Risk Factors for DVT

A deep vein thrombosis, or DVT, is a blood clot that forms in the deep veins, usually in the legs. The condition can be very dangerous if the clot travels to the lungs. There are many risk factors for developing a DVT, and some are more preventable than others.

Controllable Risk Factors

• A DVT can develop from long periods of inactivity, such as sitting for long car or plane trips or prolonged bed rest. Obesity and smoking can also increase the risk of developing a DVT.

Preventing Controllable Risk Factors

• Take frequent breaks during long car trips or get up to walk during a long flight if permitted. Engage in regular physical activity and follow doctor-recommended range of motion exercises during bed rest to improve circulation.

Uncontrollable Risk Factors

• Factors including a family history of blood clots, an inherited clotting condition and certain cancers or cancer treatments can increase the risk of a DVT, especially when combined with other risk factors.

Preventive Treatments

• Patients at high risk for developing a DVT may be given preventive treatments, including blood thinners such as heparin and warfarin. According to the Mayo Clinic, special compression stockings may also be used to keep the blood circulating.

Considerations

• A DVT can cause a potentially fatal condition called pulmonary embolism. If you experience symptoms such as sudden shortness of breath, chest pain, coughing up blood or a feeling of panic, seek emergency medical attention.
