Why do varicose veins occur?

The doctors have not yet been able to identify a specific range of causes of varicose veins. In some patients the disease begins to develop under the influence of a number of unfavorable factors, in others from malnutrition or mild muscle overload. The characteristics of the body of a particular person play an essential role in this.

How to recognize the disease at an early stage

There are many causes of varicose veins in the legs. This is bad inheritance and physical inactivity and abuse of fats. Recognizing the disease at an early stage is important if you are to take care of your health. If, in the late afternoon, suddenly you feel a feeling of heaviness in your legs, you need to go to a phlebologist. One of the symptoms of vasodilation is thought to be night cramps. If they were not preceded by physical activity, then you should go to the hospital.

The legs with varicose veins often have a higher temperature than the rest of the body. At the end of the day, in addition to being tired, the patient may experience a burning sensation. One of the early manifestations of the disease is bleeding from bluish or bluish veins on the surface of the skin. Of course, if this is due to the genetic structure of your body, then there is no need to panic, but if you have never encountered such a phenomenon, then it is time to see a doctor.

Symptoms

The main cause of varicose veins is physical inactivity. The blood stops circulating normally around the body, so it stays in the limbs. The disease may not manifest itself at all for a long time, but then the patient may have very unpleasant signs of the disease, such as cramps and a feeling of heaviness in the legs. The first symptoms of the disease are:

  • severe swelling of the legs;
  • the appearance of spider veins on the body;
  • protruding veins under the skin;
  • Changes in the temperature of the extremities;
  • Heaviness in the legs at the end of the day.

If these signs of the disease are found, a person should see a phlebologist. Vascular changes can be reversed in the initial stages, but the condition of the distended veins cannot be improved as the disease progresses. It will only be possible to prevent damage to them or remove them in order to normalize blood flow.

As the disease progresses, a person may notice pronounced swelling of the legs. They don't go away even after a long break. In the second stage of the disease, the patient begins to feel pain when overworked. It is enough to sit at the computer for a while or to go up the stairs to create uncomfortable symptoms.

diagnosis

The causes of varicose veins are often closely related to human habits. If the patient likes to sit constantly and tossing one leg over the other, after a while the vessels suffer from excessive pressure and loss of elasticity due to the mechanical stress on one limb. The following diagnostic methods can determine the causes of varicose veins on the legs and the degree of disease progression:

  • Ultrasonic method. It allows you to get information about the condition of blood vessels to determine the degree of their damage.
  • General and biochemical blood tests. With its help, it is possible to identify abnormalities in blood clotting, a tendency to thrombosis.
  • Venography. With this examination method, the human circulation is filled with contrast medium. The pictures show not only the general structure of the veins, but also nodes and other vascular pathologies.

Where do varicose veins come from?

Not all people know what causes varicose veins. The initial cause of the development of the disease should continue to be a dysfunction of the vascular valves. With this pathological condition, blood begins to linger in the veins. Hereditary varicose veins develop according to the same scheme, but in addition to the malfunction of the valves in such people, the walls of the vessels are often less elastic. Under the influence of one or more reasons, varicose veins in the legs begin to progress very quickly.

Are varicose veins inherited

The genetic factor plays a crucial role in the occurrence of varicose veins, which is why many doctors view varicose veins as a hereditary disease. If we talk about certain genes that are responsible for the development of this disease, they have not yet been identified. Varicose veins are inherited, but not all people with a congenital predisposition develop. One or more factors are needed that catalyze the process of stretching the vessel walls.

DNA and the transmission of varicose veins by heredity

The causes of varicose veins are not always linked to a genetic predisposition to the disease. The most common patients in phlebological clinics are cooks and professional athletes, because strong and continuous mechanical action provokes the development of vascular valve dysfunction. If you look at the varicose veins in children, the lifestyle of the parents before conception and during pregnancy, i. e. the so-called thyroid factors, has a major influence.

The causes of varicose veins

The causes of varicose veins are divided into major and minor. The first group of factors directly affects the venous circulation, and the second, with a certain probability, can provoke or accelerate the development of the disease. 90% of patients who see vascular surgeons and phlebologists are exposed to both types of factors.

The main causes of the disease

The reasons for the appearance of varicose veins depend on the patient's lifestyle. The attitude towards one's own health plays an important role in the development of many diseases. Genetic varicose veins can also be prevented if you follow the recommendations of doctors. The main causes of the development of the disease are:

  • hereditary tendency to varicose veins;
  • the negative effects of hormonal fluctuations on the state of the vascular system;
  • Use of drugs that affect blood pressure or hormone production.

Secondary causes

The secondary causes of the development of varicose veins include all factors that indirectly affect the condition of the vessels. These are mainly uncomfortable clothes. Jeans that are too tight or shoes that put too much pressure on the foot can affect blood circulation. Excessive physical activity is another secondary factor that contributes to the formation of varicose veins. Exercise is important for the normal function of the organs, then working with heavy free weights often has the opposite effect.

Mental disorders also affect the vascular system. Almost all veins contain nerve endings. In depression or under the influence of psychotropic substances (alcohol, tobacco), impulses begin to flow to these nerve endings, which leads to increased vasoconstriction. This increases the pressure in the veins and the vessel walls begin to stretch.

Varicose veins of the legs

The causes of varicose veins on the legs are pretty common. First and foremost is physical inactivity, which leads to blood congestion in the legs and hips. The influence of inheritance should not be ruled out. If the patient had ancestors who suffered from problems with the vessels of the lower leg, then the same situation can arise for him. Doctors do not consider the appearance of varicose veins on the legs as a 100% deviation from the norm, since gravitational forces are constantly acting on the lower extremities. This leads to a slight dilatation of the blood vessels even in very healthy people. The reasons for the appearance of varicose veins of the extremities are:

  • hard training;
  • Lack of physical activity;
  • injuries to the knees and other parts of the leg;
  • unfavorable working conditions;
  • to be overweight;
  • bad climate (high temperatures are damaging to the veins).

Varicose veins of the thighs

This area of the legs is mainly home to large vessels, so after examining the patient, doctors can tell exactly where the varicose veins are coming from. Doctors believe that the main reason behind the appearance of this nasty disease on the hips is a sedentary lifestyle. This phenomenon is especially common in women, since their blood flow is slower due to the peculiarities of the hormonal background in this part of the body. The causes of varicose veins on the thighs can be as follows:

  • Increase in body weight. It is especially bad when this process is accompanied by pregnancy. The pressure in the pelvic area is already increased, therefore
  • Bad habits. Even if your BMI is ideal and every model will envy you for your figure, frequent smoking and the consumption of fatty foods lead to the development of varicose veins.
  • Inheritance. If your close relatives have had varicose veins, then there is an 80% chance that this disease will manifest itself in you.

risk groups

There are so-called predisposing factors, the effect of which can provoke the expansion of the vascular walls. Work has the greatest impact on a person. With constant standing or vigorous physical exertion (builder, loader, etc. ), the venous system begins to suffer from overload. This also includes the negative influence of high temperatures. Factors that contribute to the development of varicose veins also include:

  • Pregnancy and childbirth;
  • hereditary predisposition to vasodilation;
  • large body weight.

How to prevent varicose veins

Knowing the causes of varicose veins can help prevent their further development. First, it is necessary to maximally reduce the mechanical effect on the veins, that is, to give up the habit of sitting cross-legged and wearing clothes of inappropriate size. If you are prone to constipation, you should reconsider your diet. You need to consume more fiber and vegetables as they activate the intestines. If dietary changes do not help, the person should speak to the doctor to prescribe medication that will normalize peristalsis.

One of the major causes of lower extremity varicose veins is physical inactivity, so a person should improve physical activity. All sports that do not involve excessive physical stress and work with large free weights are suitable for prevention. It is especially useful if you have a tendency to develop varicose veins while swimming. It helps to relieve the joints and normalize blood flow. In addition to exercising, it is advisable to do the following procedures:

  • take a contrast shower;
  • While resting, put your legs on a special pillow so that they are above the level of the heart.
  • consume at least 1, 5 liters of water a day;
  • wear compression stockings if you have a tendency to develop varicose veins;
  • Take long walks every day (at least 3 km).

With a tendency to expand blood vessels, it is necessary to normalize body weight. In this case, it is better if the BMI is a little lower than normal than the other way around, as the presence of a large body fat contributes to an increase in cholesterol levels. In some cases, doctors prescribe special drugs that increase vascular tone and creams for prophylaxis. They should be used according to the instructions for use or the scheme prescribed by the doctor.
