It is known that gravity affects the blood flow. Heart plays the role of the pump, which provides a constant circulation of blood. For circulatory organs located above the heart, gravity exerts a positive effect. However, in vessels of the lower limb the force of gravity acting against the organism and, sometimes, when failure of venous valves or by reducing the venous tone gravity is sufficient to prevent normal blood flow. In this case, the blood stagnates in the veins, leading to the fact that venous vessels themselves are deformed.
These veins are called varicose. Usually they can be found in the calf muscle on the back of the knee. Approximately every tenth inhabitant of the planet suffers from varicose veins. As a rule, are women aged 30 to 60 years with a birth defect of venous valves. This disease also results in obesity, poor posture, and the conditions when the person has for a long time to stand or sit, and pregnancy. In each of these states is extra pressure on the veins and blood flow in the lower extremities is difficult.
Causes of varicose veins: the absence of venous valves, damage or hereditary defects, so that they are not able to prevent reverse blood flow in the lower limbs, which in turn is due to gravity (thus, the veins fill with blood and dilate); prolonged stay in an upright position, obesity, and high blood pressure is exerted on the veins of the lower half of the body at a voltage of muscles during defecation, and weight lifting and pregnancy.
Symptoms of the disease: twisted, dark blue or purple flowers veins in the legs, irregular brownish pigmentation of the skin in the legs and ankles, intense pain in the legs, occasional cramps in the muscles of the lower limbs, thick veins; ulcerative skin defects on the legs or in the joints.
The disease can lead to complications such as eczema, skin ulcers, severe venous bleeding wound of the lower extremities, thrombophlebitis (inflammation of a certain area of the vein, which is accompanied by the formation of thrombus).
Without therapeutic measures varicose not disappear. However, you yourself can relieve pain and reduce discomfort in the following ways: avoid prolonged standing motionless in one spot. Without exercise, blood stagnates in the affected vessels, the pressure increases. All this leads to water accumulation in the feet, ankles and lower parts of the legs, accompanied by the increase of pain.
Do not forget to regularly move, change body position. In addition, due to physical activity liquid rapidly absorbed by soft tissues, and thereby decrease pain. Wear a special medical pantyhose or stockings, so you let fluid retention in soft tissues. Do not sleep sitting. If you have a long time to sit, bend and unbend his legs in the ankle joint to maintain blood flow. In traveling, pay special attention to the state leg. Do not sit long in one place. Every 45-60 minutes to get up and stretch.
Do not sit close to the fire because this contributes to varicose veins, leads together to fluid retention and discomfort in the legs. Take a bath in the evening. If you take a hot bath in the early morning, it will lead to the re-expansion of the veins and fluid retention and, consequently, pain.
Suffering from varicose veins without heart disease may be advised to sleep in a position where feet are above the heart level. Raise your legs above heart level 3-4 times a day for 5-10 minutes. This is especially useful for pregnant women. Do not eat a lot of salty foods, since in this case; more fluid is retained in the body.
The doctor may prescribe drugs that facilitate or enhance the state of tone of veins. However, when pronounced varicose require sclerotherapy or surgery. Sclerotherapy – a special injection of drugs, whose action leads to decay and overgrowing of varicose veins, which prevents the reverse blood flow. Surgery – is the removal of varicose veins (vein excision).
