About: Deep Vein Thrombosis - DVT

Deep-Vein Thrombosis (DVT) is a common but serious medical condition that occurs in approximately two million Americans each year. DVT occurs when a thrombus (blood clot) forms in one of the large veins, usually in the lower limbs, leading to either partially or completely blocked circulation. The condition may result in health complications, such as a pulmonary embolism (PE) and even death if not diagnosed and treated effectively.

The best way to reduce your risk of DVT is to talk to your doctor about your risks, especially if you have cancer or certain heart or respiratory diseases.
