Deep Vein Thrombosis (DVT)
Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, most often in the legs. This can restrict blood flow and cause pain or swelling — and in some cases, the clot may travel to the lungs, leading to a serious condition known as a pulmonary embolism. Prompt diagnosis and treatment are essential to prevent complications and protect your vascular health.
