Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in a deep vein [1]. These clots usually develop in the lower leg, thigh, or pelvis [2], and can cause pain and swelling in the affected area [4]. DVT is caused by damage to veins or slowed blood flow due to prolonged sitting or immobility [3][5][7]. It can also be caused by certain medications, pregnancy, cancer, smoking, obesity and other conditions. If left untreated it can lead to serious complications such as pulmonary embolism (PE), which is when part of the clot breaks off and travels through the bloodstream to the lungs [6][8][9][10].

Deep vein thrombosis (DVT) is a condition in which a blood clot forms in one of the deep veins of the body, usually in the legs. Symptoms may include pain, swelling, redness and warmth in the affected area. If left untreated, DVT can lead to serious complications such as pulmonary embolism or post-thrombotic syndrome. Treatment typically involves anticoagulant medications and lifestyle changes such as regular exercise and avoiding long periods of sitting or standing still.
