What Is Thrombosis?
Thrombosis happens when blood turns into clumps inside a blood vessel, creating what is known as a thrombus or a blood clot. At times, these clumps can form inside the heart. This blocks the flow of blood in the vessel where the clot is. Thrombosis can happen in veins and arteries, and one or several clots might block the flow. It most often occurs in the blood vessels of the legs.
