If the water pipes are blocked, the water quality will be poor; if the roads are blocked, the traffic will be paralyzed; if the blood vessels are blocked, the body will be damaged. Thrombosis is the main culprit of blood vessel blockage. It is like a ghost wandering in the blood vessel, threatening people's health at any time.

A thrombus is colloquially referred to as a "blood clot", which blocks the passages of blood vessels in various parts of the body like a plug, resulting in no blood supply to the related organs and sudden death. When a blood clot occurs in the brain, it can lead to cerebral infarction, when it occurs in the coronary arteries, it can lead to myocardial infarction, and when it is blocked in the lungs, it is a pulmonary embolism. Why do blood clots occur in the body? The most direct reason is the existence of coagulation system and anticoagulation system in human blood. Under normal circumstances, the two maintain a dynamic balance to ensure the normal flow of blood in the blood vessels without thrombus formation. However, under special circumstances, such as slow blood flow, coagulation factor lesions, and vascular damage, it will lead to hypercoagulation or weakened anticoagulation function, and the relationship is broken, and it will be in a "prone state".

In clinical practice, doctors are used to classify thrombosis into arterial thrombosis, venous thrombosis, and cardiac thrombosis. Also, they all have internal passages that they like to block.

Venous thrombosis loves to block the lungs. Venous thrombosis is also known as the "silent killer". Many of its formations have no symptoms and feelings, and once it occurs, it is likely to be fatal. Venous thrombosis mainly loves to block in the lungs, and a common disease is pulmonary embolism caused by deep vein thrombosis in the lower extremities.

Arterial thrombosis loves to block the heart. Arterial thrombosis is very dangerous, and the most common site is the heart blood vessels, which can lead to coronary heart disease. Arterial thrombus blocks the main large blood vessels of the human body - coronary arteries, resulting in no blood supply to tissues and organs, causing myocardial infarction or cerebral infarction.

Heart thrombosis loves to block the brain. Patients with atrial fibrillation are most prone to heart thrombus, because the normal systolic motion of the atrium disappears, resulting in the formation of thrombus in the cardiac cavity, especially when the left atrial thrombus falls off, it is most likely to block the cerebral blood vessels and cause cerebral embolism.

Before the onset of thrombosis, it is extremely hidden, and most of the onset occurs in quiet conditions, and the symptoms are severe after the onset. Therefore, active prevention is very important. Exercise more every day, avoid staying in one position for a long time, and eat more fruits and vegetables. Finally, it is recommended that some high-risk groups of thrombosis, such as middle-aged and elderly people or those who have undergone surgical operations or have suffered blood vessel damage, go to the thrombus and anticoagulation clinic of the hospital or a cardiovascular specialist for a screening of abnormal blood clotting factors related to thrombus, and regularly detect With or without thrombosis.
