Definition & Meaning of "thrombosis"

What is "thrombosis"?

Thrombosis is a medical condition where a blood clot forms inside a blood vessel, blocking blood flow. This clot, called a thrombus, can develop in arteries or veins throughout the body and may lead to serious complications if it travels to other parts of the body, causing an embolism. Thrombosis can occur because of factors such as injury to blood vessels, prolonged immobility, certain medical conditions, or genetic factors that affect blood clotting. Symptoms depend on the location of the clot and may include pain, swelling, warmth, or redness in the affected area. Treatment typically involves blood-thinning medications to prevent the clot from getting larger and to reduce the risk of further clots forming.
