What is a recommended method to prevent travel-associated deep vein thrombosis (DVT)?

Frequent ambulation is a key strategy for preventing travel-associated deep vein thrombosis (DVT). When individuals are traveling, especially during long flights or extended periods of sitting, blood flow in the legs can become sluggish due to inactivity. This can increase the risk of clot formation in the deep veins. Regular movement or walking allows for better circulation, which can help reduce the likelihood of clot development.

Inactivity leads to stasis of blood flow, which is a major factor in the formation of DVT. Taking periodic walks or even simple leg exercises while seated can significantly improve venous blood return and help mitigate this risk. This recommendation is particularly important for travelers who are on long journeys where movement is limited.

Other options, such as increased alcohol intake, do not have a beneficial effect and can actually contribute to dehydration, which may increase the risk of clot formation. Smoking cessation is important for overall health and reduces the risk of cardiovascular disease, but it is not specifically a preventive measure for DVT in the context of travel. A high salt diet can lead to fluid retention and potentially increase blood pressure, which also does not directly address the prevention of DVT. Overall, the best approach to mitigate the risk of DVT during travel remains frequent ambulation
