How Do Varicose Veins Form? And Other FAQs

Varicose veins are bulging, ropey veins that typically appear on the legs. They’re very common, affecting around 25% of adults in the United States. However, common signs of varicose veins include bulging and twisted veins that appear twisted and may be visible under the skin’s surface. You may also observe aching legs, swelling, and the appearance of small red or purple spider veins. So what leads to the formation of varicose veins?

The formation of varicose veins starts with our body’s internal circulatory system, which consists of the heart, veins, and arteries. The veins, or the vessels that transport deoxygenated blood back to the heart, are equipped with tiny valves that close to prevent blood flow from traveling backward. When the valves weaken, the blood can pool and collect in the leg veins.

Varicose veins can form when the valves inside veins that move blood from the legs back up to the heart become weak and stop working properly — this condition is known as chronic venous insufficiency. When the vein valves responsible for smooth blood flow to the heart against the force of gravity become damaged or defective, blood can’t flow normally and builds up in the leg veins. This causes the veins to swell, eventually leading to varicose veins.

Several factors can increase one’s risk of developing varicose veins. Many of these are related to age and physical inactivity. As we age, the walls of our veins become more fragile, decreasing their effectiveness of circulation. This means that the older we get, the greater our chance of developing varicose veins. Additionally, an inactive lifestyle results in weakened veins due to lack of activity.

Pregnancy is another common risk factor for varicose veins. During pregnancy, a woman’s body endures physical and hormonal changes, which can cause veins to become weaker. In addition, the baby’s increasing weight can put extra pressure on these veins, causing them to swell and become more visible.

Standing or sitting for extended periods can also increase one’s risk of developing varicose veins. This is due to gravity’s added pressure placed on the lower extremities. To help reduce the risk associated with this habit, it is important to take a few moments each hour to stand up, stretch, and walk around to give your legs a break.

Genetics can also determine one’s risk of varicose veins, as certain genes may cause weaker veins. Additionally, people that have suffered an injury may experience weakened veins and a higher risk of varicose veins. Individuals with occupations that involve long periods of sitting or standing, such as nursing, teaching, or driving, also have a higher risk of vein problems.

By understanding the risk factors for varicose veins, we can make educated decisions about reducing our risk.
