Preparing for a long flight often comes with a myriad of concerns that travelers grapple with, including questions like: Will I be able to sleep? How severe will my jet lag be? Do I have enough snacks for the journey? Among these worries, the risk of developing blood clots may not be top of mind for everyone. However, it’s essential to be aware that flights exceeding four hours can raise the chances of a clot forming in a deep vein, leading to deep vein thrombosis (DVT). If a clot dislodges, it may travel to the lungs, resulting in a serious condition known as a pulmonary embolism.
Research indicates that the average individual has a risk of developing DVT on roughly one out of every 4,656 long flights. While this may seem low, the likelihood increases for those with specific risk factors, such as inflammatory conditions like lupus, ulcerative colitis (UC), chronic obstructive pulmonary disease (COPD), or various cancers. These health issues, along with some medications used for treatment, can elevate the chances of forming blood clots.
For example, a study highlights that individuals with UC and Crohn’s disease are approximately two to three times more susceptible to blood clots than the general population. Georgi Shirley, an independent travel agent from England living with Crohn’s disease, reflects on this increased risk, noting that she has always maintained vigilance regarding clots due to a family history of the issue.
Experts suggest several precautions for those who might be at heightened risk while traveling.
Maintain Flexibility in Travel Plans
Research shows that over 71 percent of individuals with inflammatory bowel disease experience active disease during clot development. This elevation in risk often doubles for those with rheumatoid arthritis during flare-ups. “Flare-ups are likely the most significant risk factor for clots, especially during extended periods of immobility, such as long flights,” explains Dr. Tenzin Choden, a gastroenterologist at the University of Chicago.
To mitigate potential concerns, consider investing in refundable tickets and hotels, should your health condition change before your journey. Shirley emphasizes the importance of flexible arrangements for accommodations and travel insurance tailored to cover any cancellations related to her condition.
Adhere to Medication Regimens
For individuals with inflammatory conditions like UC and Crohn’s disease, the risk of DVT often intensifies during flare-ups. Dr. Choden recommends that travelers remain diligent with their prescribed medication schedules. Being in tune with your health care provider’s guidance is critical before flying, especially if taking medications that may influence clot formation.
Stay Active During the Flight
Long periods of immobility during flights are a primary factor in increased clot risk. It is essential to incorporate movement throughout the journey. “Remember to engage your legs, even if it’s just standing and doing calf raises beside your seat,” advises Dr. Choden. Shirley suggests opting for seats located toward the back of the aircraft, where there is often greater space for movement. If airline seating options are limited, she recommends contacting the airline to discuss any medical considerations; in most cases, they are accommodating.
Consider Compression Stockings
While comfort is key in an outfit for flying, tight compression stockings that extend from your ankles to your calves can be beneficial in reducing DVT risk. “They can help prevent blood from pooling in your lower legs,” Dr. Choden states. These stockings come in various strengths, and it’s advisable to choose a pair that offers between 15 and 20 millimeters of mercury (mmHg) of compression pressure. Consult with your physician to determine the optimal level of compression for your needs.
Be Aware of DVT Symptoms
Recognizing the signs of deep vein thrombosis is crucial. “The most significant risk occurs about one to two weeks following a flight, characterized by persistent pain and swelling in the legs,” warns Dr. Choden. If a clot travels to the lungs, symptoms may escalate to include sudden shortness of breath and chest pain, particularly worsening with inhalation. If you suspect a clot or pulmonary embolism, it is vital to seek immediate medical assistance, as this can be life-threatening.
While the potential for DVT may seem daunting, don’t let it deter your travel ambitions. Shirley advises those with diagnoses like irritable bowel disease to embrace their wanderlust, stating, “Of course, you can travel! It shouldn’t stop you.”
