What Causes Varicose Veins? Risk Factors, Symptoms & Treatment

Varicose veins are enlarged, twisted veins that most commonly appear on the legs. They develop when the valves inside the veins do not work properly, allowing blood to flow backward and collect in the veins. While some people may be concerned mainly about their appearance, varicose veins can also cause aching, heaviness, swelling, itching, and other discomfort.

The condition is common and may become more noticeable with age. Understanding what contributes to varicose veins and knowing when treatment may be necessary can help people seek appropriate medical evaluation.

What Causes Varicose Veins?

Healthy leg veins contain valves that help blood move upward toward the heart. When these valves become weak or damaged, blood can flow backward and accumulate inside the veins. Increased pressure can cause the veins to enlarge and become twisted or prominent beneath the skin.

Several factors can contribute to the development of varicose veins, including:

• Increasing age

• Family history of vein problems

• Pregnancy and hormonal changes

• Being overweight or obese

• Standing or sitting for prolonged periods

• Lack of regular physical activity

• Previous leg injury or vein problems

People whose work requires them to stand for many hours, such as teachers, healthcare workers, retail employees, and factory workers, may experience increased pressure on the veins of the legs.

What Are the Common Symptoms?

The appearance of enlarged blue, purple, or twisted veins is often the most noticeable sign. However, varicose veins symptoms can involve more than visible changes.

Common problems may include:

• Aching or throbbing in the legs

• A feeling of heaviness or tiredness

• Swelling around the ankles or lower legs

• Burning or itching around affected veins

• Night-time leg cramps

• Discomfort that becomes worse after prolonged standing or sitting

• Skin changes around the ankles in more advanced cases

Some people have visible varicose veins without significant discomfort, while others may experience symptoms that interfere with daily activities.

When Do Varicose Veins Need Treatment?

Not every person with visible varicose veins requires an invasive procedure. Mild cases may initially be managed with lifestyle measures, especially when there are no significant symptoms.

However, medical assessment is advisable when persistent pain, swelling, skin changes, bleeding, or non-healing wounds develop. A specialist can determine whether the veins are causing an underlying circulation problem and whether intervention is appropriate.

If symptoms continue despite conservative measures, varicose veins treatment may be recommended based on the affected veins, severity of the condition, and overall health.

How Are Varicose Veins Diagnosed?

Diagnosis usually begins with a physical examination and discussion of symptoms and medical history. The legs may be examined while standing because this can make enlarged veins easier to identify.

A Duplex Doppler ultrasound is commonly used to assess blood flow through the veins and check whether the valves are functioning properly. It can also help identify blockages or other abnormalities.

Accurate assessment is important because treatment should be selected according to the underlying vein problem rather than appearance alone.

What Are the Treatment Options?

The appropriate varicose veins treatment depends on the severity of symptoms and the condition of the affected veins.

Lifestyle and Conservative Measures

For mild cases, a healthcare professional may recommend measures such as:

• Regular walking and physical activity

• Avoiding prolonged sitting or standing

• Elevating the legs when resting

• Maintaining a healthy body weight

• Wearing compression stockings when medically recommended

These measures may help improve circulation and relieve symptoms, although they do not necessarily eliminate existing enlarged veins.

Laser Treatment

Laser treatment for varicose veins, such as Endovenous Laser Treatment (EVLT), is a minimally invasive procedure in which a laser fiber is introduced into the affected vein to close it. Blood can then be redirected through healthier veins.

SCI International Hospital lists EVLT among its treatment options and states that minimally invasive techniques can involve smaller punctures than traditional open procedures.

Radiofrequency Ablation

Radiofrequency ablation uses controlled heat to close an affected vein. It is another minimally invasive approach that may be considered depending on the patient's vein anatomy and clinical findings.

Sclerotherapy

Sclerotherapy involves injecting a medical solution into selected veins, causing them to close gradually. It may be suitable for certain smaller varicose veins or spider veins.

Surgical Treatment

In more advanced or complex cases, varicose vein surgery may be considered. The appropriate procedure depends on the veins involved and whether minimally invasive options are suitable.

A vascular or general surgeon can explain the available approaches after evaluating the patient's condition.

What Is the Recovery Like?

Recovery depends on the treatment used. Minimally invasive procedures may allow many patients to return to normal activities relatively quickly, although the exact recovery period varies.

Mild bruising, swelling, or discomfort can occur after treatment. Walking is often encouraged because movement supports healthy blood circulation, but patients should follow their doctor's specific instructions regarding exercise and other activities.

Why Choose SCI International Hospital?

For people seeking varicose veins treatment in Delhi, SCI International Hospital provides evaluation and treatment through its General Surgery services. The hospital's dedicated varicose-vein treatment information describes the use of Doppler ultrasound for assessment and lists minimally invasive options such as EVLT and radiofrequency ablation, along with sclerotherapy and surgical treatment where appropriate.

Treatment is selected according to factors such as symptoms, vein involvement, overall health, and the severity of the condition. Patients can discuss their diagnosis, available treatment approaches, expected recovery, and potential risks with the appropriate specialist before making a treatment decision.

Conclusion

Varicose veins develop when weakened or damaged vein valves allow blood to collect in the veins, causing them to become enlarged and twisted. Age, family history, pregnancy, excess weight, prolonged standing or sitting, and physical inactivity can increase the likelihood of developing them.

While mild cases may be managed with lifestyle measures, persistent pain, swelling, skin changes, bleeding, or ulcers may require medical evaluation. Depending on the condition, treatment can include conservative measures, laser treatment, radiofrequency ablation, sclerotherapy, or surgery. Early assessment can help identify the underlying vein problem and determine the most appropriate treatment approach.
