People who are cooped up during extended periods of travel are at risk for a condition called deep vein thrombosis (DVT) and pulmonary embolism. This is a life-threatening condition that occurs when a blood clot forms in the leg and travels to the lungs.
Taking one or two regular (325 mg) aspirin a day or two before you go on an airplane flight, a train trip, or long car trip can prevent such a clot from forming.
A recent study found that aspirin might also prevent DVT and pulmonary embolism following hip surgery.
This study involved 770 hip replacement patients who all received the powerful intravenous blood thinner heparin for 10 days after surgery. Half of the patients then received heparin injections for four weeks while the other group took low-dose aspirin.
Of the heparin group, five people experienced a blood clot, but this occurred in only one person in the aspirin group.
In addition, five patients on heparin experienced serious bleeding, compared to only two in the aspirin group.
