Deep Vein Thrombosis
Deep Vein Thrombosis (DVT) occurs when a blood clot forms in a deep vein, often in the legs. It can cause swelling, pain, and other complications, but may also occur without noticeable symptoms. Awareness and understanding of DVT are important for overall health.
Cardiovascular- What exactly is deep vein thrombosis?MedlinePlusMay 2026
Deep vein thrombosis (DVT) is a blood clot that forms in a vein deep inside your body, usually in the lower leg or thigh. If the vein swells, it's called thrombophlebitis, and the clot can be dangerous if it breaks loose and travels to your lungs.
- Why does blood clot in my veins?MedlinePlusMay 2026
Blood clots form when blood flow slows down or when there's damage to a vein. Sitting still for long periods, certain medicines, and some health conditions can increase your risk of clotting.
- Am I more likely to get DVT than others?MedlinePlusMay 2026
Yes, some people are more likely to get DVT than others. Risk factors include sitting still for long times, certain medicines, and disorders that make your blood more likely to clot.
- Can sitting still for long periods cause DVT?MedlinePlusMay 2026
Yes, sitting still for a long time—like on a long car or plane trip—can make you more likely to get a DVT. Taking breaks to walk, stretch your legs, and drinking plenty of water can help prevent clots.
- Will I always have symptoms like pain or swelling?MedlinePlusMay 2026
No, not everyone with DVT has symptoms. Common signs include pain or swelling in the affected area, warmth and tenderness over the vein, and skin redness, but some people may have no symptoms at all.
