Commercial air flights 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 relating to deep vein thrombosis that you must be aware of. The first set of milder symptoms may start during your flight or in the following couple of days. These symptoms are swelling, redness, tenderness, or cramps in one of your lower legs. There also can be some swelling or bruising behind one of your knees. The more severe second set of symptoms usually appear two or more days after the blood clot has formed. They are shortness of breath, rapid or painful breathing, fainting, a fever, chest pain which may be accompanied by pain in a shoulder, and coughing up blood.
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 deep vein thrombosis, or DVT, from developing by increasing circulation in your legs. If you are predisposed to any of the above risks you may want to book an aisle seat to give you more room to move and allow you to get up and walk around anytime without disturbing the other passengers.
Many experts suggest that when you fly you should wear loose clothing and avoid wearing tight fitting slacks or pants, as well as elastic support socks or stockings; moving and exercising your legs frequently while sitting; changing your sitting position often; not sitting with you legs crossed; walking up and down the aisle every half-hour or so, and drinking a sports drink such as Gatorade so you do not become dehydrated.
Its 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 doesnt 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.
