What Are the Causes of Blood Clots in the Legs?
Blood clots occur when the blood hardens from a liquid to a solid. A blood clot that forms inside a blood vessel and remains there is called a thrombus. A deep vein thrombosis, or DVT, usually occurs in the leg veins. Many factors can increase the risk of developing blood clots in the legs, especially if several risk factors occur at the same time.
