What risk factors increase the likelihood of developing deep vein thrombosis (DVT)?

Smoking and obesity
Recent surgery and prolonged immobilization
High cholesterol and diabetes
Frequent travel and dehydration

The correct answer is: Recent surgery and prolonged immobilization

The likelihood of developing deep vein thrombosis (DVT) is significantly increased by factors that promote stasis of blood flow, damage to blood vessels, and conditions that lead to hypercoagulability. Recent surgery and prolonged immobilization are critical risk factors. After surgery, particularly orthopedic procedures or those involving the pelvis or legs, the body experiences a period of limited mobility. This immobility can lead to stasis of blood flow in the lower extremities, which is a primary contributor to the development of DVT. Furthermore, surgical trauma can cause localized endothelial injury, increasing the risk of thrombus formation. Prolonged immobilization, such as long hospital stays or sedentary behavior during travel, also promotes blood pooling in the veins of the legs. These two factors together create a perfect environment for the development of DVT. The other options, while they may have some associations with vascular health, do not specifically encapsulate the acute and significant risk factors for DVT as closely as recent surgery and prolonged immobilization do.
