What Is Deep Vein Thrombosis?

Q:
What is deep vein thrombosis?

A:
Deep vein thrombosis (DVT) occurs when a blood clot forms in a vein deep inside your body, most likely in your lower leg, thigh, or pelvis. It can occur in other parts of your body, too. Deep vein thrombosis can cause leg pain or swelling, or no symptoms at all.

Deep vein thrombosis can happen if you have certain medical conditions that affect how your blood clots, if you don’t move for a long time, or when you’re confined to bed. It can be very serious because blood clots in your veins can break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow (pulmonary embolism).
