The blood goes out of the heart across the blood glasses named "arteries" towards the organism, to take him oxygen and nutrients, and tackles from any part of the body his trip back to the heart across the glasses called veins. The first part of the way is easy, since the heart is in charge of impelling it ahead, but it demolishes it from some areas it is more difficult, since nothing pushes it back towards the heart. The regions that are over the same one have it easy: the blood, for effect of the gravity, turns with scarce effort. The regions that are much underneath and very far of the heart they have it, on the contrary, very difficult, since there is a long way for doing, that also is against the gravity.
Because of this, the veins of the legs have valves, so that the blood that it is raising cannot go down again for its own weight. The pumping is done on having moved the muscles of the legs, this way, walking is an excellent exercise to activate the circulation of the legs.
When for diverse reasons of the body it turns out to be impossible to do that the blood returns fluently to the heart to him, this one is stagnating, and so that it has place the glass (the vein) is dilating. In the first moment, if the venous comeback is favored the above mentioned dilation disappears and the vein is normal again. But if it lasts too much, the vein one goes a long way, it "is" "transferred", the valves stop working and the problem will not be already solved when the comeback is favored.
There are called they to the extensive glasses varicose veins, and they can appear in any place of the organism, although the most frequent are in the legs.
The varicose veins affect 1 of every 10 persons, approximately, and of twice more frequent form in women, fundamentally for effect of the pregnancies (that worsen the venous comeback).
The varicose veins tend to become bigger with the time, and can become a cause of edemas (distension) in the legs and varicose ulcers, which often are preceded of brown pigmentation of the skin.
To avoid to sit down or to be standing up calmly during long periods.
If the work or the daily life are sedentary, there is that flexionar legs and ankles often, to get up and to walk. At the end of the day, it will help to relieve any tumefaction raising the legs a few centimeters over the level of the heart (for example, knocked down).
The regular exercise (walk, bicycle, swimming) diminishes the pressure in the veins and relieves the inconveniences.
Compressive averages. They provide immediate and lasting mitigation, on having compressed the varicosidades and having improved this way the venous comeback. They are usually designed so that the maximum compression happens about the ankles and calves. They can be indicated also in the pregnancy.
Surgery. The varicose veins can come out by means of surgical intervention, which must include the split of the biggest vein and of his taxpayers or collateral ones. The long-term benefit in appropriate patients is very high. The surgery usually complements itself with the varicose veins sclerosis.
Varicose veins sclerosis. For varicosidades kidlings, but with unacceptable esthetic effect, it usually use a skill that consists of injecting straight into every varicose superficial vénula a chemical substance that produces an inflammation of the vénula, which then follows of healing (sclerosis) of the same one. The skill includes in general multiple meetings. If it is realized correctly, it is practically painless and it exempts of complications.
