Shock (circulatory)

Okay buddy, so you know how our bodies need blood to stay alive? Blood carries important things like oxygen and nutrients to all the different parts of our body. But sometimes, if something really scary or dangerous happens, our body can go into something called shock.

Shock means that our body isn't getting enough blood to where it needs it. This can happen because something is blocking the blood flow, or because our blood vessels aren't working the way they should. When our body is in shock, it can't get enough nutrients and oxygen, so it starts to shut down.

Some signs that someone might be in shock include feeling really dizzy or lightheaded, having a rapid heartbeat, feeling cold and clammy, or losing consciousness. If you think someone might be in shock, it's really important to get them medical help right away. Doctors can give them fluids or other medicines to help get their blood pressure back up and keep their body working the way it should.
