Can blood clots in lungs be caused by drinking?

Blood clots in the lungs, known as pulmonary embolisms, are primarily caused by deep vein thrombosis (DVT) and not directly by drinking alcohol. However, excessive alcohol consumption can increase the risk of clot formation by promoting dehydration, which thickens the blood, and by impairing liver function, which affects clotting factors. Additionally, heavy drinking may lead to behaviors that increase the risk of DVT, such as prolonged immobility. Moderation is key to reducing these risks.
