What Causes Varicose Veins?

Varicose veins – or unsightly enlarged veins that stick out prominently from your skin – are a common medical issue. They are a vein or vein that appears twisted or enlarged along your skin’s surface – often in the legs and ankles — and are a cosmetic blemish that usually do not cause any serious health complications, though it’s possible they could trigger health problems. Varicose veins are caused by weakened valves in your veins. These valves are one-way and ensure blood flows from your legs to your heart. However, when they aren’t operating normally blood will accumulate, and as a result pressure will build up and the vein will become enlarged and appear like twisted tree trunks running up your leg. They will also become discoloured, appearing dark blue and swollen.

There are some key causes of varicose veins.

The simple fact of getting older is one of them. As you age, your veins lose some of their elasticity, becoming stretched, and the valves can also lose some of their strength.

Another cause – one specifically for women, who run a greater risk of developing varicose veins – is pregnancy. This is because during pregnancy, the flow of blood from your legs to your pelvis decreases. This change occurs to support the healthy growth of the fetus. But what’s good for baby is not necessarily good for mother, as varicose veins can emerge during the late stages of pregnancy, and also be caused by hormonal changes.

Other facts that can result in varicose veins include family history, and being obese or standing or sitting for long stretches of time – both factors that increase pressure on your legs.
