The risk of developing Deep Vein Thrombosis (DVT) during or after a flight is generally low, but it increases with longer flights and certain risk factors. For healthy individuals, the risk is estimated to be about 1 in 107,000 for flights under 4 hours, and 1 in 4,600 for flights over 4 hours, according to West Suffolk Hospital. For flights longer than 16 hours, this risk can increase to 1 in 1,200.
Factors influencing DVT risk during travel:
- Flight duration: Longer flights increase the risk of DVT due to prolonged immobility.
- Pre-existing risk factors: Certain conditions like obesity, hormonal therapies, and recent surgery can increase the likelihood of DVT.
- Individual factors: Age, height, and body mass index (BMI) can also influence risk.
- Seat placement: Window seats may increase risk compared to aisle seats, potentially due to less freedom of movement.
Precautionary measures:
-
Get up and walk around the plane periodically, and do leg exercises while sitting.
-
Wearing compression stockings can help prevent DVT, especially for individuals with pre-existing risk factors.
-
Staying hydrated can help prevent blood clots.
-
If you have any concerns about DVT risk, consult with your physician for personalized advice.
