What is DVT?
Deep vein thrombosis (DVT) occurs when a blood clot (thrombus)
forms in one or more of the deep veins in your body, usually in your legs. Deep
vein thrombosis can cause leg pain or swelling, but may occur without any
symptoms.
Deep
vein thrombosis can develop if you have certain medical conditions that affect
how your blood clots. Deep vein thrombosis can also happen if you don't move
for a long time, such as after surgery, following an accident, or when you are
confined to a hospital or nursing home bed.
Deep vein thrombosis is a serious condition because blood clots
in your veins can break loose, travel through your bloodstream and lodge in
your lungs, blocking blood flow (pulmonary embolism).
Prevention
To prevent deep vein thrombosis, some common
preventive measures include the following:
Avoid sitting still. If you're sitting for a while, try not
to cross your legs because this can limit 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,
try to stand or walk occasionally. If you can't do that, at least try to
exercise your lower legs. Try raising and lowering your heels while keeping
your toes on the floor, then raising your toes while your heels are on the
floor. If you've had surgery or have
been on bed rest for other reasons, try to get moving as soon as possible.
Get
regular exercise. Exercise lowers
your risk of blood clots, which is especially important for people who have to
sit a lot or travel frequently.
Make
lifestyle changes. Lose weight and
quit smoking. Obesity and smoking increase your risk of deep vein thrombosis.
Take
any prescribed medications as directed. If you're having surgery, such as orthopedic surgery,
you'll probably be given blood thinners while you're in the hospital. Your
doctor may also prescribe aspirin or other medications that help prevent clots
to be taken for a while after surgery.
