A 33-year-old woman recently experienced a life-threatening incident during a long-haul flight, underscoring the critical importance of in-flight mobility to prevent serious health complications. Emily, known on TikTok as ‘alwayssingingmom’, was on a 13-hour non-stop flight from Toronto to Dubai when she collapsed approximately two and a half hours before landing. Prior to this, she had remained seated for ten hours without moving. Upon standing to use the restroom, Emily experienced a sudden, severe chest pain and lost consciousness shortly thereafter. She was unconscious for about five minutes and, upon arrival in Dubai, was diagnosed with a saddle pulmonary embolism—a large blood clot lodged at the bifurcation of the main pulmonary artery, which can be fatal if not promptly treated.
This incident highlights the dangers associated with prolonged immobility during air travel, particularly the risk of developing deep vein thrombosis (DVT). DVT occurs when a blood clot forms in a deep vein, typically in the legs, and can lead to a pulmonary embolism if the clot dislodges and travels to the lungs. The risk of DVT increases during long flights due to extended periods of inactivity and confined seating, often referred to as ‘economy class syndrome’.
Several factors can elevate the risk of developing blood clots during air travel. These include pre-existing medical conditions such as lupus, ulcerative colitis, chronic obstructive pulmonary disease (COPD), certain cancers, and inflammatory diseases like Crohn’s disease. Additionally, lifestyle factors such as obesity, smoking, and the use of certain medications, including oral contraceptives and hormone replacement therapy, can further increase the risk. Long periods of immobility, dehydration, and cramped seating conditions during flights exacerbate these risks.
Symptoms of DVT can vary but often include swelling, pain, tenderness, warmth, and changes in skin color in the affected leg. However, some individuals may not exhibit noticeable symptoms, making the condition more challenging to detect. If a clot travels to the lungs, it can cause a pulmonary embolism, characterized by sudden shortness of breath, chest pain, rapid heartbeat, and coughing, sometimes with blood. This is a medical emergency requiring immediate attention.
To mitigate the risk of DVT during long flights, travelers are advised to take several precautionary measures:
- Move Regularly: Aim to stand up and walk around the cabin every two hours to promote blood circulation.
- Perform Seated Exercises: Engage in simple leg exercises while seated, such as ankle circles and foot pumps, to stimulate blood flow.
- Stay Hydrated: Drink plenty of water before and during the flight to prevent dehydration, which can increase blood viscosity.
- Avoid Alcohol and Caffeine: These substances can lead to dehydration; it’s best to limit their intake during flights.
- Wear Compression Stockings: These garments apply gentle pressure to the legs, aiding blood flow and reducing the risk of clot formation. It’s advisable to consult a healthcare provider to ensure proper fit and compression level.
- Choose an Aisle Seat: Selecting an aisle seat can make it easier to get up and move around during the flight.
- Consult a Doctor: If you have pre-existing health conditions or are taking medications that may increase clotting risk, seek medical advice before traveling.
Understanding and Preventing Blood Clots During Air Travel
The Science Behind Blood Clots on Flights
When a person remains seated for long durations, especially with their legs bent at the knee, blood circulation slows down. This sluggish blood flow can lead to the formation of clots in deep veins, typically in the lower legs. Under normal circumstances, movement encourages circulation and prevents clotting. However, on flights—where space is limited, and passengers may remain seated for hours—this natural circulation process is disrupted.
The situation becomes even more dangerous if a clot forms and later dislodges, traveling through the bloodstream to the lungs, where it can cause a pulmonary embolism. This blockage can prevent oxygen from reaching vital organs, leading to life-threatening complications.
Risk Factors and Prevention Strategies
- A history of blood clots or family history of clotting disorders
- Recent surgery, particulary involving the lower extremities
- Pregnancy
- Use of hormone based medications, such as birth control pills
- Smoking
- Obesity, which can contribute to poor circulation
To reduce the risk of blood clots while flying, experts recommend the following:
- Frequent Movement: Even if standing up and walking around isn’t always feasible due to turbulence or seatbelt restrictions, travelers can still perform seated exercises. Flexing the ankles, stretching the legs, and rotating the feet can encourage blood flow.
- Hydration: Water helps maintain optimal blood viscosity. Avoiding alcohol and caffeine, which contribute to dehydration, is also recommended.
- Compression Stockings: These specially designed socks apply gentle pressure to the legs, promoting circulation and reducing the chances of clot formation.
- Loose-Fitting Clothing: Tight clothing can restrict blood flow, so wearing comfortable attire is advisable.
- Aspirin (Consult a Doctor First): Some individuals take low-dose aspirin before flying, as it can reduce the blood’s tendency to clot. However, this should only be done under medical supervision.
The Importance of Raising Awareness
Emily’s story has resonated with many people online, especially those who travel frequently for work or leisure. By sharing her experience, she has shed light on an issue that often goes unrecognized. Many travelers are unaware of the potential dangers of remaining sedentary during long flights, and stories like hers serve as an important reminder to prioritize movement and health while traveling.
Final Thoughts
While Emily survived her ordeal and is now advocating for awareness, not everyone is as fortunate. Blood clots can be fatal if not detected and treated in time. The best way to prevent such incidents is through awareness, preparation, and small behavioral changes during flights.
