Spider veins are small and primarily cosmetic, while varicose veins are larger and associated with health concerns. Varicose veins occur from weakened valves that allow blood to pool, often due to factors like prolonged sitting or standing, obesity, and hormonal changes. Experts emphasize the importance of staying active to prevent these conditions, dispelling myths such as leg crossing causing varicose veins. Genetics also plays a significant role in their appearance, making preventative measures like movement essential.
Hormonal changes, due to pregnancy, menstruation or birth control pills, can also relax vein walls, increasing the risk of varicose veins.
When the valves become weakened or damaged, blood can collect in the veins, causing increased pressure and varicose veins.
