What Causes Deep Vein Thrombosis?
Many factors affect the development of deep vein thrombosis. While the most common cause is blood pooling or flowing slowly through the legs, injuries to the walls of your veins can also cause clots to form. Causes of DVT include:
- Genetic factors or a family history of DVT
- A medical condition that increases your risk of blood clots
- Limited blood flow in the legs due to immobility
- Spending a long time sitting, such as during travel
- Use of certain medications that increase blood clot risks
- Current or recent pregnancy
- Smoking or using tobacco products
- Age (although young people can develop DVT)
- Being overweight or obese
- Autoimmune conditions
Many people who develop deep vein thrombosis have a combination of risk factors. However, it’s possible to develop the condition without realizing you are at risk. Being aware of the symptoms can help you seek help promptly. With treatment, DVT can resolve without lasting damage.
