Sitting still for hours in a cramped position, combined with lower cabin pressure and limited movement, slows blood flow in the leg veins and allows blood to pool, which makes it easier for clots to form. Risk factors include flights of more than four hours, sitting in a window seat, taking several flights in one journey, dehydration, smoking, alcohol, use of oral contraceptives and any pre-existing blood clotting condition. According to a World Health Organisation report covered by the British Medical Journal, the risk of venous thromboembolism doubles after long haul air travel of more than four hours’ duration, and the risk increases with the duration of the travel and with multiple flights within a short period. For healthy travellers, the overall risk remains low. The report put the absolute risk among healthy individuals for a flight of more than four hours at 1 in 6000. The risk is considerably higher for people with additional risk factors.<\/p>

Most flight-related clots can be prevented with simple habits. Walk up and down the aisle every hour or two when it is safe to do so. When seated, flex and point your ankles regularly to keep the calf muscles pumping blood back towards the heart. Drink plenty of water, limit alcohol and caffeine, and avoid sleeping for long stretches in a cramped position. If you choose your seat, an aisle seat makes moving around easier. Well-fitted graduated compression stockings can also help, particularly for travellers with additional risk factors. If you have had a blood clot before, have a clotting disorder, or have recently had surgery, see a vascular specialist before a long-haul trip. After landing, seek medical attention promptly if you develop swelling, pain, warmth or redness in one leg, or sudden breathlessness or chest pain. These can be signs of deep vein thrombosis or pulmonary embolism.<\/p>

Anticoagulants, or blood thinners, are vital in \u6df1\u9759\u8109\u8840\u6813\u6cbb\u7597<\/a>. They prevent existing clots from enlarging and reduce the risk of new clots by inhibiting clotting factors. Though they don\u2019t dissolve clots directly, they aid the body\u2019s natural clot breakdown process. They help manage DVT and prevent complications like pulmonary embolism and post-thrombotic syndrome, which can lead to heavy and swollen limbs.<\/p>
