Deep Vein Thrombosis Causes

Anything that slows the flow of blood through the deep veins can cause DVT. This includes injury, surgery or long periods of sitting or lying. For this reason DVT has become associated with hospitalisation and long haul travel (not just air travel).

Other deep vein thrombosis causes and factors which increase your risk of developing DVT include blood clotting disorders, pregnancy and taking the oral contraceptive pill or hormone therapy.
