Varicose veins are those veins which become enlarged, widened owing to an overflow of blood. Varicose veins generally happen in legs and feet and the veins generally turn red or bluish in color.
What causes varicose veins?
Varicose veins are generally caused by:
- Weakened Valves: There are tiny valves in your veins which regulate the flow of blood. When the valves get weakened, it gets enlarged resulting in leakage and backward flow of blood. This causes the veins to swell and widen.
- Gender: Research suggests that women are more prone to varicose veins than men. Certain hormones in women tend to make the valves weak and loose which leads to leakage of blood.
- Genetics: It is said that varicose veins are hereditary. If your family member has this, you are at risk of having varicose veins.
- Age: Age can also cause varicose vein. With age, our veins lose its elasticity causing the valves to work improperly.
- Overweight: Being overweight can generate extra pressure on the veins which in turn may cause leakage.
- Pregnancy: During pregnancy, the amount of blood flows increases, putting extra strain on the veins.
Less commonly, varicose veins are caused by such diseases as phlebitis (inflammation of the veins), blood clots or any obstruction to blood flow in the veins, or congenital abnormalities of the veins.
Venous disease (disease of the veins) is generally progressive and may not be prevented entirely. However, in some cases, wearing support hosiery, maintaining a normal weight, and regular exercise may be beneficial.
