Deep Vein Thrombosis (DVT) is a medical condition where a blood clot forms in a deep vein, usually in the legs. This can cause swelling, pain, and redness in the affected area. DVT can occur due to prolonged immobility, certain medical conditions, or injury to the veins. If a clot breaks loose, it can travel to the lungs, leading to a serious condition called Pulmonary Embolism. Risk factors for DVT include surgery, obesity, and smoking. Early diagnosis and treatment are essential to prevent complications and improve outcomes.
