The main characteristic of superficial vein thrombosis is pain at the site of thrombosis, with the appearance of a reddened, hypothermic cord with tenderness and surrounding redness in the superficial vein. Thrombotic diseases include arterial thrombosis and venous thrombosis, arterial thrombosis is relatively more common, but venous thrombosis was once considered a rare disease and has not received sufficient attention. In fact, venous thrombosis is completely preventable and controllable. So let’s see how to prevent it in the end? 1, long-term immobility: the most likely to induce fatal thrombosis In the past, the medical profession believes that long-distance air travel and deep vein thrombosis is closely related, and the latest research found that sitting in front of the computer for a long time has also become a major cause of the disease, medical experts call this disease “electronic thrombosis”. Sitting in front of the computer for more than 90 minutes will lead to a 50% reduction in blood flow to the knee, thus increasing the chances of thrombosis. It is recommended that you should take a break after 1 hour of computer use, get up and walk around, stretch your arms and legs, move your ankles and stretch your calf muscles. Establish the concept of “sedentary and prone to thrombosis”, and change the habit of “sedentary and immobile” in life, which is a necessary method to prevent thrombosis! 2, walking: move, from head to foot to prevent blood clots Walking is one of the world’s best sports, both simple and easy to do, the effect of strengthening and good, regardless of men and women, young and old, when to start this exercise is not too late. From an evolutionary point of view, walking is the best exercise for human beings. In terms of preventing blood clots, walking can maintain aerobic metabolism, enhance cardiopulmonary function, promote blood circulation throughout the body from head to toe, prevent the accumulation of blood lipids in the walls of blood vessels, and prevent the formation of blood clots.
