How To Avoid DVT On Flight

Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. It can occur during long flights due to prolonged periods of immobility and low cabin pressure. However, there are several strategies you can use to reduce the risk of developing DVT while flying.

🛫 How to Avoid DVT on Flights

✅ 1. Move and Stretch Regularly

  • Walk around the cabin every 1–2 hours. Even just standing up and stretching your legs can help improve circulation.
  • Do in-seat exercises:
    • Ankle circles: Move your feet in circles clockwise and counterclockwise.
    • Leg lifts: While seated, lift one leg at a time and hold for a few seconds.
    • Foot pumps: Point and flex your toes to promote blood flow in the legs.

✅ 2. Stay Hydrated

  • Drink plenty of water before, during, and after the flight to avoid dehydration. Dehydration can increase the risk of blood clots.
  • Avoid excessive alcohol and caffeine, as they can contribute to dehydration.

✅ 3. Wear Compression Stockings

  • Compression stockings can help improve blood circulation in your legs and reduce the risk of DVT.
  • Choose stockings that provide graduated compression (tighter at the ankle, loosening as it moves up the leg) to promote healthy blood flow.

✅ 4. Avoid Crossing Your Legs

  • Crossing your legs for extended periods can restrict blood flow. Try to keep your legs in a relaxed, uncrossed position to allow for proper circulation.

✅ 5. Elevate Your Feet

  • When seated, try to keep your feet elevated slightly (e.g., by using a footrest). This can help reduce pressure on the veins in your legs and improve circulation.

✅ 6. Wear Loose, Comfortable Clothing

  • Tight clothing, especially around the waist and legs, can restrict blood flow. Opt for loose, comfortable clothes to allow for proper circulation during the flight.

✅ 7. Consider Blood Thinners (for High-Risk Individuals)

  • If you’re at higher risk for DVT (e.g., a history of blood clots, recent surgery, or pregnancy), talk to your doctor about the possibility of using blood-thinning medications before and after the flight.

✅ 8. Avoid Prolonged Sitting

  • If possible, try to avoid sitting for extended periods. Instead, get up and walk around the cabin or stretch out your legs when you can.

✅ 9. Maintain a Healthy Weight and Exercise Regularly

  • Regular physical activity can improve circulation and reduce the risk of DVT.
  • Maintaining a healthy weight can also help reduce the pressure on your veins.

✅ 10. Consult a Doctor for Long Flights or Pre-existing Conditions

  • If you’re planning a long-haul flight and have concerns about DVT or any medical conditions that increase the risk, it’s a good idea to consult your healthcare provider before traveling.
  • Your doctor may recommend specific measures tailored to your health needs.

By following these steps, you can significantly reduce your risk of developing DVT while flying and enjoy a safer journey.
