First Flight - Prevent Deep Vein Thrombosis When On Vacation
June 14th, 2009
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 misunderstanding is that young, strong, physically fit athletes are less likely to develop deep vein thrombosis. Scientific research indicates that many people with a slower at rest blood flow, like athletes, are actually more at risk than the general population. A person who has a history of swollen legs can also be more at risk. Other people at risk are those that have, or have had, a serious medical condition such as diabetes, heart disease, or cancer. And, women that are pregnant, or on birth control pills or hormone replacement therapy, tend to be more prone to DVT. Being overweight can also be a factor.
There are actually two sets of symptoms pertaining to deep vein thrombosis that you should be aware of. The first milder set of symptoms may appear during your flight or within the following couple of days. These symptoms are redness, swelling, tenderness, or cramps in one of your lower legs, or some swelling or bruising behind one of your knees. The second set of symptoms are more severe and usually appear within two or more days after a blood clot has formed. They are fainting, shortness of breath, rapid or painful breathing, chest pain which can be accompanied by pain in the shoulder, coughing up blood, and a fever.
What can contribute to these serious symptoms?
Deep vein thrombosis can occur in your lower legs at anytime when you are sitting in one position for a long period of time without moving. Some research shows that you are at three times the risk of developing this serious medical condition when flying. Driving and traveling by bus or train, or even sitting in your favorite easy chair can also cause it.
As an airline passenger, how can you 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.
It is very common for deep vein thrombosis to be misdiagnosed which could be fatal. If you develop any of the above symptoms you must seek medical help immediately. Inform the doctor who is treating you that have just recently flown and you think that it could be a blood clot. If the physician doesnt believe it is deep vein thrombosis, ask him to order an ultrasound of your leg to be sure. If you are experiencing any chest problems, insist that he or she do a simple and painless blood oxygen measurement on your finger. It only takes a couple of minutes and will prevent a serious misdiagnosis of your condition.
