In the category of atherosclerotic diseases. When the arterial blockage exceeds 75%, the blood flow is too small, which will cause discomfort such as chest tightness, shortness of breath, dizziness and headache. Even if the blood vessels are only blocked by 20%~50%, atherosclerotic plaques will sometimes rupture to form thrombus, which will lead to stroke, myocardial infarction and even life-threatening. So people often say that "the life span of blood vessels determines the life span of people." Big fish and big meat, smoking, eating too much salt or sugar, staying up late and lack of exercise are all culprits that hurt blood vessels, making them brittle and hard, forming blood clots and blocking them.
To protect the health of blood vessels, we should check blood vessels regularly, eat less foods with high oil, salt and sugar, and eat more foods (such as hawthorn, oats, auricularia auricula, onions, etc. ) Clean up vascular garbage, sit less and exercise more, and drink 7 to 8 glasses of water every day to prevent blood from thickening. It is best to get up in the morning and drink it one hour before meals.
Vascular blockage can cause ischemic infarction of important organs and tissues. Common myocardial infarction and cerebral infarction are caused by coronary artery and head and neck artery blockage, which not only seriously affects organ function, but also has a certain risk of death. So, which part of the body is more likely to block blood vessels? How to prevent it? Next, medical science will analyze it for you.
Our body has a complex and perfect vascular system, which mainly undertakes the functions of blood transportation, oxygen supply and energy supply. Blood starts from the heart, reaches the capillaries through arteries, supplies the oxygen it carries to organs and tissues, then reaches the lung tissue through veins, and returns to the heart with oxygen-enriched blood, so as to ensure the normal operation of various physiological activities. Vascular patency is an important guarantee for normal physiological activities, but many diseases will cause vascular blockage, local thrombosis of blood vessels will cause vascular blockage, and thrombi falling from other parts will also cause blockage when they flow to blood vessels with the same diameter as thrombi. When fracture, adipose tissue burn or severe contusion, fatty liver is violently squeezed or hit, and fat cells rupture to release fat droplets, which will also cause blood vessel blockage; A large amount of air enters the blood, or the air in the blood freely forms bubbles, which will also block blood vessels; During childbirth, amniotic fluid enters the blood through the ruptured blood vessels in the uterine wall, which can also cause vascular embolism. Among them, the most common cause is thrombosis.
Under normal circumstances, the body's coagulation and anticoagulation systems are in a state of balance, which can prevent thrombosis, but when this balance is broken, thrombosis can be formed. Smoking, hypertension, diabetes and other diseases can damage the intima of blood vessels, and transport low-density lipoprotein cholesterol to the intima of blood vessels, which on the one hand causes atherosclerosis, on the other hand destroys the integrity of the intima of blood vessels, exposes the collagen under the intima, and releases tissue factors into the blood to start the coagulation system to form thrombus. Thrombosis caused by this mechanism usually occurs in arterial system. Patients with long-term illness, heart failure, etc. There is slow blood flow or vortex, which increases the contact and adhesion between platelets and arterial intima, and can also form thrombus. Thrombosis caused by this mechanism usually occurs in venous system, such as popliteal vein and femoral vein. Because tumor cells release more procoagulant factors, tumor patients can increase blood coagulation and form thrombus. Among them, the most common diseases are thrombosis caused by atherosclerosis and plaque rupture.
Atherosclerosis will harden the arterial lumen and reduce its elasticity. The most important change is lumen stenosis, which reduces the blood supply of important organs and leads to ischemia and even infarction. At the same time, after the formation of plaque secondary to atherosclerosis, the rupture of plaque induces thrombosis, and blocking vascular lumen can also cause organ ischemic infarction. But the probability of involvement of different arteries is different. The main arterial systems such as aorta and carotid artery and the intermediate arterial systems such as coronary artery and cerebral artery are most affected, while the probability of pathological changes in other arterial systems is relatively low or the degree of pathological changes is relatively low.
It can be seen that once severe vascular stenosis caused by atherosclerosis or vascular blockage caused by rupture of arterial plaque occurs, the consequences are quite serious. Once there are brain cells and myocardial cells sensitive to ischemia, even after reasonable treatment, their functions can not completely return to normal. Therefore, these vascular diseases need early prevention to reduce the risk of vascular blockage:
To sum up, vascular obstruction can be caused by many reasons, such as thrombosis or thromboembolism, fat embolism, air embolism and amniotic fluid embolism. , can cause vascular obstruction, especially thrombosis or thromboembolism; Vascular blockage caused by thrombosis can be caused by plaque rupture, slow blood flow, vortex and increased blood coagulation caused by atherosclerosis. Among them, atherosclerosis and plaque formation are the main causes of vascular occlusion, mainly involving middle arteries such as aorta and carotid artery, such as cerebral artery and coronary artery. These blood vessels have different degrees of stenosis and cause different symptoms. If the arterial lumen is severely narrowed or occluded, it can cause acute cardiovascular events such as myocardial infarction and cerebral infarction. In prevention, we should change our lifestyle, give priority to a diet with low salt, low fat, low cholesterol and low sugar, exercise properly, quit smoking and limit alcohol. Can prevent or alleviate vascular injury; If there are cardiovascular risk factors such as hypertension, diabetes and dyslipidemia, rational medication on the basis of lifestyle intervention can reduce vascular damage; If vascular injury has occurred, statins and antiplatelet aggregation drugs should be used reasonably to reduce the risk of vascular occlusion and interventional therapy if necessary.

Hello, let me answer this question! Vascular blockage is the result of many factors, among which the deposition of "garbage" in blood vessels and the main factor of plaque formation period, which is often referred to as atherosclerosis, are the basis of vascular blockage and the main cause of many cardiovascular and cerebrovascular diseases.
When the blood vessels are blocked, the patient will be out of breath with a little activity. A little activity will lead to frequent panting, rapid heartbeat and dizziness. Be alert for blood vessel blockage.
The accumulation of venous blood vessels caused by varicose veins can cause chronic skin ulcers. At this stage, the skin will be in an ischemic state, from pink to dark purple, gangrene or ulcer will appear locally, and it will also spread to surrounding tissues.
Cervical vascular occlusion is also called carotid stenosis. Its pathological basis is carotid atherosclerosis or other diseases, which narrows the cross section of carotid canal's cavity and directly reduces blood supply to the brain. If the carotid artery is completely blocked, it is called carotid artery occlusion, which will greatly increase the risk of stroke. To some extent, cervical vascular occlusion is the early stage of cerebral infarction, stroke and other diseases, which needs to be paid enough attention.
For prevention, we must first improve our lifestyle, adhere to proper regular exercise, adhere to a balanced diet, adhere to the treatment of cardiovascular diseases such as hypertension and diabetes, control our weight at a relatively stable level, and maintain a good attitude.
Protecting blood vessels is a very important thing. The temperature difference between morning and evening in autumn and winter is very large, which is easy to cause blood vessel blockage. At the same time, the environment is relatively cold, the amount of human activity is also reduced, the blood flow is relatively slow, and the blood viscosity is also increased. Under the influence of these factors, blood vessels are easily blocked.
Blood vessels are like roads in our lives. If it is blocked, many problems will occur, leading to many diseases, which will have a great impact on the human body and even lead to life-threatening. The occurrence of vascular occlusion is getting younger and younger, which has a lot to do with the lifestyle and diet of young people. Faced with this disease, how can we prevent it?
The methods to prevent blood vessel blockage are as follows
1, toe
Toe toe has a certain effect on preventing blood vessel blockage. Lift your heel, hold it for five seconds, and then put it down. Insisting on exercise can make people's calf muscles contract regularly, stimulate blood vessels, greatly increase the blood flow speed of lower limbs, and prevent blood vessel blockage well.
2, a reasonable diet
In daily life, we should pay attention to nutrition and maintain a balanced nutrition. We can eat more foods that can clean blood vessels, such as tomatoes and onions. These foods can not only provide nutrients needed by human body, but also clean blood vessels, thus preventing the occurrence of blood vessel blockage.
3, the right amount of tea and red wine
Tea contains tea polyphenols, which can reduce the content of cholesterol in blood, increase the elasticity of blood vessels and prevent blood vessels from clogging. Red wine has antioxidant effect, softens blood vessels and prevents blood vessel blockage.
4. Appropriate physical exercise.
Proper exercise at ordinary times helps to reduce the body's fat and cholesterol, promote the decomposition of garbage in blood vessels, thus preventing the blockage of blood vessels, and at the same time preventing the formation of blood clots, making the blood circulation system in the body healthier.
The above four points are the methods to prevent blood vessel blockage. Although it is rare, it is very practical. Regular exercise and more exercise can regulate the nervous system of the body, dilate blood vessels and promote blood circulation. At the same time, we should get rid of some bad living habits, pay attention to rest and don't stay up late, which will lead to vasoconstriction, slow blood flow and increase blood viscosity.
Our blood vessels are like roads in the human body. The starting point of the road is the aorta of the left ventricle of the heart. Aorta is the largest arterial tube in human body, which is equivalent to the "highway" in our body. After the aorta originates from the heart, it first arches upward into an arch (we call it the aortic arch) and then descends along the spine. In the thoracic cavity and abdominal cavity, they are called thoracic aorta and abdominal aorta respectively, and there are many branches along the way. Branches then branch into smaller branches ..... The closer to tissue cells, the smaller the branches, and finally become capillaries. Tissue cells exchange substances with blood through capillaries. Waste products such as carbon dioxide produced by cell metabolism penetrate into blood through capillary wall, and nutrients such as oxygen in blood penetrate into cells through capillary wall. The flowing blood transports these wastes to organs such as lungs and kidneys and finally excretes them, and continuously delivers fresh nutrients to tissues and cells.
There are few traffic jams on expressways. Unless there are special festivals such as holidays, the smaller the expressway, the easier it is to get stuck in traffic. The blood vessels in our bodies are the same. The most easily blocked blood vessels are often small blood vessels far from the aorta. The smaller the blood vessel, the easier it is to block. Next, I will give you an inventory of several places where blood vessels are easily blocked and the consequences are particularly serious. The blockage of blood vessels in the above two parts of the body is a common and very serious situation in clinic. The main cause of arterial obstruction is atherosclerosis. After atherosclerosis, the inner wall of blood vessels will become no longer smooth, and some "impurities" in blood will attach to the rough inner wall. With the passage of time, "impurities" will accumulate more and more, eventually causing blood vessel blockage. Someone once said that "people's life span is the same as that of arteries", which means that the arteries of the human body are constantly hardened and blocked, and the day when the heart, brain and other important organs are finally infarcted is the end of life. Therefore, if a person wants to live long, he must first ensure that blood vessels can be used for several years.
So, how can we keep blood vessels unobstructed and avoid blood vessel blockage? The subject's question is a good question, which is one of the reasons why many cardiovascular and cerebrovascular diseases are prone to occur at present. Before answering the subject's question, we should know that blood vessels are all over the body and belong to the circulatory system of the human body, so it is necessary for us to know about our circulatory system. The circulatory system is divided into arteries and veins. Arteries and veins are connected with the heart, and the heart injects blood into the arteries, and then the arteries are distributed to various organs and limbs of the human body from coarse to fine, becoming capillaries, and finally the capillaries converge to veins, and the veins return to the heart from fine to coarse, forming a closed loop.
So the heart is the thickest, and the capillaries at the ends of organs and limbs are the thinnest, just like rivers in nature. A big river often has many streams that slowly converge into a larger and larger river, and finally the river flow is the largest at the estuary.
Then we saw the river flowing on the river bed and the blood flowing in the blood vessels. This is one thing. Where are the natural rivers most easily blocked? Of course, it is the smallest and slowest stream on the river bed, and so are the blood vessels in our bodies. The capillaries at the ends of various organs and limbs are the most easily blocked. Why are they called capillaries? Because these blood vessels are thin, as thin as hair, but actually thinner than hair, the diameter of capillaries is only 8- 10 micron, and only red blood cells are allowed to pass through in a single file.
Therefore, the capillaries are very thin, and the capillaries of organs are most easily blocked! Why? Because our limbs such as hands and feet are walking around, moving around and moving around every day, it is these activities that make the blood of hands and feet flow more easily in capillaries, so instead, the capillaries of various internal organs are more likely to be blocked. Among these organs, the capillaries of the brain and the capillaries of the heart are the most easily blocked.
Why? Because the most important organs of the human body are the heart and brain, one death is cardiac arrest and the other is brain death, which is the standard for judging death. Therefore, in all organs of the human body, the heart and brain are the most important. The human body has an automatic adjustment function, that is, where blood is most needed, the blood will be delivered first. Therefore, the blood vessels in these places are also the places with the greatest pressure and the places where capillaries are most easily damaged, which is the same as the two asphalt roads.
So the same capillary, damaged, is more likely to lead to poor blood flow and blockage, which is like the same traffic flow. It is a truth that the damaged road is more likely to be blocked. Therefore, the capillaries in the heart and brain are more likely to be blocked, which is also a common cause of cerebral blood supply deficiency and myocardial blood supply deficiency in clinic, as well as a common cause of cerebral infarction and myocardial infarction. The so-called infarction is that the lumen of a blood vessel is blocked and blood cannot pass through, then the cells supplied by this blood vessel will starve to death. The hunger of brain cells is called cerebral infarction, and the hunger of myocardial cells is called myocardial infarction.
Above, we know the place where capillaries are most easily blocked. Besides blood vessels, there is also blood flowing in them. The thicker the blood, the easier it is to be blocked, which is related to the more cars on the road, and the more silt mixed in the river, the easier it is to be blocked. This is a fact. What is the viscosity of blood related to?
In addition to cells, there are blood lipids, blood sugar, uric acid and so on. The increase of these components will inevitably lead to the viscosity of blood. These things are like mixed sediment, leaves, branches and so on. In the river, just like bicycles and motorcycles are added to the traffic on the road, they are inseparable. Therefore, if we want to solve the problem of hyperlipidemia, hyperglycemia and uric acid from the root, so as to reduce the blood lipid, blood sugar and uric acid, on the one hand, drug treatment is to change the living habits, especially the diet structure, light diet, less meat and vegetables, less oil and less salt, because the food we eat is transformed in the body, so it is very important to manage our mouth!
Chinese medicine is promoting blood circulation and removing blood stasis, because these increase the viscosity of blood, which will inevitably lead to congestion. Knowing this, you will naturally know how to prevent it! To sum up: first, keep your mouth shut; Second, it is necessary to prescribe the right medicine to reduce blood sugar, blood lipid and uric acid; Third, we should promote blood circulation and remove blood stasis. How to take medicine and go to the local hospital to see a doctor face to face is more targeted!
