DVT – how to avoid them while flying

(DVT – a  disclaimer – I am not a Doctor and I am NOT qualified to offer medical advice. This is just what I do. I have had blood clots before and it wasn’t pleasant.)

Sorry, this is not a fun subject but is very necessary. It is rare to get a DVT but they can be lethal. Blood clots can kill but taking a few simple precautions can dramatically reduce the risk of developing a DVT. They can happen to anyone but there are a few people who are more at risk than others. This is in no way a comprehensive list and more info can be found here but if you suffer from;

  • Pre-existing medical condition
  • if you have a history of DVTs
  • heart disease
  • recent surgery on the lower half of your body
  • obesity

you are at an increased risk.

What is a DVT

Deep vein thrombosis (DVT) is a condition where a blood clot can develop in the deep veins usually in the lower extremities.

How it is caused

Blood clots occur when blood thickens and clumps together.  A blood clot in a deep vein in the leg may move. It can break off and travel through the bloodstream, moving through the body to the lungs or other organs and cause death.


  • swelling, pain and tenderness in the legs (usually your calf)
  • warm skin in the area of the clot
  • a heavy ache in the affected area


How to avoid

  • Calf muscle exercises
  • Walkabout regularly
  • Try and walk about or even on the spot frequently
  • Properly fitted travel socks


All the above should not put you off flying. It’s a rare thing to happen and taking these simple precautions can help. If you are worried about this for an upcoming flight, consult a medical professional. I am not a doctor and offer no medical advice as such. This is just what I do, I have suffered from arterial blood clots and this helps me.

Disclaimer once again. I am not a Doctor. But I do suffer from blood clots and am on long term medication for them. These tips help me and they may help you. Always seek advice from a medical professional.
