Thrombosis is the process of a blood clot, also known as a thrombus, forming in a blood vessel. This clot can block or obstruct blood flow in the affected area, as well as cause serious complications if the clot moves to a crucial part of the circulatory system, such as heart lung and brain.
A common complication of thrombosis is hypoxia, due to the obstruction of the artery of vein. When the majority of the blood vessel is blocked, the oxygen supply to the body is reduced and results in increased production of lactic acid.
Additionally, in some cases the blood clot may break free and travel around the body, a process known as embolization. This can obstruct the blood flow to essential organs, such as the brain or the lungs, reducing or inhibiting oxygen and blood flow with severe repercussions.
