Do you have deep vein thrombosis (DVT)?

What is DVT and how can you prevent it? Read on for handy tips.

DVT is linked to prolonged periods of inactivity. The following could make you more prone to DVT:

  • A tendency of blood clotting
  • Recent surgery, particularly leg surgery, injury or swelling within six weeks prior to flying
  • Prolonged immobility, particularly a paralysed lower limb(s)
  • Previous or current DVT, or family history of DVT
  • If you are over 40 years of age
  • If you are taking the oral contraceptive pill and some other hormone treatments
  • If you are pregnant
  • If you have varicose veins
  • Recent heart disease
  • Current malignant disease or chemotherapy
  • Blood disorders
  • Depletion of body fluids causing increased blood thickening
  • Or if you have suffered from a stroke within 6 weeks prior to flying


Things to do during flight


As immobility poses the greatest risk in developing DVT, to reduce the risk during your flight we advise the following:

  • Move about the cabin.
  • Change position frequently.
  • Avoid crossing your legs.
  • Do exercises in your seat.
  • Drink plenty of water before, during and after the flight.


If you may be prone to DVT you must be assessed by your medical practitioner prior to flying who will provide you with further advice and perhaps some medication. If you are at risk you should not rely on aspirin to prevent DVT. Always consult your doctor or medical practitioner.
