How to prevent clots in the legs and lungs

Deep- vein thrombosis (DVT) refers to clots that form in the large veins of the arms, legs, or pelvis.

Addressing risk factors for heart disease help to prevent both DVT and PE: Eat a healthy diet, don’t smoke, and exercise regularly. If DVT or PE strikes, anticlotting drugs (anticoagulants) can treat it. Some people may need to take anticoagulants indefinitely to prevent a second vein clot.
