Understanding DVT Risk Factors
DVT risk stems from several well-established factors that often compound when combined.
Immobility
Long flights, car trips, or bed rest all raise risk by slowing blood flow in the legs.
Recent surgery
Especially orthopedic or major abdominal surgery, due to both immobility and the body's clotting response to injury.
Hormonal factors
Birth control, hormone replacement therapy, and pregnancy all meaningfully increase risk.
Other medical factors
Cancer treatment, certain genetic clotting disorders, and obesity also contribute to elevated risk.
Key takeawayDVT risk factors — immobility, surgery, hormones, and certain medical conditions — compound when combined, making awareness of your specific combination important for prevention.
