Ask anyone, “What’s the greatest medical risk of dying?” and they’ll answer “Heart attack.” The correct answer is a blood clot (Thrombosis) that occurs in the heart, brain or legs. Now, a shocking report in the health publication, “LifeExtension”, shows what can happen to our legs when we’re flying at 35,000 feet. So with an aging population, and increased air travel, what can be done to decrease the risk of a blood clot?
Thrombosis can happen anytime and anywhere. But the greatest risk is a long air flight. This is when venous blood pools in the lower leg due to inactivity. But the extent of this threat has surprised researchers. Using ultrasound imaging they detected venous thrombosis in the lower legs in 5 to 7 percent of passengers, whose flights lasted 7 to 8 hours. But without symptoms, passengers were totally unaware of the presence of the thrombosis, or that it could kill them!
