Prevention

Measures to prevent deep vein thrombosis include the following:

• Avoid sitting still. If you have had surgery or have been on bed rest for other reasons, try to get moving as soon as possible. If you're sitting for a while, don't cross your legs, which can block blood flow. If you're traveling a long distance by car, stop every hour or so and walk around.

If you're on a plane, stand or walk occasionally. If you can't do that, exercise your lower legs. Try raising and lowering your heels while keeping your toes on the floor, then raising your toes with your heels on the floor.

• Don't smoke. Smoking increases your risk of getting DVT.
• Exercise and manage your weight. Obesity is a risk factor for DVT. Regular exercise lowers your risk of blood clots, which is especially important for people who sit a lot or travel frequently.
