What are varicose veins due to and what causes varicose veins

Weakness of the venous wall, venous valve defects, and persistently elevated pressure in the superficial veins are the main causes of superficial varices.

1.Congenital weakness of the vein wall or venous valve dysfunction, such as absent or hypoplastic valves. As a result, the vein wall is prone to dilation, and the insufficiency of the proximal venous valve causes blood to flow backwards, further affecting its branches, and eventually causing varicose veins.

2.Prolonged standing is an important factor in varicose veins of the lower extremities. The vertical gravity of the blood column increases the venous pressure of the lower limbs, and the reflux can directly cause the destruction of the saphenous vein valve, so the saphenous varicose vein is more common in workers who stand for a long time.

3.Varicose veins of the lower extremities can occur in pregnant women or in patients with pelvic tumors due to increased intra-abdominal pressure and obstruction of venous return to the lower extremities.

Varicose veins refer to varicose veins that dilate due to a series of factors such as blood stasis and weak venous walls, resulting in varicose veins in many parts of the body. Varicose veins are also a common and frequent disease of vascular diseases.

The first stage is that the affected limb often feels sore, heavy, swollen and painful, easy to fatigue, and fatigue; In the second stage, the appearance of superficial veins is dilated, distorted, or even tortuous or lumpy, forming a "green tendon bulge", which is more obvious when standing, and the feeling of swelling and pain continues to increase.

Patients with severe varicose veins can also have mild edema and pigmentation in the lower part of the lower leg, and varicose veins of the lower limbs are related to whether everyone can run, which is also the most critical part of the impact.

Congenital weak vein wall, long-term standing and sedentary, long-term excessive pressure on the lower limbs.

Health experts and Li enough to embellish their lives this time, I believe that many people do not understand varicose veins. In fact, it is mainly due to many factors such as blood stasis and weak venous walls, which leads to the occurrence of vein tortuosity and dilation. Pay attention to health, in fact, varicose veins can occur in many parts of the body, and in general, the most common part of varicose veins is in the lower limbs.

So, what causes varicose veins?

For the causes of varicose veins, let's take a closer look:

1. There are many reasons for varicose veins of the lower limbs, the most common is simple varicose veins of the superficial lower limbs, and the main one is the insufficiency of the femoral saphenous vein valve. Another important ** is seen in primary lower extremity deep vein valve insufficiency.

2. In addition, the syndrome after deep vein thrombosis of the lower limbs is due to the poor deep venous return, so the superficial veins compensate for the tortuous dilation. Arteriovenous fistula of lower limbs, venous malformations, hyperosteopathy syndrome can also have superficial varicose veins of the lower limbs; Obstruction of inferior vena cava return, such as Budd-Chiari syndrome, can also lead to varicose veins in the lower extremities.

Varicose veins have certain clinical manifestations:

1. The blood vessels on the surface will be varicose like earthworms, and then you will see obvious protrusions**, resulting in varicose lumps or nodules.

2. You will feel soreness in the legs, and then there will be pigmentation, continued scaling, itching, and ankle edema;

3. The limbs have a strange feeling of pinpricks, itching, numbness, and burning.

4. The patient will obviously feel the increase in epidermal temperature, and even pain and tenderness.

For patients with more serious conditions, it is necessary to carry out the corresponding ** in time. During pregnancy, women should take more care of their legs, and at the same time, they should pay more attention to rest to help promote blood circulation. Properly regulate your usual diet, eat more fresh fruits and vegetables, and supplement vitamins.

The causes of varicose veins are both congenital and acquired. Congenital refers to genetic factors, which run in families, and sometimes it is common to see two fathers and sons, and several brothers to see varicose veins at the same time. Secondly, the acquired factor has a lot to do with standing and sitting for a long time, and there are several occupations that are very high-risk varicose veins people, including teachers, store salesmen, hairdressers, cooks and other workers who stand for a long time, and are very prone to varicose veins.

The second is to sit and stand for a long time, that is, office sedentary people, it is also very easy to get varicose veins, because when sitting, there should be a bend in the knee and thigh, so that the blood will flow back and forth through these two bends, and the resistance will increase, which will increase the probability of varicose veins in the lower limbs, including office workers and IT practitioners. Some students get varicose veins at a young age, which has a lot to do with sitting for a long time. Then there are obese people, if people with a particularly large weight stand up, the burden on their legs will be heavier.

Varicose vein ulcer refers to the fifth and sixth grade lesions of varicose veins, which are caused by the improper excretion of toxins on the legs, and the local necrosis and ulcers on the legs. Its principle lies in the fact that the vein itself is a reflux blood vessel, which excretes the blood of the leg vein through the lungs to excrete the metabolic waste of toxic substances, and turns it into nutrients through the arterial blood and back, playing the role of circulation. Blood goes from the bottom to the top, gravity water flows to the low, why it can go up against gravity depends on two factors:

On the one hand, the calf muscles will contract every step of the person, promoting the upward flow of blood; In addition, the venous return has the effect of suction, which mainly means that there is suction when the person breathes and inhales, and when the heart contracts, it has suction during diastole, which can promote the blood to go up. The vein has a special structure called a valve, the valve is equivalent to a one-way valve, and when the blood goes up, it closes, and it closes tightly, so that the blood can be blocked and the blood does not flow backwards. But basically after the diagnosis, the valve is not tightly closed, the blood because of its own gravity, and even a gap to the downward regurgitation, the reflux of toxic substances and metabolic wastes in the blood can not be excreted, it will be stagnant on the legs, it will be leg pain, swelling, itching, after a long time, it will become very thin, and the pressure will break to form ulcers.

What are varicose veins? Why varicose veins.

There are two main causes of varicose veins in the lower extremities:

Internal causes: congenital venous wall weakness and venous valve insufficiency (familial genetic factors).

External causes: increased venous pressure in the lower extremities (acquired factors such as age, prolonged standing or sitting, pregnancy).

There are two causes of varicose veins in the lower extremities:

1. Internal causes: The so-called internal causes refer to the weakness of the patient's own vascular wall and the insufficiency of the vascular venous valve, both of which are internal causes, that is, caused by the patient's own or genetic factors;

2. External factors: mainly refers to the increase in the pressure of the veins of the lower limbs, which is related to the working environment of the patient, such as long-term standing or long-term sitting, pregnancy in women, long-term constipation, etc., and the increase of these factors can cause the increase of venous pressure in the lower limbs.

The occurrence of varicose veins is often caused by a mixture of internal and external causes.

I'm a firefighter! There are some people in our unit who suffer from such diseases, and such people are often caused by excessive exercise... Because they are our technical backbone, they are very good in physical fitness, so it should not be infrequent exercise, on the contrary, excessive exercise!

Varicose veins can be caused by prolonged standing, venous valve function problems, and deep venous branch stenosis and blockage.

Standing for a long time and not exercising may also be genetic
