Causes When you are injured, proteins in the blood that form blood clots travel to the injury site to help stop bleeding. If these proteins become abnormally active throughout the body, you could develop DIC. The underlying cause is usually due to inflammation, infection, or cancer.In some cases of DIC, small blood clots form in the blood vessels. Some of these clots can clog the vessels and cut off the normal blood supply to organs such as the liver, brain, or kidneys. Lack of blood flow can damage and cause major injury to the organs.Blood clotsBlood clots are clumps that occur when blood hardens from a liquid to a solid. A blood clot that forms inside one of your veins or arteries is calle...ImageRead Article Now Book Mark Article In other cases of DIC, the clotting proteins in your blood are consumed. When this happens, you may have a high risk of serious bleeding, even from a minor injury or without injury. You may also have bleeding that starts spontaneously (on its own). The disease can also cause your healthy red blood cells to fragment and break up when they travel through the small vessels that are filled with clots.Risk factors for DIC include:Blood transfusion reaction Blood transfusion reactionA hemolytic transfusion reaction is a serious complication that can occur after a blood transfusion.

Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.Blood clot formationillustrationMeningococcemia on the calves - illustration Meningococcemia is a life-threatening infection that occurs when the meningococcus, Neisseria meningitidis, invades the blood stream. Bleeding into the skin (petechiae and purpura) may occur. The tissue in areas may die (become necrotic or gangrenous). If the person survives, the areas heal with scarring.Meningococcemia on the calvesillustrationBlood clots - illustration Blood clots (fibrin clots) are the clumps that result when blood coagulates.Blood clotsillustrationBlood clot formation - illustration Blood clotting normally occurs when there is damage to a blood vessel.
