Warning Signs Of Deep Vein Thrombosis

Coughing Up Blood

An individual affected by deep vein thrombosis may experience coughing up blood, sometimes called hemoptysis, as a symptom of their condition. Coughing up blood is a symptom that occurs when an individual incurs damage to the internal tissues of their lung. Millions of blood vessels line the lung and the small air sacs inside of them so oxygen and carbon dioxide exchange can occur. Individuals with deep vein thrombosis have blood clots form in the deep veins of one of their legs. When the blood clot breaks off of its original location and flows through the bloodstream and into the individual's lungs, it can cause the vessels it flows through in the lungs to become damaged. Damage can occur due to the passage of the clot itself, or due to an obstruction in the flow of blood to the lung tissues. The damaged blood vessels in the lungs leak blood, which accumulates in the branches of the lungs of which air uses to travel. The affected individual can start coughing this blood up because the blood obstructs the normal flow of air through the lung.
