Why do we have blood clots in our bodies? Principles of preventing thrombosis

There is a coagulation system and an anticoagulation system in human blood. Under normal circumstances, the two maintain a dynamic balance to ensure normal blood flow in blood vessels and avoid formation of thrombus. However, under special circumstances, such as slowed blood flow, diseased coagulation factors, or damaged blood vessels, leading to hypercoagulation or weakened anticoagulant function, this balance will be broken, leaving the person in a "thromboprone state."

Some studies have shown that in spring, when the temperature fluctuates, the air pressure changes greatly, and the air is relatively dry, the blood viscosity in the body will increase. As the viscosity increases, the blood flow will slow down. Coupled with the relatively prolonged vasoconstriction time, some people, especially the elderly, have difficulty adapting to changes in environmental temperature due to vascular sclerosis or embolism, which can easily induce or aggravate cardiovascular and cerebrovascular diseases.

When the coronary arteries of the heart are embolized due to aggravation of arteriosclerosis or thrombus, and the blood flow is interrupted, resulting in local myocardial ischemic necrosis, it means that the human body has experienced acute myocardial infarction. Myocardial infarction is a common disease. Among Chinese men over the age of 60, the chance of suffering from this disease is as high as 13.2%.

Because blood clots are extremely hidden before the onset, and the symptoms are severe after the onset, and most of them occur in quiet situations, therefore, it is very important to actively prevent the onset of blood clots.

01

Healthy diet

If you are obese, you should limit the intake of staple food and control your weight; eat less or no animal fat and animal offal, such as Fatty meat, fat intestines, and tripe, because these foods contain high cholesterol and saturated fatty acids, can easily aggravate arteriosclerosis; eat appropriate amounts of high-quality protein, such as milk, duck, fish, eggs (eat less egg yolks), soy products, and less Eat pork, beef, and mutton, preferably lean meat; eat more foods rich in vitamins, such as fresh fruits, tomatoes, hawthorns, etc., which are rich in vitamin C; soy products, dairy, and eggs rich in vitamin B6; Green leafy vegetables, beans, etc. that are rich in vitamin E; the diet should be mainly light and avoid being too salty. It is best not to eat pickles, because eating too much salt can easily cause high blood pressure.

02

Appropriate physical labor and sports activities

Participating in certain physical labor and sports activities is beneficial to preventing obesity, exercising the function of the circulatory system and adjusting blood lipids. It is beneficial to metabolism and is an active measure to prevent this disease. Physical activities should be prescribed based on the original physical condition, original physical activity habits and heart function status, with the principle of not excessively increasing the burden on the heart and not causing discomfort. Physical activities can be carried out step by step, and strenuous activities should not be forced. For the elderly, it is recommended to take a walk (1 hour a day, in batches), do health gymnastics, Tai Chi, etc.
