- Blood clot in a deep vein of a leg or the pelvis
- Increased levels of clotting factors in the blood
- Prolonged bed rest
- Major surgery, especially after pelvic surgery, knee replacement, or heart surgery
- Injury to a vein in a leg or the pelvis
- Fractures of the hip or thigh bone
- Certain blood disorders
- Prolonged sitting, such as during a long trip
- Pregnancy or postpartum period
- Inflammatory bowel disease
- Autoimmune disorder, such as immune thrombocytopenic purpura, polyarteritis nodosa, or polymyositis
- Taking certain medications, such as birth control pills or antipsychotics
- Arterial blood gas study—to check oxygen levels and lung function
- Electrocardiogram (EKG)—to assess the electrical activity of the heart
- D-Dimer blood test—to detect the presence of a clot
If you have a family history of blood clots, and had blood clots in the past for no apparent reason, your doctor may do additional blood tests. The tests will look for possible inherited defects in your clotting system, such as:
- Factor V Leiden mutation (seen in up to 40% of cases)
- Increased factor VIII
- Eat a healthful diet that is low in saturated fat and rich in whole grains, fruits, and vegetables.
- Begin a safe exercise program with the advice of your doctor.
- Walk or move your legs to break up long periods of sitting.
- If you smoke, talk with your doctor on ways you can quit.
- Unless you are on a fluid-restricted diet, be sure to drink lots of water.
- Take medication if your doctor recommends it. Anticoagulant drugs are most commonly used.
- Wear elastic stockings if suggested by your doctor. They can help improve circulation in your legs.
- Walk or move your legs to break up long periods of sitting. If you are traveling, get up and walk every few hours.
