Main reasons for varicose veins
Valve malfunction: When blood flows through the veins to the heart, the valves help prevent it from flowing back down. When these valves become weak or damaged, blood accumulates in the veins and the veins thicken.
Standing or sitting for long periods of time: People who stand or sit in the same position for long periods of time due to work experience experience more pressure on the veins in the legs and blood flow slows down.
Aging: As we age, the elasticity of the veins decreases and the valves weaken.
Pregnancy: During pregnancy, the amount of blood in the body increases and blood flow to the veins decreases due to the pressure of the uterus.
Obesity: Obesity puts excessive pressure on the veins.
Heredity: If someone in your family has varicose veins, you are also more likely to get them.
Gender: Varicose veins are more common in women than men (hormonal fluctuations are one reason).
