	Disseminated intravascular coagulation [[Disseminated intravascular coagulation]] (DIC) is a complex systemic disorder characterized by both widespread clotting and bleeding. It typically arises as a secondary condition in response to an underlying disease or trauma, disrupting the balance between the body's clotting and anti-clotting mechanisms.

	In DIC, the normal hemostatic balance is disrupted, leading to excessive clotting and, paradoxically, a risk of severe bleeding. The pathophysiological process begins with the widespread activation of the coagulation cascade, leading to the formation of microthrombi in the blood vessels. This over-activation depletes the body's reserves of clotting factors and platelets, leading to a coagulopathic state that can result in hemorrhage.

	The diagnosis of DIC is made through a combination of clinical findings and laboratory tests.
