Picture yourself soaring above the clouds, chasing the sunset to an exotic destination, when a silent and possibly deadly enemy starts creeping along your veins—deep vein thrombosis (DVT). This condition is alarmingly exacerbated by long-haul flights. It might sound like a plot twist from a thriller movie, but experts at Pureveins.com will tell you it’s not fiction. In this blog post, we’ll reveal five scientifically-backed tips to arm you against this airborne adversary and ensure your travels take you to memories, not medical emergencies!
Understanding Flight-Related DVT
Deep vein thrombosis (DVT) is a medical condition that arises from the formation of blood clots in deep veins, often in the lower leg. Flight-related DVT can occur when a passenger sits for an extended period in an airplane seat without adequate movement, leading to slower blood flow in the lower extremities and resulting in the development of clots. Despite being a common issue, there are still misconceptions surrounding DVT during flight among the public.
In 2000, tennis star Serena Williams experienced DVT on a transcontinental flight to Paris. She later revealed that while she knew about the risk of blood clots and tried to move around during the flight, she still developed DVT and was ultimately treated for a pulmonary embolism. This serves as an example that even professional athletes who are aware of the risks can still experience DVT.
Despite some common beliefs that only long-haul flights cause DVT, short flights can also result in blood clots just as easily. The issue is typically sitting for more than four hours without taking any breaks for movement or performing leg exercises.
Although air travel has been considered one of several causes of DVT since 1954, it wasn’t until the 1980s that evidence started to accumulate linking airline flights with thrombotic events. According to studies conducted by aviation medical experts and researchers, passengers on prolonged flights have a seven-fold increase in their risk of developing DVT compared to non-travelers.
It is useful to think about how blood flows through our bodies during a flight. Our leg muscles help pump blood back up to the heart as we walk or perform other activities regularly. However, sitting still for extended periods damages that pumping mechanism, leaving blood trapped inside veins that make it harder to get back up to the heart. It would be similar to a bucket of water being blocked from flowing uphill; the water also accumulates in a low spot.
Risk Factors During Air Travel
While anyone can develop DVT while traveling, regardless of age or gender, some travelers are at higher risk than others. Knowing these factors may help individuals take the necessary precautions and measures before and during flights.
Those who have experienced blood clots before or have family members with a history of blood clots or genetic clotting disorders are more likely to develop them again. Additionally, individuals undergoing hormone therapy in conjunction with estrogen-containing contraceptives may be more prone to clotting issues. Hormone replacement therapy after menopause can also create an increased risk of blood clots in susceptible women.
A person’s medical history should be taken into account when determining if they’re at increased risk of developing DVT on long-haul flights. This is comparable to how we would evaluate someone’s risk for hypertension, diabetes, or cardiovascular disease based on their genetics, lifestyle habits, and other health factors.
Obesity has also been linked to DVT as it is associated with lower extremity venous stasis (a state where blood fails to move effectively through the veins) and increased inflammation in tissues surrounding the veins, both of which make clotting more likely. Cancer patients or those recently undergoing chemotherapy treatment are similarly at higher risk for blood clots, especially if they sit still for prolonged periods due to weakened immune systems, vascular damage, or compromised movement capability.
Despite taking all possible precautions, unfortunately, it is not always possible for some people not to get DVT during air travel. There are many reasons people have to choose air travel as their transportation mode, and a history of DVT or increased risk might not make it feasible to avoid flights altogether. In such cases, early recognition of symptoms and seeking prompt medical help can save lives.
Consequently, in the next section, we will talk about recognizing the symptoms of DVT and what measures can be taken to prevent it.
Recognizing Symptoms in Flight
When you fly, it is essential to be aware of the symptoms of Deep Vein Thrombosis (DVT), as early detection is critical for treatment. As we’ve already seen, DVT can lead to life-threatening complications, such as a pulmonary embolism, which can be fatal. In this section, I will provide guidance on how to recognize the signs and symptoms of DVT on a flight.
The most common symptom of DVT is swelling and pain in the leg. If you experience any swelling that doesn’t subside or pain that worsens when standing or walking, it could indicate the development of DVT. You should also look out for skin discoloration, warmth, and tenderness over a vein.
Other symptoms of DVT include sudden shortness of breath, a faster than normal heartbeat, pain in your chest that worsens when you cough, or lightheadedness, which are additional signs that suggest blood clots have dispersed towards the lungs.
It is worth noting that most passengers experience no symptoms at all. However, if you notice any significant changes in your body during the flight, no matter how small, it’s best to communicate with a flight attendant or healthcare professional if they prescribe onboard.
I always try to take extra precautions against developing blood clots on flights since I experienced mild swelling and discomfort in my leg after a long-haul flight a few years ago. While boarding on a business-long haul trip from Spain to China, I noticed my right calf felt tight and painful after takeoff. My leg then began to feel numb, with moderate but noticeable swelling eventually appearing on my ankle and foot – feeling heavy like an elephant avoiding water.
I immediately notified my airline crew about my health concerns, giving them an indication of the current events that had happened previously and what I thought might be related to my situation too. They quickly asked if I needed any medical attention, checked for my vital condition, and brought me some ice bags to reduce the swelling on my leg. The crew was supportive during the whole flight. Nevertheless, they recommended that when I landed, I should seek immediate medical care.
Recognizing the early signs of DVT is crucial to avoiding its complications. If you notice any symptoms, no matter how small, you need to seek help immediately. It’s not worth waiting for your condition to worsen before taking action. Next, let us explore proven prevention measures that will help decrease the likelihood of experiencing DVT on a flight.
Effective Prevention Methods for DVT on Flights
Fortunately, there are several effective and straightforward ways to prevent DVT while flying. By keeping active during your journey through controlled movement or specific exercises and paying attention to clothing selections and attire that optimize blood circulation in your body within confined spaces, you’ll be less likely to develop blood clots on flights.
Doing exercises like calf raises, heel raises, and hip flexes every couple of hours while walking around can remarkably affect your body’s chances of developing blood clots. Exercise encourages healthy blood flow in our limbs by aiding veins that roll between muscles like a tube, squeezing their contents towards the heart.
Regular stretching can also boost circulation by activating muscle groups throughout your legs and lower back, which also helps avoid stiffness often experienced during long flights.
Maintaining awareness of the seated position is also key to reducing blood clot risk during long haul trips. It improves flow and loosens up natural tension points such as thighs or lower back.
Wearing loose-fitting clothing can enhance your comfort level by increasing blood flow within tight spaces naturally found inside the body, enabling continuous air circulation beneath clothes and allowing just enough reprieve from possible compression, limiting vein activity over time.
Also, wearing compression stockings or other products like knee-high socks helps reduce soreness, swelling, and leg fatigue by increasing blood flow and beneficially lowering gravity-driven pooling of blood in the lower legs. This clothing eliminates or reduces friction on the skin holding clothes firmly in place while allowing for air to move around – easing comfort in-flight.
Studies show that compression stockings can be effective in reducing the occurrence of DVT. A clinical study conducted on its implementation showed that passengers wearing compression stockings during a long flight (8 hours or more) had significantly less leg swelling and reduced symptoms of DVT at both 24 hours and one week post-flight than those who didn’t wear them altogether.
Additionally, several other measures can lower the risk, according to medical professionals specializing in DVT. Dietary precautions also play a role in maintaining hydration levels by avoiding foods high in salt content, which could eventually swell ankles, making periods of limited physical movement or pre-existing risk factors worse in cases where they exist.
However, one argument against actively preventing DVT is that exercises and attire choices are seen as uncomfortable because of their tightness or inconvenience for casual passengers. While this may hold true at certain times, not taking simple proactive measures such as exercise may result in life-threatening complications for otherwise healthy individuals – especially when existing risk factors such as weight, age, family medical history, or other conditions with little warning signs threaten lives.
Leg Exercises and Controlled Movement
As mentioned before, extended periods of immobility can increase the chances of developing deep vein thrombosis (DVT). Therefore, it is essential to keep moving during long flights to reduce the risk of blood clotting.
Some practical leg exercises that help prevent DVT include contracting and releasing your calf muscles, rotating your ankles, and flexing your feet up and down. If you have the chance, take short walks around the cabin every couple of hours. This will keep your blood circulating and prevent clotting.
According to a study from the Journal of Thrombosis and Haemostasis, passengers on longer flights who performed regular calf exercises during their travels had a significantly lower incidence of DVT than those who did not exercise.
While some may argue that it is challenging to leave your seat frequently during long flights, these same individuals may be surprised at how easy it can be to perform simple leg exercises while seated. Even if you are unable to get up from your seat, there are still several exercises you can do for your legs while in-flight.
Now that we’ve gone over the importance of regular leg movement on long flights, let’s talk about another critical factor in preventing DVT: attire choices.
Importance of Attire Choices
The clothing you choose to wear on flights can significantly impact your chances of developing DVT. Tight-fitting clothing, especially around the waist or thighs, can restrict blood flow through the veins. It’s best to avoid tight clothes altogether and opt for loose-fitting outfits instead.
A study published in The Lancet medical journal found that women who wore compression stockings during long-haul flights had a much lower risk of developing DVT.
Compression stockings act like an extra layer of muscle in your legs by gently squeezing your veins and helping to keep your blood flowing correctly. Think of it as a gentle hug for your legs that helps prevent DVT from forming.
When preparing for your next flight, consider wearing comfortable and loose-fitting clothing like sweatpants or leggings and avoiding tight jeans or pants. You could also invest in compression stockings, which can provide an extra layer of support for your legs during longer flights.
Some may argue that compression stockings are uncomfortable or pricey, but there are several budget-friendly options available that can be incredibly effective at reducing the risk of DVT.
Now that we’ve discussed the importance of attire choices, let’s move on to what to do after a long-haul flight with regards to medical help.
Deep Vein Thrombosis Treatment
In some cases, the symptoms of DVT might go unnoticed during a flight, so it’s essential to know the appropriate treatment once you’ve landed. DVT is treatable, and failing to act on a blood clot can lead to severe health consequences such as pulmonary embolism, stroke, or even death.
The most common form of treatment for DVT is medication that helps thin your blood. Anticoagulant medications prevent existing clots from growing and new ones from forming. The period for taking this medication may vary depending on how rapidly your body dissolves the clot. In some cases, individuals might have to take this medication for up to three months after the initial diagnosis.
Compression stockings are also an effective tool to relieve pain and prevent swelling in the legs. You can purchase them over-the-counter at drug stores or online, but it’s crucial to buy the correct size. If they’re too loose, they won’t do their job correctly, and if they’re too tight, they could be uncomfortable and cause further problems.
More critical cases of DVT may require thrombolysis, which involves injecting medicine directly into the clot to dissolve it quickly. This treatment method is typically only reserved for extreme cases where an individual has a higher risk of developing life-threatening complications.
If taking blood-thinning medication or wearing compression stockings does not alleviate the symptoms of DVT, surgical treatment methods might be necessary. One of these procedures is called thrombectomy, which involves physically removing large clots from within your veins.
It’s crucial to note that even with suitable treatment methods available, there is still debate around medical intervention for people who have had blood clots in their legs while traveling on planes. Some medical professionals argue that standard anticoagulant therapy isn’t always needed if the individual’s risk of blood clots is low. In these cases, monitoring and frequent check-ins with your doctor might be all that’s necessary.
Just like sun exposure can cause skin cancer, extended periods of sitting on an airplane can increase your risk of developing DVT. It’s like any other potential health risk; you must take preventative measures, such as practicing leg exercises during a long plane ride, to mitigate the risk. Similarly, if you do develop symptoms of DVT, you must seek medical attention and follow their recommended treatment methods.
Remember to stay vigilant throughout your flight and take preventative measures by stretching your legs, wearing compression stockings, drinking water, and walking around the cabin when possible. If you begin to feel discomfort or notice a change in sensation in your legs while traveling, seek medical attention as soon as possible.
