a loss of intravascular content and limits tissue perfusion. It can be fatal if left untreated.

What are its main signs and symptoms?

The common signs and symptoms of hypovolaemia include:

  • Generalised weakness
  • Paleness of skin (pallor)
  • Cool, clammy skin or sweating, moist skin
  • Rapid breathing
  • Anxiety or agitation
  • Low blood pressure (hypotension)
  • Low or no urine output
  • State of confusion
  • Unconsciousness

What are its main causes?

Hypovolemia can be caused by:

  • Loss of body fluids due to the following:
  • Blood loss due to the following:

How is it diagnosed and treated?

The diagnosis is mainly considered by the physician based on signs and symptoms and a complete physical examination. Further evaluation is done on the basis of the following tests:

  • Blood test to evaluate kidney function, complete blood count (CBC) and damage to the heart muscles
  • X-ray
  • Ultrasound
  • Computed tomography (CT) scan
  • Endoscopy
  • Echocardiogram
  • Right heart catheterisation
  • Urinary catheterisation

Treatment of hypovolaemia includes:

  • The first line of treatment would be measured to replace blood and fluids, which can be achieved by giving various oral rehydrating liquids or intravenous (IV – through veins) transfusion of blood or fluids depending upon the cause of hypovolaemia. Further, to avoid hypothermia, the individual should be made comfortable and warm.
  • In case the cause is an allergy, anti-allergens should be given.
  • In severe cases, to increase blood pressure and cardiac output (the amount of blood pumped out of the heart), medications such as norepinephrine, dopamine, epinephrine or dobutamine may be given.
