    10 Questions to Ask Your Doctor About DVT

    1. What is DVT? And how dangerous is it?

    DVT stands for deep vein thrombosis, a blood clot in one of your body's deep veins, usually within a muscle of your leg.

    How Weight Affects DVT

    Obesity has more than doubled since 1980 worldwide. The number of deep-vein clots is rising right along with that. Doctors aren't yet sure exactly why, but people who have a body mass index of at least 30 are more likely than people of normal weight to get a blood clot deep in a vein, called deep vein thrombosis, or DVT.

    The biggest danger is that part of the clot could break off and travel to your lungs. It could cause a blockage known as a pulmonary embolism, or PE. Your doctor will talk to you about how likely that is to happen with your clot.

    2. Are you sure I have a DVT? How is it diagnosed?

    People with a deep-vein clot in their leg usually have swelling, pain, tenderness, or redness in one leg, but sometimes both.

    Your doctor will do a physical exam. He'll also send you for an ultrasound to see how blood is flowing through your veins. He may use other imaging tests and blood tests to confirm the diagnosis.

    3. How did I get DVT? What causes it?

    You can get a clot when you're sitting still for hours, like on a long plane ride or car trip. One can form after surgery and a long hospital stay. Women who take hormones such as estrogen in birth control pills or after menopause are more likely to get a clot.

    You should talk to your doctor to figure out what led to yours.

    4. How will you treat my DVT?

    Your doctor will likely start by giving you shots of heparin. It's a kind of drug called a blood thinner that makes it harder for your blood to clot. Then, you may need to take blood thinner pills, such as apixaban (Eliquis), dabigatran (Pradaxa), edoxaban (Savaysa), rivaroxaban (Xarelto), or warfarin (Coumadin). If you take warfarin, you'll need to get your blood checked often, too.

    Blood thinners won't break up the clot; your body must do that over time. But they will keep it from getting any bigger and prevent more from forming.

    5. How long will I have to stay on blood thinners?

    It depends on what caused your clot. Someone who's had DVT typically takes blood thinners for 6 months. If the clot had just one cause, like surgery, and you don't have any other risk factors for DVT, it might be less time. If it was because of an inherited condition or an ongoing (chronic) disease, it could be longer.
