Long Flights? Move to Prevent Blood Clots

Passengers embarking on long-haul flights this summer are advised to avoid remaining seated for extended periods to reduce the risk of deep vein thrombosis (DVT). DVT, a blood clot typically forming in the leg, can pose serious health risks. The danger escalates on journeys exceeding four hours due to slowed blood flow, potentially leading to a pulmonary embolism, a life-threatening condition.

While the risk is generally low for healthy travelers, certain individuals, such as those who have recently undergone surgery, are pregnant, have obesity, or a family history of clots, face a higher susceptibility. Symptoms to watch for include swelling, pain, warmth, or redness in a leg. More severe symptoms like sudden shortness of breath or chest pain necessitate immediate emergency medical attention.

Preventative measures recommended by health authorities include walking the cabin, wearing loose clothing, and drinking ample water. Simple seated exercises like bending legs and ankle rotations can maintain circulation. Avoiding alcohol before and during flights is also advised to prevent dehydration and encourage movement. Consulting a GP is recommended for high-risk individuals considering compression stockings.
