Varicose veins are caused by weakened or damaged valves in the veins. When these valves fail to function properly, blood can flow backward and pool in the vein, causing it to stretch or twist. Several factors contribute to the development of varicose veins:
- Age: Aging causes wear and tear on vein valves. - Gender: Women are more likely to develop varicose veins due to hormonal changes. - Genetics: A family history of varicose veins increases risk. - Obesity: Excess weight puts additional pressure on veins. - Prolonged Standing or Sitting: Long periods of standing or sitting impede blood flow.
