Hypovolemic shock

Hypovolemic shock is a medical emergency and an advanced form of hypovolemia. It is caused by low amounts of blood and/or fluid inside the human body to let the heart pump enough blood to the body.^[1]

Hypovolemic shock happens when there is a low amount of intravascular volume to the point of heart failure. The hypovolemic shock could be due to severe dehydration or from blood loss.^[2][3]

The term hypovolemia refers collectively to two distinct disorders: (1) volume depletion, which describes the loss of sodium from the extracellular space (i.e., intravascular and interstitial fluid) that occurs during gastrointestinal hemorrhage, vomiting, diarrhea, and diuresis; and (2) dehydration, which refers to the loss of intracellular water (and total body water) that ultimately causes cellular desiccation and elevates the plasma sodium concentration and osmolality.
