What can cause a pulmonary embolism related to DVT?

A pulmonary embolism related to deep vein thrombosis (DVT) occurs when a blood clot that has formed in the deep veins, typically in the legs, breaks off and travels to the lungs. This can lead to a blockage in one or more pulmonary arteries, which is a serious and potentially life-threatening condition. The movement of the clot from one part of the body to another is the key mechanism behind the development of a pulmonary embolism.

In contrast, increased physical activity typically reduces the risk of DVT because it promotes better venous return and circulation. Hormonal changes can influence clot formation but are not a direct cause of a pulmonary embolism in the context of DVT. Excessive hydration can help prevent clot formation, as it maintains blood viscosity and circulation; therefore, it does not contribute to the risk of pulmonary embolism. Understanding the mechanics of how DVT can lead to pulmonary embolism emphasizes the importance of timely identification and management of DVT to prevent the progression to more serious complications.
