Varicose veins are primarily caused by weakened or damaged valves within the veins. Veins have one-way valves that prevent blood from flowing backward as it travels toward the heart. When these valves don't function properly, blood can pool in the veins, causing them to enlarge and become varicose.
Several factors contribute to the development of varicose veins, including age, genetics, and hormonal changes. Women are more likely to develop varicose veins, especially during pregnancy, due to increased blood volume and hormonal shifts. Obesity, prolonged standing or sitting, and a sedentary lifestyle can also increase the risk of developing varicose veins.
Additionally, previous leg injuries, blood clots, and certain medical conditions that affect blood flow can contribute to the weakening of vein walls and valves. While some risk factors are unavoidable, lifestyle changes and preventive measures can help reduce the likelihood of developing varicose veins.
