What happens in disseminated intravascular coagulation (DIC)?

First, DIC creates many small blood clots that might keep your blood from traveling through your body. When this happens, your blood might not be able to bring oxygen and nutrients to your head, heart and other organs. Then, having used up the proteins and platelets that make your blood clot, DIC might cause uncontrollable internal or external bleeding.
