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.
