Deep Vein Thrombosis (DVT) occurs when a blood clot forms, often in the lower leg, which in some cases can be exacerbated by sitting still for long periods of time. For this reason, DVT is sometimes incorrectly referred to as Economy Class Syndrome.
Although the risk of developing DVT is rare, it can be a serious and sometimes fatal condition and you should consult your doctor before travelling if you have any concerns, especially if you fall into a high risk group.
Who Is At Risk?
• Those with a history of thrombosis
• Pregnant women
• Women who are taking an oral contraceptive pill
• Obese people
• Some patients with congestive heart failure
• People with maligant disease
To Reduce Your Risk
• Seek expert medical advise before you fly, if you are considered to be particularly at risk
• Avoid becoming dehydrated, so drink plenty of water
• Limit the amount of alcohol and caffeine you consume during the flight
• Avoid smoking before the flight
• Make sure you are wearing comfortable and loose fitted clothing
• Walk around the cabin during the flight
• Do not cross your legs
• Wear elastic stockings
• Pack any prescription medication in your hand luggage and take it as prescribed
