DVT

DVT Risk Calculator

Travel related deep vein thrombosis (DVT) is a rare but serious condition whereby a blood clot is formed due to inactivity during travel.

Anyone travelling more than four hours, whether by air, car, bus, or train can be at risk of DVT. Blood clots can form in the deep veins during travel because you are sitting down in a confined space for long periods of time. The longer the period of inactivity, the greater your risk of developing DVT.

We have devised a DVT calculator as a quick way to estimate your risk of flight-related Deep Vein Thrombosis. Our DVT Risk Calculator can help you assess your risk of Deep Vein Thrombosis, and point you in the direction of additional preventive measures.

What is DVT?

Deep Vein Thrombosis (DVT) also known as blood clots, can be a serious risk for some long-distance travellers.

Deep vein thrombosis occurs when blood in the deep veins of your body flows sluggishly and ultimately clots, developing a blood clot. Travel-related DVT most commonly occurs in the veins of the calf muscles and the lower leg due to inactivity during travel.

There are not always noticeable symptoms, however, leg or calf pain, redness, swelling, tenderness, or leg cramps are symptoms you should be aware of.

Travel-related DVT is rare in healthy people. Book a GP appointment to discuss with a doctor if you have recently flown and experience these symptoms.

Am I at an increased risk of DVT?

Even if you are a long-distance traveller, the risk of developing DVT is generally very small.

The risk of developing a travel-related blood clot increases with the length of time you will be flying.

Blood clots are more common in people over 50 but other factors can increase your risk, including:

  • Recent surgery or injury (within 3 months)
  • Cancer or recent cancer treatment
  • Obesity
  • A family history of blood clots and/ or Deep Vein Thrombosis
  • Birth control pills or undergoing hormone therapy
  • Smoking
  • Varicose veins

Should I talk to my doctor about DVT?

Yes

Yes, if you think you are at an increased risk of travel-related DVT and would like more information you should talk with your doctor or a travel nurse during your travel consultation. Recommendations can be made to help lower your risk.
