Deep Vein Thrombosis (DVT)

Deep vein thrombosis (thrombus means blood clot) is the condition where a blood clot forms in one of the deep veins, usually in a person's thigh or calf veins. The blood clot may either block the vein completely or partially.

It is more common in the elderly and the obese. Women are more prone to it.

DVT has gained prominence recently after headline reports of fatalities among long haul flight passengers. They have collapsed and died soon after disembarking their flights. Because of this coincidental relationship, DVT has been dubbed as economy class syndrome.

Deaths resulting from complications of DVT are not something new. Sporadic incidents have occurred in the past.

How do we prevent DVT? When you are on a Long Haul Flight:
- Try to avoid sitting in a cramped position for too long
- Wriggle your toes and move your ankles and knees
- Massage muscles of the lower limbs
- Don't cross your legs or sit on the edge of your seat
- Get up and walk along the aisle at least once an hour
- Wear loose clothing
- Avoid stockings or socks with tight bands
- Drink plenty of water
- Avoid alcohol
- Don't smoke
- Wear special support stockings designed for travelling

Other than that, try out the in-flight exercises on the right.
