Causes of Varicose veins
There are specific factors that increase the risk of developing varicose veins:
- Heredity is one of the main causes.
- Women are four times more susceptible to venous reflux than men, because their hormones have a significant impact on vein walls, which is more noticeable during pregnancy.
- The loss of tissue elasticity due to aging weakens vein valves.
- In rare cases, an anomaly within the deep venous system can cause varicose veins.
Other factors can also hasten the onset of varicose veins:
- An increase in body weight, which increases blood pressure.
- Standing or sitting for long periods of time, because blood pressure in the lower limbs is influenced by gravity.
- Physical trauma to the legs can sometimes damage blood vessels.
