Hypovolemic Shock

Overview, Causes, & Risk Factors | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

Hypovolemic shock is a condition in which the body doesn't have enough blood volume to circulate throughout the body. The person doesn't receive enough oxygen in vital organs.

What is going on in the body?

Blood, which contains fluid, cells, and other particles, carries oxygen through the body. Oxygen is required to keep body tissues alive. When there is a severe decrease in blood or total body fluid, hypovolemic shock occurs. If this situation is not corrected right away, the person will die.

What are the causes and risks of the condition?

Hypovolemic shock is usually caused by massive blood loss or severe dehydration. Blood loss may be the result of gastrointestinal bleeding, internal bleeding due to an injury, a hemorrhage, or severe burns. Dehydration may follow severe diarrhea or vomiting. It can also be caused by excessive sweating or an inadequate intake of oral fluids.
