What Do You Know About Varicose Veins?
Varicose veins are swollen, twisted veins that you can often see just under the skin, usually on the legs and feet. They happen when the small valves inside the veins stop working properly. Normally, these valves keep blood flowing up toward the heart. When they fail, blood begins to pool, and this causes the veins to enlarge and become visible. This condition is a common sign of chronic venous insufficiency. For many people, varicose veins are mainly a cosmetic concern, but they can also cause aching, throbbing pain, heaviness in the legs, and muscle cramps. If left untreated, they can sometimes lead to more serious skin problems or ulcers.
How Do Varicose Veins Develop?
Varicose veins develop when there is increased pressure in the veins, causing damage to the tiny, one-way valves inside them. These valves are essential for pushing blood back up to the heart, working against gravity, especially in the legs. When the valves weaken or become damaged, they can't close properly, which allows blood to flow backward and pool in the vein. This pooling causes the vein to swell, stretch, and become a visibly twisted and bulging varicose vein. The condition is fundamentally a problem of chronic venous insufficiency.
The development of varicose veins is complex and usually involves a combination of factors. The most significant cause is heredity, as a family history of the condition suggests an inherited weakness in the vein walls or valves. While diet alone isn't a direct cause, an unhealthy diet that leads to obesity can contribute significantly, as excess weight places greater pressure on the leg veins. Similarly, malnutrition is not a primary cause, but a deficiency in certain vitamins could potentially affect blood vessel health. Other major risk factors that worsen the condition include:
- Pregnancy (due to increased blood volume and pressure)
- Jobs or lifestyles that involve prolonged standing or sitting
All this makes it harder for blood to flow back to the heart.
Types of Varicose Veins
There are several types of varicose veins, and while many are treated by a vascular specialist (like a phlebologist or vascular surgeon), the specific doctor may depend on the type and severity of the condition. The types of varicose veins are generally defined by their size, location, and appearance:
- Truncal Varicose Veins: large, prominent, bulging veins appear on the thighs and calves. This type often causes more severe symptoms, like pain and aching.
- Reticular Veins: smaller (about 2-3 millimeters in diameter), usually red or blue, appear in a network or web-like pattern and are found behind the knees.
- Spider Veins (Telangiectasias): smallest type, appearing as thin, wispy red or blue lines, resembling a spiderweb or tree branches. Do not typically cause pain or lead to serious health problems. Appear on the legs, face, or other areas.
Most types of varicose veins are treated by the same core specialists, namely a Phlebologist (a doctor who specializes in vein diseases) or a Vascular Surgeon.
What Causes Varicose Veins?
Veins have one-way valves that open to allow blood to flow toward the heart and then close to prevent it from flowing backward, especially in the legs, where blood must work against gravity. When these valves don't close properly, blood can pool in the vein, causing it to enlarge, swell, and twist, which results in a varicose vein. Several factors can increase the risk of developing varicose veins:
- Having close family members with varicose veins
- Women are more likely to develop them, often because of hormonal changes during puberty, pregnancy, or menopause.
- Being overweight adds pressure on the leg veins.
- Lack of movement makes it harder for the leg muscles to pump blood back to the heart, which increases pressure and causes blood to pool in the veins.
Varicose Veins Symptoms and Early Signs
The signs and symptoms of varicose veins range from purely visible cosmetic changes to significant discomfort, which often worsens after long periods of standing or at the end of the day. The key signs and symptoms include:
- Itching, dry, thin, and scaly skin over the affected vein
- An uncomfortable sensation in the legs that creates an urge to constantly move them, often coinciding with Restless Leg Syndrome (RLS).
How Can Varicose Veins Be Diagnosed?
The diagnosis of varicose veins is primarily clinical, meaning a specialist can often identify them through a physical examination. Still, advanced tools are essential to confirm the cause and plan treatment. The main diagnostic tool is the Duplex Ultrasound, a non-invasive test that uses sound waves to create images of your veins and evaluate blood flow.
- Physical Examination: The doctor inspects the legs while you are standing to note any visible varicose veins, swelling, skin changes, and areas of tenderness.
- Duplex Ultrasound: This is the most critical test. It determines if there is venous reflux (backward blood flow) caused by faulty valves and maps the entire venous structure (both superficial and deep veins) to pinpoint the exact source of the problem.
Generally, you do not need to be empty stomach (fast) for a leg vein Duplex Ultrasound, as the digestive process does not interfere with the blood flow in the leg veins. You can usually eat and drink normally before the test.
Treatment of Varicose Veins
When it comes to addressing varicose veins, several effective treatment options are available. Understanding these procedures can help you make informed decisions about your care and what you can expect from the process.
Endovenous Thermal Ablation (EVTA)
This is a minimally invasive, in-office procedure, typically performed under local anesthesia. The specialist uses ultrasound guidance to insert a thin catheter (tube) into the affected vein, usually through a tiny incision below the knee. A laser fiber or radiofrequency electrode at the tip of the catheter is activated to heat the vein wall from the inside. As the catheter is slowly withdrawn, the heat seals the entire length of the faulty vein, causing it to collapse. Blood flow is immediately redirected to healthy veins.
Sclerotherapy (Liquid or Foam)
The specialist injects a sclerosant solution (either liquid or mixed with air to create foam) directly into the affected vein using a very fine needle. The solution irritates the lining of the vein, causing it to swell, collapse, and seal shut. The vein then turns into scar tissue, which the body eventually reabsorbs. The procedure is done in the office and does not require anesthesia.
Ambulatory Phlebectomy (Microphlebectomy)
This is a minimally invasive technique performed under local anesthesia. The specialist makes a series of tiny, slit-like incisions (2-3 mm) directly over the bulging vein. A special hook is then inserted through these incisions to remove the segments of the varicose vein physically. The incisions are so small that they usually do not require stitches and heal with minimal to no scarring.

Frequently Asked Questions
Are varicose veins swollen veins located in the legs?
Yes. Varicose veins are visibly swollen, enlarged, and often twisted veins that appear just beneath the surface of the skin, most commonly in the legs, feet, and ankles.
Can prolonged standing or leg crossing lead to varicose veins?
Prolonged standing is a known risk factor, as it increases pressure in the leg veins, which can weaken the vein walls and valves over time. However, crossing your legs while sitting is generally considered an old wives' tale and is not scientifically supported as a cause of varicose veins.
Is there a connection between pregnancy and the development of varicose veins?
Yes. Pregnancy is a significant risk factor. The increased blood volume in the body and the pressure exerted by the growing uterus on the veins in the pelvis can lead to the development or worsening of varicose veins. The hormonal changes during pregnancy can also relax the vascular walls. Varicose veins often improve or resolve within a few months after delivery.
How can I determine my risk of developing varicose veins?
Your risk is determined by several factors, including:
- Family History
- Age
- Sex
- Weight
- Lifestyle
Since varicose veins are primarily cosmetic issues, do they need treatment?
Varicose veins are not always just a cosmetic issue. While some people seek treatment solely for appearance, varicose veins can cause symptoms like aching, throbbing, cramping, heaviness, itching, and swelling. More seriously, if left untreated, they can lead to health complications such as skin changes, chronic sores (ulcers), or blood clots (superficial or deep vein thrombosis - DVT). Treatment is often needed to ease symptoms, prevent complications, or for cosmetic reasons.
What steps can I take to avoid developing varicose veins?
While you cannot prevent varicose veins entirely, especially if you have a genetic predisposition, you can significantly reduce your risk and manage symptoms by exercising regularly, elevating your legs, wearing compression stockings, avoiding tight clothing, etc.
