Varicose veins

Abnormally dilated and tortuous veins, usually occurring in the legs. A vein can dilate if blood pressure increases, for example because the valves in the vein are not functioning properly, or because flow of blood out of the vein is restricted. The original condition is also important: some people have leg veins with naturally less rigid walls. Varicose veins are more likely to occur in pregnancy if the patient has a job involving standing or is overweight. Varicose veins of the leg look like twisted blue cables under the skin. The legs feel tired and heavy, to a lesser extent when they are moved. There is often no clear link bewteen the severity of the condition and the extent of the varicose veins. Three principal treatments are possible. Elastic support stockings close the veins by pressure and reduce discomfort, a simple but effective method particularly recommended in mild cases or during pregnancy. Treatment by injection involves the introduction of an irritant into the veins, causing the wall to become inflamed and the varicose vein to shrivel and close. Alternatively the veins may be completely removed by surgery.
