"Hypovolemic Shock"

Hypovolemic shock is a dangerous condition in which your heart can’t get your body the blood (and oxygen) it needs to function. This happens when one lost a large amount of your blood volume, or  from losing a large amount of fluids after a lot of diarrhea, throwing up or sweating.

Hypovolemic shock severely limits the body’s ability to get blood and oxygen to all of the organs. This can lead to organ failure, which can be deadly. The body makes the brain and heart the top priority for receiving oxygen, leading to the arms and legs can getting cold as the blood they would normally receive is sent to the vital organs.
