  • Immobility (including prolonged inactivity, long trips by plane or car)
  • Smoking.
  • Oral contraceptives.
  • Certain cancers.

  • Pregnancy.
  • Prolonged bed rest due to surgery, hospitalization or illness.
  • Long periods of sitting such as car or plane trips.

What makes you at risk of blood clots?

These risk factors can include surgery, trauma, pregnancy, hormonal therapy, and immobility. If your blood clot was unprovoked, you have no major clinical risk factors, but could instead have underlying risks. These could include a family history of thrombosis, active cancer, and thrombophilia.
