Can Flights Cause DVT When On Vacations And Holidays?

People who take air flights when they travel on their vacations and holidays can be at risk of developing a serious medical condition called deep vein thrombosis, or DVT, which can be life threatening. The following article covers travel tips on how you can prevent this potential problem from developing into a serious medical condition when you travel on airline flights.

Commercial air flights tend to cause airline passengers’ blood to get thicker and slow down which can increase the possibility of blood clots, particularly in the lower extremities. And, the longer the flight, the greater the risk. Deep vein thrombosis, or DVT, is caused by a blood clot forming in one of the legs. This is a medical emergency. If this dangerous clot breaks away, it may move to the lungs which then could be fatal.

A common misconception is that younger, stronger, and physically fit athletes are less likely to develop deep vein thrombosis. Recent research shows that many people with a slower at rest blood flow, such as athletes, are in reality more at risk than the general population. People that have a history of swollen legs can also be at risk. Other people who are at risk are those that have, or have had, a serious health condition such as heart disease, diabetes, or cancer. Women that are pregnant, or on birth control pills or on hormone replacement therapy, tend to be more prone to deep vein thrombosis. Obesity may also be a factor.

There are two sets of symptoms that relate to deep vein thrombosis that you should be aware of. The milder set of symptoms may start to show during your flight or within the next few days. These symptoms are tenderness, redness, swelling, or cramps in one of your lower legs. Some bruising or swelling can also appear behind one of your knees. The most severe second set of symptoms generally appear two or more days after a blood clot has been formed. These symptoms can include fainting, shortness of breath, painful or rapid breathing, chest pains that can be accompanied by pain in one shoulder, coughing up blood, and fever.

What can contribute to these dangerous symptoms?

Deep vein thrombosis can occur in your lower legs anytime you are sitting in one position for a long time without moving your legs and feet. Some research shows that you are at three times the risk of developing this very serious medical condition when you fly. Driving, traveling by bus or train, or even sitting in your favorite easy chair at home can also cause it.

How can you, as an airline passenger, prevent this life-threatening condition from happening?

You can help prevent DVT from developing in your legs by increasing your circulation. If you are predisposed to any of the risks above, you may want to book an aisle seat to give you some more room to move and enable you to get up and walk around at anytime without disturbing other passengers.

Some experts suggest you wear loose clothing and avoid wearing tightly fitting slacks and elastic support stockings or socks; move and exercise your legs frequently while sitting; change your sitting position often; not sitting with you legs crossed; walk up and down the aisle every half-hour or so, and drink a sports drink such as Gatorade so you do not become dehydrated.

It’s very common for deep vein thrombosis to be misdiagnosed which could then be fatal. If you develop any of the above symptoms you must seek medical help as soon as possible. Inform the physician who is treating you that you have recently flown and you think that it may be a blood clot. If the doctor doesn’t believe it is deep vein thrombosis, ask him to order an ultrasound of your leg to be sure. If you are experiencing chest problems insist that a simple and painless blood oxygen measurement on your finger be done. It only takes a couple of minutes and will help to prevent a serious misdiagnosis of your condition.
