Q16. What is deep vein thrombosis?

A16. More commonly known as "DVT" this is where a blood clot forms in a vein which causes pain, inflammation and discomfort in the affected leg.

In serious cases it can lead to a condition called pulmonary embolism. This occurs when a piece of blood clot breaks away from the main blood clot and travels through the veins towards the heart.

If it becomes stuck within the veins to the lungs then it results in breathing difficulties, chest pain and collapse.

Deep vein thrombosis can occur if you sit for a long period of time without moving. One example of this is sitting in a confined area, e.g. a long haul flight.
