The Risk of DVT During Long Flights: What You Need to Know

Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, typically in the legs. While DVT can occur for various reasons, long-duration flights are a common risk factor. Sitting for extended periods with little movement can increase the likelihood of developing a clot, which can travel to the lungs or cause serious complications. 

Understanding the risk of DVT during long flights and how to prevent it is necessary for any frequent traveler. Our doctors specializing in vascular disorders explain what you should know:

Why Long Flights Increase DVT Risk

During long flights, particularly those lasting four hours or more, passengers are often seated in cramped conditions. It can restrict their movement and circulation. The reduced blood flow in the legs can cause blood to pool, leading to the formation of clots. 

This is especially dangerous since the clot can break free, travel through the bloodstream, and lodge in the lungs. It can cause a pulmonary embolism, which can be life-threatening.

Who Is at Greater Risk?

While anyone can develop DVT, certain groups are more vulnerable. 

Older adults, pregnant women, and individuals with a history of clotting disorders or varicose veins are at increased risk. 

Other factors such as obesity, recent surgery, smoking, or taking birth control pills can also heighten the chances of developing a clot. 

Signs of DVT

It’s important to be aware of the symptoms of DVT, which can include swelling, pain, redness, or warmth in the affected leg. If you experience any of these symptoms after a flight, seek medical attention immediately. If left untreated, DVT can lead to serious complications, including a pulmonary embolism.
