Imagine your body is a delivery truck running low on gas—if the truck can't carry enough fuel, it can't make all its stops. That's what anemia does to your blood, leaving you exhausted because your body isn't getting the oxygen it needs. Have you ever felt so worn out from a long day that you could barely move? Anemia can make you feel like that all the time.
