What Causes DVT?

• The precise cause of DVT, while currently not clear, appears to be related, in part, to long periods of sitting and inactivity
• The decrease in activity may lead to inadequate circulation of the blood in the legs
• In addition, the legs might be slightly constrained, which could also slow down blood flow in the legs
• Other conditions which affect blood flow or normal clotting mechanisms may make some people more at risk of developing DVT
