What is a common risk factor for developing deep vein thrombosis (DVT)?

Prolonged immobility is widely recognized as a significant risk factor for developing deep vein thrombosis (DVT) due to the stagnation of blood flow in the venous system. When an individual is immobile for extended periods—such as during long flights, bed rest following surgery, or serious illness—blood in the veins, particularly in the lower extremities, can pool and begin to clot. This condition offers a conducive environment for thrombus formation, leading to DVT.

In contrast, excessive physical activity typically promotes healthy circulation and decreases the risk of clot formation, while frequent hydration helps to maintain proper blood viscosity and flow. Low cholesterol levels are generally associated with a lower risk of cardiovascular diseases, but they do not directly influence the likelihood of developing a DVT. Therefore, the connection between immobilization and DVT underscores the importance of movement and circulation in the prevention of this condition.
