2 a person who travels by plane or by train. The higher incidence of deep venous thrombosis of lower extremity, also because of long waist brake, venous return is obviously slowed down, prone.

3 elderly. The blood coagulation factor activity is higher in the elderly, and the role of leg muscles to promote blood circulation is weakened, so it is easy to suffer from the disease.

The sedentary, long lying, standing for a long time why easily lead to venous thrombosis?

The three major causes of venous thrombosis is blood stasis, vascular endothelial injury and blood composition change, those factors can cause these three changes are prone to cause venous thrombosis. A long time to maintain a posture unchanged, sedentary, long lying standing for a long time will cause the venous return slows down, leading to venous blood stasis, which led to the formation of venous thrombosis. It can not be a long time to maintain a posture unchanged, if the nature of the work had to be sedentary or stand, to be good at self adjustment, over a period of time to change the posture, such as sedentary office work, after a period of time can stand up and move around, can prevent the formation of venous thrombosis.
