If you recently discovered that you have varicose veins, you may be wondering why? Veins carry blood from your legs back to your heart. Varicose veins develop when the valves in the veins that return blood from your feet and legs to your heart stop working properly. In order for the blood to return to your heart, the veins in your legs have to work against gravity. The contractions in your leg muscles act as pumps and valves in your veins open to let the blood flow towards your heart and close to stop the back flow. When those valves stop working, the blood pools and venous disease occurs.
Multiple risk factors can increase your chance of developing varicose veins. Some include age, pregnancy, standing or sitting for long periods of time, obesity, hormonal changes in women and a family history of venous disease.
