Varicose veins are twisted, enlarged veins, often dark blue in color, near or raised above the surface of the skin. Varicose veins are often a symptom of an underlying condition called venous insufficiency. Any of the vein types may become varicose, but most commonly affected are of legs.

Veins are the blood vessels that return deoxygenated (impure) blood to the heart. Valves in the vein open to allow the blood to pass through and close to prevent the backward flow of blood. In healthy veins, blood travels in one direction only, towards the heart. In contrast, varicose veins are abnormal or damaged veins that have lost their ability to efficiently return the deoxygenated blood back to the heart. Damaged valves in the veins allow blood to collect so that vein walls are stretched until they loose their elasticity and are unable to contract to their normal shape.

Blood leaks back through weakened valves and pools in the vein, distending and twisting the vein. This condition is called venous reflux and is often the underlying cause of varicose veins

Risk factors:
There are multiple causes of varicose veins, and treatments differ by cause and severity of symptoms. most common risk factors are-

1. Obesity
2. Jobs that involve long period of standing
3. Pregnancy, varicose veins associated with pregnancy may cease to be problem after child birth; otherwise they can persist indefinitely

Symptoms Of Varicose Veins

Varicose veins are common and are not always associated with more severe health problems. However, they can become painful, unattractive and worsen over time. Varicose veins can cause legs and feet to swell, create a sense of fatigue in leg muscles and throbbing and cramping at night.

People with varicose veins may notice visibly twisted, swollen veins
just below the skin's surface.

In addition, some will experience discomfort from swelling, throbbing or cramping at night. Additionally, because the skin tissue around the varicose vein may not be receiving enough nourishment, itching or burning of the skin over the vein is not uncommon

Treatment

In cases where the symptoms are mild and limited home treatment can be very successful and medical treatment is usually not necessary.

More severe symptoms such as these may be reduced through one of a number of medical procedures. Only a doctor can determine whether a particular medical procedure is appropriate.

These symptoms may be a sign of an underlying condition called venous insufficiency in which damaged or diseased valves result in backward flow of blood in your leg. Patients with venous insufficiency often benefit from medical treatment.
 

While hereditary can be an important factor in determining who will develop varicose veins, dietary measures and regular exercise may help to prevent them.

Prevention:

There is no way to prevent varicose veins from occurring. However, by adhering to the following suggestions, you may be able to alleviate symptoms of varicose veins and slow down the progression of the condition.

1. Maintain a healthy weight to avoid placing excess pressure on your legs.
2. Avoid crossing your legs while sitting.
3. Do not sit or stand for extended periods of time. Be sure to shift your weight from side to side or get up and stretch every 30 minutes.
4. Avoid tight clothing that might constrict your waist, groin or legs, such as garter belts.
5. Wear elastic support stockings.
6. Control your salt-intake to prevent inadvertent water retention and swelling.
    

Homeopathic remedies often help to relieve discomfort that comes with varicose veins, and may help to prevent their worsening. Individuals with serious cases may benefit from a constitutional remedy, prescribed by an experienced homeopath.
