VARICOSE
VEINS TREATMENT
Varicose veins are veins that have become enlarged and tortuous.
The term commonly refers to the veins on the leg, although
varicose veins can occur elsewhere. Veins have leaflet valves to
prevent blood from flowing backwards (retrograde). Leg muscles
pump the veins to return blood to the heart, against the effects
of gravity.
When veins become varicose, the leaflets of the valves no longer
meet properly, and the valves do not work. This allows blood to
flow backwards and they enlarge even more. Varicose veins are
most common in the superficial veins of the legs, which are
subject to high pressure when standing. Besides cosmetic
problems, varicose veins are often painful, especially when
standing or walking.
Varicose veins are more common in women than in men, and are
linked with heredity.
Other related factors are pregnancy, obesity, menopause, aging,
prolonged standing, leg injury, abdominal straining, and
crossing legs at the knees or ankles. Less commonly, but not
exceptionally, varicose veins can be due to other causes, as
post phlebitic obstruction and/or incontinence, venous and
arteriovenous malformations.
