1) Disseminated intravascular coagulation (DIC) is a condition where abnormal blood clotting occurs throughout the body's blood vessels, consuming platelets and clotting factors and eventually causing bleeding. 2) DIC is caused by underlying conditions such as infection, injury, cancer or shock and results in microclots forming in small blood vessels. 3) Symptoms of DIC include bleeding, organ dysfunction, and low platelet and clotting factor levels. Treatment focuses on the underlying cause as well as replacing clotting factors and platelets if serious bleeding occurs.
