2. Anaphylactic shock is a type of severe
hypersensitivity or allergic reaction. Causes
include allergy to insect stings, medicines, or

damaged and unable to supply sufficient blood
to the body. This can be the end result of a
heart attack or congestive heart failure.

4. Hypovolemic shock is caused by severe blood
and fluid loss, such as from traumatic bodily
injury, which makes the heart unable to pump
enough blood to the body, or severe anemia
where there is not enough blood to carry
oxygen through the body.

5. Neurogenic shock is caused by spinal cord
injury, usually as a result of a traumatic
