Venous insufficiency and especially the appearance of varicose veins are aggravated by prolonged sitting or standing and an overall lack of exercise. The blood which is controlled by gravity does not return properly to the heart through the vein because the muscles are not functioning properly as a pump in order to assist the blood to return to the heart. When blood cannot be properly returned through the vein, it can pool in the legs causing increased pressure and swollen veins. Exercise helps move blood up your legs. 

Gender: 

3 out of 4 patients are women. In fact, the veins are sensitive to the development of hormone levels, such as progesterone and estrogen. In general women have to contend with significant changes of these hormone levels during menstruation, pregnancy and menopause. 

Number of Pregnancies:

The ratio of women suffering from venous insufficiency increases as the number of pregnancies increases, as much as ⅓ from the fourth pregnancy. Therefore, a pregnant woman must pay close attention to her legs and not hesitate to consult a doctor when symptoms appear, even the slightest change. 

Heredity:

Heredity is one of the main risk factors for developing venous insufficiency.

If either your mother or father suffers from venous insufficiency, the chances that you too will suffer are 1 in 4. In fact, the risk of developing varicose veins can be close to 100% if both parents suffer from this condition. Especially in this case, one must watch closely for symptoms (heavy and swollen legs, pain or muscle contraction) and consult a doctor immediately if symptoms appear. 

Heat is responsible for vein damage. Veins become enlarged and then they cannot adequately return venous blood back to the heart.  

Obesity causes additional pressure to the venous system of the lower legs triggering the condition of venous insufficiency. 

Age: 

Amongst the older population, venous insufficiency is much more common. 65% of people over the age of 60 suffer from this condition. It is important to note that this condition does not suddenly begin at this age, and over the years it develops.  Therefore, one must consult a doctor as soon as possible when symptoms appear to prevent further complications.
