What is hypovolemic shock?

Hypovolemic shock is a health emergency. It needs to be treated right away.

During hypovolemic shock, the body has lost too much blood or other fluids. As a result, the body’s vital organs can’t get enough oxygen-rich blood. Without enough oxygen, the body can’t work correctly and death may occur.

What causes hypovolemic shock?

There are two types of hypovolemic shock. They are caused by different things.

Hemorrhagic shock occurs from losing too much blood. The most common cause of this type is trauma, or a bad injury. It can also happen from internal bleeding, such as from an ulcer or a ruptured aneurysm.

Nonhemorrhagic shock occurs from excess fluid loss. This type may happen from:

  • Severe diarrhea or vomiting

  • Heat stroke

  • Burns

  • Gastrointestinal problems, like a bowel blockage

How is hypovolemic shock treated?
