What is a common risk factor for developing VTE?

Immobility is a well-established risk factor for developing venous thromboembolism (VTE). When a person remains immobile for an extended period, such as during long flights, bed rest after surgery, or due to certain medical conditions, the blood flow in the veins can become sluggish. This sluggish blood flow increases the likelihood of clot formation, particularly in the deep veins of the legs, leading to deep vein thrombosis (DVT) and potentially to pulmonary embolism if clots dislodge and travel to the lungs. Understanding the relationship between immobility and VTE is crucial for implementing preventive measures, especially in hospitalized or post-operative patients who may have limited mobility.

Regular exercise, low BMI, and high fluid intake are generally associated with a lower risk of VTE and promote better circulation, making them less likely contributors to this condition.
