Which factor is least likely to contribute to the development of a DVT?

Regular physical activity is least likely to contribute to the development of a deep vein thrombosis (DVT). In fact, engaging in regular exercise and maintaining an active lifestyle are known to promote healthy blood circulation and can significantly reduce the risk of blood clots forming in the veins. Physical activity enhances venous return and can help prevent the stasis of blood that often leads to the development of DVT.

On the other hand, factors such as recent surgery, prolonged immobilization, and smoking are recognized risk factors for DVT. Surgery can lead to reduced mobility and may involve trauma to the blood vessels, while prolonged immobilization can cause blood to pool in the veins. Smoking is associated with changes in blood coagulation properties, contributing to an increased risk of clot formation.
