Varicose Veins: What Causes Them and How to Keep Your Legs Healthy

What makes humans unique among the animal kingdom is our ability to stand upright on two legs. This fundamental ability, however, can also lead to some health challenges, one of which is a condition known as varicose veins. Understanding the anatomy of veins and how they function is key to recognizing why varicose veins develop and how we can manage them.

What Are Varicose Veins?

Varicose veins refer to the swollen, twisted veins that appear under the skin, often in the legs. These veins are part of the circulatory system, which is responsible for transporting blood throughout the body. In a healthy circulatory system, blood flows upwards from the feet to the heart, assisted by the valves within the veins.

There are two main types of veins in the legs:

• Superficial veins: These veins are located just under the skin’s surface.
• Deep veins: These veins run through the muscles of the legs.

The veins in the legs are connected by perforator veins, which help regulate blood flow. The valves in the veins function by opening only upwards, ensuring that blood flows in one direction: from the lower body towards the heart. However, when these valves become weak or damaged, blood begins to flow backward, leading to the characteristic swelling and twisting of varicose veins.

Causes of Varicose Veins

Varicose veins occur when the veins in the legs become enlarged, twisted, and engorged with blood. This condition can be caused by various factors:

• Age: As we age, the veins lose their elasticity, making it harder for the valves to function properly.
• Genetics: A family history of varicose veins increases your likelihood of developing the condition.
• Prolonged Standing: Standing for long periods of time increases the pressure on the veins, making it harder for blood to flow upwards.
• Pregnancy: Pregnancy increases the volume of blood in the body, and hormonal changes can weaken the veins, leading to varicose veins.
• Obesity: Excess body weight can put additional pressure on the veins, contributing to their enlargement.

Symptoms of Varicose Veins

Varicose veins may be visible on the surface of the skin and can appear swollen, blue or dark purple, and twisted. Other symptoms include:

• Heaviness or aching in the legs
• Swelling around the ankles
• Itching around the veins
• Skin discoloration
• Pain or discomfort after standing for long periods of time

In severe cases, varicose veins can lead to more serious issues like blood clots, ulcers, or bleeding.

Managing and Treating Varicose Veins

While varicose veins are not usually life-threatening, they can cause discomfort and affect your quality of life. Here are some tips to manage and treat varicose veins:

• Compression stockings: These help improve blood circulation and reduce swelling.
• Exercise: Regular physical activity, especially leg exercises, can help improve circulation and reduce the risk of developing varicose veins.
• Elevating the legs: Elevating your legs for 15-20 minutes a few times a day can help improve blood flow and reduce swelling.
• Weight management: Maintaining a healthy weight can reduce the pressure on your veins.
• Avoid prolonged standing: Try to move around or take breaks if you need to stand for long periods of time.

If lifestyle changes and home treatments don’t work, medical procedures like sclerotherapy, laser treatments, or vein stripping may be necessary to treat more severe cases.
