blood clots after long plane flights
There's new concern about blood clots after long plane flights. It's often called "economy class syndrome."
This has always been a concern for people with a history of venous thromboembolism...obesity...recent major surgery...or old age.
Now there's growing concern for women who take oral contraceptives. Their risk of thrombosis from long plane flights can be 14 times higher than women not taking OCs.
