Dic (Disseminated intravascular coagulation) is the state where proteins in the blood involved in blood clotting become overactive. This condition may stop blood flow to major parts of the body like kidneys and liver. Excessive bleeding can occur because of the abnormal activity of blood clotting. Haemostasis is a process where bleeding is stopped when injured. However, this process may not take place in some cases because sufficient platelets will not form together to form a clot. This condition activates DIC. DIC disable blood and oxygen supply to the injury area and prevent blood clots leading to multiple clots. Internal organ (nose and mouth) bleeding may occur. Extensive bleeding may occur during infection, cancer treatments, surgery and serious complication may occur during pregnancy.
