It is important to understand your risk for a blood clot. Knowing your risk can help you prevent blood clots, including blood clots in the arm or legs (deep vein thrombosis or DVT) and life-threatening blood clots in the lung (pulmonary embolism or PE). While blood clots can affect anyone, there are certain risk factors that put some people at a greater risk than others.
Blood Clot Risk Factors:

- Immobility, such as confinement to a bed or a wheelchair
- Estrogen-based birth control pills, patch or ring
- Treatment of menopause symptoms with estrogen
- Pregnancy, or the recent birth of a child
- Prior blood clot or family history of blood clots
- A genetic or acquired blood clotting disorder
- Cancer and some cancer treatments
- Some heart and lung conditions, and diabetes
- Sitting for long periods of time, such as at a desk or for extended travel, especially with crossed legs
