Causes of Vein Disease

Varicose veins and other vein problems are very common and can affect anyone. Although there is not one specific cause of varicose veins, there are various risk factors that increase your likelihood of developing these vascular conditions.


People with a family history of varicose and spider veins are significantly more prone to these conditions. About half of all people who have varicose veins have a family member who has them too.


Women are at greater risk of developing varicose veins due to the hormonal changes that occur during puberty, pregnancy, and menopause. Birth control and other medications containing estrogen and progesterone also increase risk of developing varicose veins.


During pregnancy, there is an increase in the amount of blood in the body, causing veins to enlarge. The hormones released in a woman’s body during pregnancy can weaken vein walls, which can lead to valve dysfunction and blood pooling.


Varicose veins are common in patients between the ages of 18 and 35. As you get older, the valves in your veins might weaken, therefore increasing risk of developing varicose veins.

Sitting or standing for long periods of time

People who sit or stand for a prolonged period of time due to their daily activities are more susceptible to varicose veins. Lack of movement forces your veins to work harder to pump blood back to the heart.


Being overweight puts extra pressure on your veins, increasing your risk of developing varicose veins.


Any trauma to the leg, due to a recent surgery or an injury, could cause your valves to malfunction.

There are other factors of a person’s lifestyle that may contribute to the development of varicose and spider veins. These include:

  • Clothes that bind or otherwise impede proper circulation
  • Chronic constipation
  • High-heeled shoes
  • Heat
