Flight Blood Clot Risks: Doctor’s Advice for Safe Air Travel
Many individuals eagerly anticipate the relaxation flights offer at the start of a holiday. However, medical professionals recommend that travellers proactively take steps to mitigate the potential health risks associated with air travel, particularly concerning blood clots. Much like pilots perform pre-flight checks, passengers should also prepare themselves to ensure a healthy journey.
Deep Vein Thrombosis (DVT) and Long-Haul Flights
Dr. Dana Digura, a foot surgeon, has highlighted the danger of Deep Vein Thrombosis (DVT) during long-haul flights. DVT is a potentially serious condition that can arise from extended periods of immobility and reduced blood circulation in the legs during air travel, increasing the likelihood of blood clot formation. This risk is heightened on flights exceeding four hours, sometimes referred to as “economy class syndrome.”
Dr. Digura emphasizes that certain individuals face a greater risk of DVT during flights, including:
- Individuals using birth control pills
- Pregnant women
- Obese individuals
- People who have recently undergone surgery
- Smokers
- Individuals with varicose veins
Heightened Risk on Longer Flights
Expanding on this, Dr. Digura noted that “The risk is even greater for flights lasting over six hours.” This underscores the importance of taking preventative measures, especially on extended journeys.
Expert Agreement on Blood Clot Risks
Dr. Danielle Bajakian, a vascular surgeon and director of the Vein Program at Columbia University Department of Surgery, corroborated this health advisory. She clarified, “Your veins require movement to effectively circulate blood from your feet back to your heart. Remaining stationary for prolonged periods increases the possibility of blood clot development.”

Preventative Measures for In-Flight Blood Clots
Simple Tips to Improve Blood Flow
Dr. Digura offers crucial guidance for travellers concerned about blood clots during flights. Her advice is straightforward and actionable:
- Walk Regularly: “Try to stand up and walk around every hour. This helps activate the calf muscles and prevents blood from accumulating in your legs.”
- Calf Muscle Exercises: “Even if you are unable to walk, you can engage your calf muscles with foot pumps, calf raises, and ankle circles while seated.”
Compression Socks for Enhanced Circulation
The medical expert also suggests compression socks as a protective measure against blood clots for all age groups during flights. “You can purchase compression socks…they aid in reducing swelling and improving blood flow.”
Retailers confirm these benefits, explaining that “A simple pair of socks can significantly improve circulation, support veins, and prevent leg swelling, blisters, shin splints, and general aches and discomfort.”
Public Response and Awareness
Social media users have promptly expressed both worry and gratitude for Dr. Digura’s expert perspectives. One individual shared their concern: “This is absolutely my biggest fear. I travel internationally frequently on long hauls, and I am a plane sleeper, often sitting for 3+ hours without moving!”
Another person conveyed relief, stating: “Thank goodness I saw this before my upcoming 23-hour flight next weekend.” This highlights the timely and relevant nature of the expert advice provided.
Seeking Medical Advice
For those with concerns about blood clots or blood circulation, it is recommended to consult the relevant health service website or speak with a General Practitioner. In case of DVT symptoms accompanied by breathlessness or chest pain, immediate medical attention is crucial. Seek emergency services without delay.
