A deep vein thrombosis (DVT) is a blood clot (thrombus) that develops in a deep vein, usually in the leg. This can happen if the vein is damaged or if the flow of blood slows down or stops. Deep vein thrombosis can cause pain in the leg, and can lead to complications if it breaks off and travels in the bloodstream to the lungs.
IT IS now recognised that long periods of inactivity, combined with the cramped conditions and dehydration which can occur on long journeys, can cause a number of circulatory problems, ranging from swollen ankles and tired aching legs to more serious conditions such as deep vein thrombosis (DVT).
One in 20 people could be affected by flight-induced blood clots.
Contributing factors:
- Cramped conditions that many passengers may encounter during flights
- Low humidity
- Reduced cabin pressure
- Dehydration
Those at high-risk include:
- people with previous history of Venous Thrombosis (Blood Clots) and Pulmonary Embolism
- age above 40 (risk increases with age)
- pregnant women
- those who use oral contraceptives or hormone replacement therapy (HRT)
- those who had recent surgery or injury, especially to lower limbs/abdomen
- those with cancer and undergoing treatments, which can cause blood to clot more easily
- those with genetic blood clotting abnormalities (eg. Factor V Leiden)
Prevention is the best therapy
Helpful Tips:
- Don’t take sleeping pills
- Wear loose-fitting clothes
- Keep legs uncrossed
- Drink water regularly
- Avoid alcohol as much as possible
- Wear compression socks
