It is unscientific to see if the blood vessels are blocked. Although the blood vessels in the foot can reflect some blood vessels in the whole body, it is not certain whether there are blood vessels blocked, especially those in the cardiovascular system, lungs and brain, which have little to do with the blood vessels in the foot. There are also microvessels, such as renal blood vessels and fundus blood vessels, which are very thin and cannot be reflected on the feet. Clinically, the following tests are mainly used to judge whether blood vessels are blocked, such as blood lipid analysis, color Doppler ultrasound, CT, magnetic resonance, arteriography, intravascular ultrasound and so on. These tests can intuitively reflect whether there are plaques and blockages in blood vessels, rather than simply looking at the feet.

Whether blood vessels are physically and mentally healthy can be realized by ordinary patients themselves. First of all, patients are basically differentiated according to age and other conditions. For example, patients over middle-aged and elderly people, coupled with excessive greasy diet, obesity, smoking and alcoholism, have a high probability of suffering from vascular diseases. Secondly, patients can observe the veins on the surface of their own skin, for example, patients can see whether there are venous protrusions in the superficial part of their skin.

If the thenar vein is obvious, it means that the cardiopulmonary function is weak and it is easy to catch a cold. If the veins in the temple are prominent, the patient is likely to suffer from hypertension or migraine. In addition, patients can observe their own veins at the base of the tongue. If the vein at the base of the tongue is prominent, it means that the patient has a problem with the blood circulation system, such as heart disease or stroke.

The primary factor of blood vessel blockage is blood viscosity, long-term stress on some blood vessels or damage to blood vessel walls. Therefore, in order to avoid blood vessel blockage, we must manipulate the blood sugar level, correct and treat hyperlipidemia immediately, pay attention to low-salt and low-fat foods at ordinary times, and eat less greasy and greasy ingredients. In addition, hypertension and hyperglycemia are also very harmful to blood vessels, which is also the cause of blood vessel damage.

Usually try to reduce the long-term pressure on some blood vessels, such as long-term bed rest, pay attention to the theme of moving legs, and reduce the blockage of blood vessels in legs. Usually pay more attention to physical exercise and strengthen exercise. Physical exercise can speed up the blood circulation system, especially aerobic exercise to lose weight can reasonably prevent blood vessel blockage. Regular physical examination on time every year, correct and treat any abnormal situation immediately, and take oral drugs for anticoagulation immediately if necessary.
