Healthy human venous blood from the legs to the heart under pressure, which in normal condition is enough to overcome earth's gravity. Disorders of this mechanism, the body is forced to add that pressure to push the blood up.
The result of this process leads to valve failure, which is characterized by blood flow in the superficial veins to the deep. Because of the pressure of the blood vessels is increased, their walls lose their elasticity, stretch and endangered, which leads to the formation of visible subcutaneous nodules bluish color.
Varicose veins not only weaken the external condition of the foot, but cause a lot of complications, some of which is able to chain a person in a wheelchair, while others even lead to death.
Causes the development of varicose veins of the lower limbs:
During pregnancy varicose veins occur most often, because in this period there are global changes in the hormonal levels and increase the body mass.
Men with this disease suffer, if their lifestyle is associated with heavy physical work or long-term stay on his feet – movers. Varicose veins in the legs can occur as a result of some sports.
Comprehensive treatment of varicose veins of the lower limbs with the following method:
In addition, prescribed a special diet, exercises and physiotherapy.
This method to treat varicose veins on the legs is that the affected vein with a needle injected the drug, provide special effects. The venous wall, thus blend together, and the blood vessel stops.
This procedure is done under general anesthesia, after the end of the leg bandage. In the future, the patient is recommended wearing compression underwear to strengthen the therapeutic effect.
Surgery of varicose veins of the lower limbs is specified in the expressed symptoms of the disease, when it threatens the health and life of the patient. Surgery if varicose veins are of several types:
Varicose veins of the lower extremities is a very serious disease, characteristics, that are 40% of adults. If time does not begin treatment of varicose veins mesh foot, the disease can lead to complete disability.
lifestyle or work involves heavy physical loads, prolonged stay in one position (standing or sitting) or constant high ambient temperature;— a significant increase in body weight;
Barriers to the flow of blood in the veins. Such barriers may include: blood clotting, the uterus and the tumor.
Stress and nervous disorders. They affect the condition of the vessels. The wall of the veins have nerve endings, which give them elasticity. When the pressure on them, are exposed to various toxins and alcohol the gleam of the vessels lose tone and expands.
The arterial-venous crossings. Such transitions can take place, because the pressure of blood flow of red blood cells.
Sports overload. The danger in fans raise the bar in the gym. In the presence of a predisposition to varicose veins to overload the legs excessive exercise and heavy lifting are prohibited.
Uncomfortable clothes and shoes. A lot of tight clothing such as skinny jeans can cause varicose veins. Also harmful for narrow shoes and high heels. When choosing shoes, give preference to the broad sole, the wider the base, the less the load on the legs.
All of these factors contribute to varicose veins, increase venous pressure and malfunction of the venous valves. The result is abnormal blood flow in the veins of the lower limbs — reflux (backward flow of venous blood to the deep veins and superficial).
The right blood circulation, when blood flows in the veins of the leg from the bottom up, this is achieved by several factors: the pressure of the blood in the arteries, the contraction of the muscles of the legs during the movements and the presence of valves in the veins prevent the back flow of blood.
Failure of these valves to perform its function causing disturbance of venous blood flow, which leads to hyperextension of the veins. Therefore, blood flow becomes chaotic, the blood stagnates in the veins of the lower extremities (especially the skin), the pressure increases, the blood vessels begin to expand.
Weakened walls of the veins of people of age can lose elasticity. This weakening of the venous walls may lead to their expansion.
Several factors contribute to the development of varicose veins. These are:
Lifestyle factors also play an important role, and people who for a long time, even permanent, is a higher risk of developing varicose veins. This, for example, nurses, flight attendants and teachers.
The weakening of the vessel wall and valvular insufficiency contribute to such diseases and conditions:
