Deep Vein Thrombosis
What Increases Your Risk
Many things increase your risk for deep vein thrombosis (DVT). These include:
- Being older than 40.
- Being overweight.
- Not taking Reference anticoagulant Opens New Window medicine as prescribed.
Other risks include things that cause slowed blood flow, abnormal clotting, and a blood vessel injury.
Slowed blood flow
Blood does not flow normally if you are not active for long periods of time. Examples include:
- Long-term bed rest, such as after a surgery, injury, or serious illness.
- Sitting for a long time, especially when traveling long distances.
- Leg paralysis.
Some people have blood that clots too easily or too quickly. Problems that may cause increased clotting include:
- Reference Inherited blood-clotting problems.
- Family history of close relatives, such as a sibling, who has had deep vein thrombosis or a pulmonary embolism.
- Cancer and its treatment.
- Blood vessel diseases, such as varicose veins, heart attack, heart failure, or a stroke.
- Reference Pregnancy. A woman's risk for developing blood clots increases both during pregnancy and shortly after delivery or after a cesarean section.
- Using hormone therapy or birth control pills or patches.
Injury to the blood vessel wall
Blood is more likely to clot in veins shortly after they are injured. Examples include:
- Recent surgery that involved the legs, hips, belly, or brain.
- Having a Reference central venous catheter during a hospital stay.
- Injury, such as a broken hip.
