Travel naturally revs up in the summer, bringing the promise of adventure, relaxation, and long-awaited reunions with family and friends.
Our team at Premier Cardiology Consultants in New York City wants you to enjoy your summertime travel. However, because sedentary travel increases your risk for blood clots, we’d like you to take a few precautions along the way.
Whether you are flying across the country or embarking on an international vacation, understanding how blood clots form and how to prevent them can help ensure your summer journey is safe and healthy.
Travel-related blood clots develop when blood flow in the veins slows down, usually due to prolonged immobility. Sitting for several hours in cramped conditions can reduce circulation in your legs, allowing blood to pool and potentially clot.
Air travel poses an additional challenge because cabin pressure and dehydration may further increase the risk of clotting, including deep vein thrombosis (DVT).
Certain individuals face a higher likelihood of developing DVT during travel. Risk factors include:
Patients with heart disease or vascular conditions should also exercise added caution during long trips.
Blood clots, especially DVTs, can quickly escalate into serious cardiovascular emergencies, including pulmonary embolism (PE). However, early awareness and proactive measures can make a significant difference.
Understanding the symptoms of DVT and pulmonary embolism is crucial for travelers. Deep vein thrombosis often causes swelling, pain, warmth, tenderness, or redness in one leg, usually in your calf. Symptoms may appear during travel or even several days after returning home.
If part of the clot breaks free and travels to your lungs, it can result in a PE. Warning signs include sudden shortness of breath, chest pain, rapid heartbeat, dizziness, or coughing up blood. A PE requires immediate emergency medical attention.
Travelers should never ignore persistent leg swelling or discomfort, or unexplained breathing difficulties, during or after a long journey. Prompt diagnosis and treatment can prevent severe complications.
The good news is that most travel-related blood clots are preventable. Our team recommends these practical steps that support healthy circulation during long trips:
Movement is one of the most effective ways to reduce the risk of clotting. Travelers should stand up, stretch, and walk every one to two hours whenever possible. On airplanes, walking the aisle periodically can help maintain blood flow.
If standing is not feasible, seated exercises can improve circulation. Flexing and extending the ankles, rotating the feet, and tightening the calf muscles several times each hour encourages blood flow through the veins.
Dehydration can thicken the blood and contribute to clot formation. Drinking plenty of water before and during travel helps maintain healthy circulation.
Limit alcohol and excessive caffeine intake because both can increase dehydration since they act as diuretics. Carrying a reusable water bottle is a simple but effective habit for long summer trips.
Graduated compression stockings gently improve blood flow in the legs and may lower the risk of DVT in higher-risk individuals. These stockings are particularly beneficial for travelers with a prior history of blood clots or chronic venous disease.
We recommend consulting with your physician before travel to determine whether compression therapy is appropriate for your medical history.
Interventional cardiologists sometimes recommend anticoagulants for individuals with a high risk of clot formation. However, medication decisions should always be individualized. Travelers should speak with their provider well before departure to discuss safe preventive options.
Summer vacations should create lasting memories, not unexpected medical emergencies. Schedule a visit at Premier Cardiology Consultants today for a pre-travel checkup.
