Blood coagulation known as a blood clot is what prevents excessive bleeding when we suffer injury. The body naturally absorbs the clotting after healing. However, clots that form without any injury are a medical condition that needs urgent attention. Blood clot or deep vein thrombosis (DVT) occurs when a blood clot forms in one of the deep veins of the body, usually in the legs and arms.

There are certain risk factors like heredity and age, but the leading cause of DVT is sitting or lying in a position for a long time, such as surgery and long flights or long rides.
