What are varicose veins?
Varicose veins are the distortion and expansion of veins in certain parts of our body.
Keywords: distortion + expansion, simple vasodilation is not necessarily varicose veins.
The most common parts are in the lower extremities. Others include the spermatic cord, digestive tract, pelvic cavity, and many diseases are related to varicose veins, such as hemorrhoids.
Varicose veins in the right calf, also in the ankle
Why do varicose veins appear? High pressure!
Medicine is not perfect, it is not one-to-one causal, either black or white science.
Human beings live in the world, constantly interacting with the environment, and physical problems are multi-factorial, and varicose veins are no exception.
Can be roughly divided into congenital and acquired factors.
Many patients have a tendency to have a high incidence in families. Although it cannot be said to be a genetic disease, it is related to genetic conditions and there are some minor problems with blood vessel elasticity. There are smooth muscles and collagen fibers on the walls of the veins to maintain the elasticity of our blood vessels. It is not important what they are.
Let’s make an analogy:
We like brand-name tires. Because the manufacturers are different, the quality of the products is different. Some are easy to bulge, and some are easy to use.
For the time being, people who are prone to tire bulging are those who are susceptible to varicose veins.
Of course, don’t worry too much. Natural selection allows us to live today, indicating that there must be many other advantages. This small defect is not a problem, and varicose veins are not incurable.
The cost of evolution:
After human beings stand up, they must pay a physical price to develop their brains to occupy the earth. Varicose veins are one of them.
Monkeys are on all fours, and their heart height is no more than tens of centimeters. When humans stand up, their heart height is generally more than 1 meter.
Physics tells us that the higher the water column, the greater the pressure in the lower part.
Anatomically, the farther the blood vessel is from the heart, the thinner the blood vessel and the thinner the blood vessel wall.
Therefore, the thinner blood vessels in the calf bear more pressure and naturally expand easily.
Teachers, nurses, shop assistants, security guards, etc., this is a high incidence of varicose veins. Because you need to stand for a long time in a professional environment. It is recommended that the teacher should not be on the three-foot podium. The place is small and it is impossible to walk around.
The most typical is during pregnancy, because the uterus enlarges, it will compress the veins of the pelvis, which will increase the pressure of the lower limbs and increase the possibility of varicose. In addition, there are also changes in hormones during pregnancy, which also have the effect of expanding blood vessels. The two forces give women a lot more chance of getting varicose veins.
General exercise will not increase the probability of varicose veins, but with the increase in fitness, in recent years, it has been found that many people have aggravated varicose veins in a short period of time, which is related to weight-bearing exercise. Such as lifting a barbell, squatting with weights, etc.
The reason is that when the breath is held, the pressure in the abdomen increases, and the veins passing to the lower limbs naturally expand.
Therefore, for people with signs of varicose, weight-bearing squats are not recommended.
Varicose veins can also occur in post-deep vein thrombosis syndrome, KTS syndrome, cockeet syndrome, etc., which can be roughly recognized by experienced doctors based on medical history and visual examination.
Veins will also be stressful
In short, as long as the factors that can increase the pressure of the superficial veins of the lower extremities, they may promote the occurrence of varicose veins.
Varicose veins, in essence, it is not a disease, but can be regarded as a clinical phenomenon.
