Three Common Causes of Deep Vein Thrombosis

Varicose VeinsDid you know that clot formation in the legs may have adverse effects on the vital organs of the body? In fact, some individuals ignore usual symptoms such as leg pain, tenderness, and swelling, which are highly indicative of deep vein thrombosis (DVT). This leads to increased size of the occlusion, which further inhibits blood flow to the leg. In order to prevent DVT, you must know the several factors that increase the risk of clot formation in the legs.

Lying Down or Sitting for Prolonged Periods

Muscle movement is one of the major factors that propel blood flow in the veins. The calf muscles force blood in the iliac veins, which are major vessels that return deoxygenated blood back into the normal circulation. Thus, lack of calf movement when lying down and sitting for prolonged periods increases the risk of blood pooling in the lower extremities. Since blood accumulates in the legs, there is a higher likelihood of clot formation.

Previous DVT

Patients with previous history of clot formation have a 30% increased risk of having deep venous thrombosis. It may be attributed to the innate characteristics of your blood components or incomplete dissolution of the previous clot. Unfortunately, some blood clotting disorders may cause your blood to become thicker than usual.

Medication Intake

Some medications may alter the dynamics of clot formation and dissolution. For instance, hormone replacement therapy and birth control pills contain high levels of estrogen, which causes blood to clot more easily. Other examples include antifibrinolytics such as tranexamic acid and aprotinin, which are primary interventions among trauma patients to reduce blood loss. These drugs interfere with the normal blood clotting pathway, which then results in increased incidence of DVT.
