If you look closely, you will notice that some people have different shades of green tendons on their legs, arms, neck, and head. Some of the green tendons are hidden under the skin, and some of the green tendons are very obvious.
Especially those with strong muscles are more likely to have green tendons, so when we see those people with obvious green tendons, we will subconsciously feel that this strength is strong and healthy.
Indeed, green tendons can indeed reflect health status to a certain extent. However, it may not be quite the same as we think, or even the opposite.
Green tendons are not tendons, but blood vessels!
Although there is a word "tendon", it is not actually tendon, and green tendon is just a more popular term. Clinically, green tendons generally refer to veins, and what flows inside is dark red venous blood.
Our circulatory system is composed of the cardiovascular system and the lymphatic system, in which the number of veins is large, the diameter is thick, the wall is thin, and the expandability is large.
In particular, veins with a diameter of more than 2 mm often have paired half-moon valves to ensure the centripetal flow of blood and prevent blood from refluxing.
Seeing this, some people may wonder, why is the blood dark red when seen through the skin?
The reason is simple, because our skin absorbs light while it also reflects light on the skin near the superficial veins. Because red light is more penetrating and can reach the blood vessels and be partially absorbed by hemoglobin, while blue light is reflected more, this results in the veins we see being close to cyan.
The eruption of green tendons in these parts may be an early warning of a serious illness!
Most of the time, it is normal for the green tendons to bulge, but if the following parts often have green tendon bulges, it may indicate that there are some problems in the body, you can take a look at it.
(1) Green tendons appear on the head and face
There are green tendons on the forehead, which are generally caused by long-term stress, excessive fatigue, nervousness and depression, etc., which can generally be relieved after appropriate rest. If you often have bruises on your forehead, you need to be further tested for diseases such as diabetes and hyperthyroidism.
If there are green tendons in the temples, it is generally accompanied by symptoms such as dizziness and headache, if the green tendons are twisted and raised, it often indicates cerebral arteriosclerosis, and if the green tendons are purple-black, it may be a sign of stroke.
The presence of green tendons on the bridge of the nose often indicates a risk of gastrointestinal diseases, and patients are also prone to symptoms such as abdominal pain and bloating.
(2) Green tendons appear in the neck
The veins in the neck are the jugular veins, which are generally responsible for backing up blood in the head and carrying it back to the heart and lungs through the superior vena cava. If the muscles in the neck erupt, we call it jugular venous distention, which is often one of the most important indicators to observe for heart disease.
If both jugular veins are distended with hepatomegaly and leg edema, right heart insufficiency, pericardial effusion, and constrictive pericarditis should be considered.
(3) Thoracic blue muscle
Some female friends will have green tendons and bulges on their chests, and most of the time they don't pay much attention to it, and often think that it is caused by thin skin.
Modern medicine believes that the green tendons in the chest may be related to the strong secretion of estrogen, and at the same time, physical factors such as ill-fitting underwear or wearing too tightly have caused problems with blood circulation and supply. Therefore, if there are green tendons in the chest, it is necessary to be alert to the occurrence of breast hyperplasia.
(4) Abdominal blue muscle
The subcutaneous veins of the stomach are relatively deep and covered by thick fat, so there are generally no green tendons.
However, once the abdominal wall veins appear to be visible to the naked eye, it is likely to be a sign of liver disease, because the liver lesion will increase the resistance of the abdominal veins to return, and eventually appear thicker and straighter green tendons.
The most typical ones are adult cirrhosis ascites, syndromes associated with advanced cancer, and so on. Therefore, if there is a green tendon in the abdomen, we must attach great importance to it and seek medical examination in time.
(5) Green tendons appear on the hands
In women, the presence of transverse bruises on the tiger's mouth may indicate breast diseases, such as breast hyperplasia, breast fibroids, and breast cysts. Since the thumb side is the area that responds to the heart and lungs, the presence of green tendons on both thumb sides may have a higher incidence of heart disease.
It should be noted that the green tendons on the back of the hand indicate that the patient is prone to backache or back muscle tension, and there is a certain relationship between the green tendons on the back of the hand and blood lipids.
(6) Green tendons appear in the lower limbs
Those who sit or stand for a long time may have green tendons on their legs, and the longer the time, the more obvious the green tendons are, and sometimes accompanied by symptoms such as swelling pain and discomfort, which is actually a typical varicose veins of the lower limbs.
When varicose veins in the lower limbs are formed, the superficial blood vessels will become varicose like earthworms, and the varicose veins will appear in a lump or nodularity. Most people think that varicose veins have no effect except for the unsightly points, but they don't know that long-term blood accumulation in the lower limbs will affect blood clotting, and pigmentation will appear on the skin, and even dermatitis and ulceration will appear.
Some patients will also cause venous thrombosis in the lower limbs, if the blood clot from the superficial vein to the deep vein, with the blood flow back to the heart, into the pulmonary artery, it is likely to lead to pulmonary embolism, and cause sudden death, so we must pay attention.
There's no need to worry too much about these green tendons!
Sometimes, the obvious bulge of the green tendon is not necessarily caused by the disease, it is likely to be just a normal physiological phenomenon, such as the following are the common physiological causes of the bulge of the green tendon.
(1) People who exercise a lot of daily life
People who usually exercise or do a lot of physical work, because of the relatively large amount of exercise, often need more blood supply to the limbs, in order to adapt to this situation, the heart will increase the pumping volume, which will lead to a corresponding increase in blood flow in the arteries and veins.
In addition, because the vein wall is a relatively loose structure, the blood flow over a long period of time will make it thicker and more distended, so the green tendons are more obvious. As a special reminder, this kind of green tendon is generally concentrated in the back of the hand and limbs and other places where there is usually more force, and if the green tendon does not appear in these positions, it also needs to be paid attention to.
(2) Elderly
Due to the age of the elderly, fat atrophy, the skin will be thinner, and the atrophy of muscles reduces the support and restriction of veins, so the green tendons will also be more obvious.
(3) People with thin body and white skin
People with thin bodies generally have less subcutaneous fat, so the veins and blood vessels will be more obvious, while people with white skin are more likely to bulge the veins because of the better light transmission of the skin.
Therefore, it is not necessary to be nervous immediately when you see the green tendons flare-up, but you should usually observe the changes in the green tendons in various parts of your body. If there is an abnormal green tendon, or the green tendon is not the same as before, you should pay more attention to it and seek medical examination and treatment if necessary.
