Evidence has shown that deep vein thrombosis, DVT, may occur during a long-haul flight. It is associated with prolonged periods of cramped mobility and is more inclined to occur in elderly or obese people, or in women taking oral contraceptive pills. Nevertheless, it may also occur in young and apparently healthy individuals.
The condition is unlikely to occur on flights into and out of Ireland as the vast majority are of less than five hours duration. However, more and more Irish people are undertaking long haul flights and on these flights the effects of prolonged immobilisation, dehydration and different atmospheric pressure can all contribute to cause DVT.
While I am aware of the recent reports concerning this condition, I have no immediate plans to initiate an awareness campaign. However, Aer Lingus has made recommendations for passengers in its in-flight magazine, with suggestions for in-flight leg exercises and a good fluid intake to combat dehydration. I welcome initiatives such as this and will keep the matter under review to determine if any action is required.
