I believe that some people in life will find that the skin on the back of the hands of the elderly is very loose and there will be obvious blue veins, especially when exercising, blue veins will also bulge.
In fact, the bursting blue veins are blood vessels and veins that are vaguely visible under the skin. Especially some men's arms are particularly prominent, while women are not particularly obvious.
In fact, human blood is red, but the veins look cyan from the outside of the skin. This is because the carbon dioxide content in the veins is too high, and the veins blood vessel walls are particularly thin, so they will appear dark red or cyan.
Especially for some people who have been doing physical labor for a long time, the veins on their arms will also be particularly obvious. So what's going on? Let's learn about it today.
1
What is veins?
In fact, there are three main types of blood vessels in the human body, namely arteries, veins and capillaries. The arteries are located in the deep layer of the skin and are generally not visible to the naked eye.
Veals are located on the surface of the skin. Generally, the blue veins we see on our hands are venous blood vessels. If the body has bleeding from the large artery, the doctor will generally supplement the patient's large artery with nutrition, blood or water.
Because everyone's skin condition is different and the absorption of nutrients is also different, especially some people's skin is very tight and very thin, so the blue veins will be very obvious.

Why do some people have "blue veins bulging" on their arms, while some people can hardly see them?
body shape and skin type
In life, some people have relatively thin bodies, and the fat layer of under the skin is particularly thin, so the veins are very shallow, which can generally be observed with the naked eye, especially some people have particularly fair skin, so they will feel that the veins are particularly obvious.
. For some obese people, veins cannot be seen on the surface of the skin, so the blue veins are not particularly obvious and cannot be seen.
Age factor
As people get older, their fat will shrink, their skin will become thinner, and their support effect on the veins will decrease, so the blue veins will be more obvious.
Especially when some people are too strong or angry, their muscles are too tense and their blood pressure rises, which will cause blood vessels to become very obvious, and veins will appear.
Vascular abnormality
If there is a lesion in the blood vessel, it will cause changes in the morphology. If the blood vessels are suddenly raised, this may be due to a return flow disorder caused by blockage. This situation is more dangerous. If the plaque falls off, blood vessel blockage is also prone to occur.
Work reasons
In fact, the nature of the work everyone is engaged in is different. Some people usually engage in some heavy physical activities, their body fat rate is relatively low, and their blood flow rate is very fast when working, causing blood vessels to expand rapidly, so obvious blue veins will appear.

Blue veins appear in these parts of the body. Beware of Cardiovascular and cerebrovascular diseases
Tiger mouth
In life, some young people will have obvious blue veins at the tiger's mouth. This may be a problem of cardiovascular and cerebrovascular malformation. You should seek medical treatment in time for examination.
If the elderly have this condition, they should also be wary of cardiovascular and cerebrovascular emergencies. If the veins are particularly protruding and dark in color, it means that the condition is serious.
Thumb root
Thumb root is a microcosm of coronary artery . If you see obvious blue veins with the naked eye, you should be wary of coronary artery .
If the veins at the base of the thumb are particularly severe and the color is very dark, it means that the condition is relatively serious. If there are still problems such as arrhythmia , chest tightness , angina pectoris, you should seek medical examination in time.
Hydrim
There are also some people with obvious blue veins in their orchidrim, which means that there is abnormal blood circulation throughout the body, especially in middle-aged and elderly people. Generally, this type of people also have cardiovascular and cerebrovascular diseases and three highs. If this situation occurs, intervention should be done early to avoid venous embolism of the lower limbs.
wrist
There are also some people's wrists with very obvious veins. This may cause insufficient blood supply to the heart, and may also cause adverse symptoms, such as irritability, insomnia, angina pectoris, chest tightness, palpitations , etc.
