What causes varicose veins
February 12, 2009
Varicose veins refer to those swollen, distended veins that are commonly found on the legs. Of course, if you have them, you have even reason to feel bad, both by their sight and by the pain caused by them.
Varicose veins are caused when the walls of the veins in the legs get weakened. Since these veins are placed very close behind the skin surface, event the slightest protrusion is easily visible from outside.
Irregularities that are related with varicose veins get triggered when the tiny valves that are present within the veins are damaged. As these valves do not function properly, blood is forced to “pool” in the vein. The stagnant blood pools that stay within the veins make them bulge out. The major of blood clots formed within the legs include redness and tenderness along the vein.
When such a blood clot, which is medically termed as venous thrombosis, occurs the normal blood circulation is hindered. This leads to other disorders such as swollen ankles, feet and legs, itchy skin, darkening of the skin, formation of scales on the skin surface, changes in temperature in the legs and feet etc. In some patients, such deformities lead to sores and ulcers that appear on the skin. These are termed as venous stasis ulcers.
Treatment and prevention mainly includes self help approach. Whenever a person who suffers from varicose vein disorder takes rest, ensure that his or her legs are kept raised. Keeping the affected leg raised helps in reducing pain and swelling. When the feet are kept high, the blood will immediately get re-circulated back into the body.
It is advisable to avoid standing continuously for a longer period. Ensure that you take breaks from standing. Even walking around for some time is better than continuous standing. People suffering from varicose irregularities should avoid wearing tight knee socks and such other fittings, as it will impair blood circulation.
