What Causes Varicose Veins? Causes, Symptoms & Advanced Treatment for Healthy Legs

Introduction

Do you notice bulging blue or purple veins on your legs? Do your legs feel heavy, swollen, or painful after standing for a long time? These may be signs of varicose veins.

Many people think varicose veins are only a cosmetic problem, but they can also cause discomfort and lead to complications if left untreated. Understanding the causes of varicose veins can help you seek treatment early and protect your vein health.

At our hospital, Dr. Naveen Kumar Anem, MBBS, DNB (General Surgery), FMAS, FIAGES, Laparoscopic & GI Surgeon, offers comprehensive evaluation and advanced treatment options for varicose veins, including minimally invasive procedures when appropriate.

What Are Varicose Veins?

Varicose veins are enlarged, twisted veins that usually appear on the legs and feet. They develop when the tiny valves inside the veins become weak or damaged. Instead of flowing smoothly back to the heart, blood collects inside the veins, causing them to swell and become visible.

Although anyone can develop varicose veins, they are more common in adults, especially women, older individuals, and people who spend long hours standing or sitting.

Symptoms of Varicose Veins

Some people have only visible veins, while others experience uncomfortable symptoms.

Common symptoms include:

• Bulging blue or purple veins
• Heavy or tired legs
• Aching or throbbing pain
• Swelling around the ankles
• Burning or itching over the veins
• Muscle cramps, especially at night
• Leg discomfort after standing for long periods
• Skin discoloration around the ankles
• Restless legs in some individuals

If symptoms become severe or the skin develops sores or ulcers, prompt medical evaluation is important.

What Causes Varicose Veins?

Several factors can increase the risk of developing varicose veins.

1. Weak or Damaged Vein Valves

Healthy veins contain tiny valves that keep blood flowing toward the heart. When these valves weaken, blood flows backward and collects in the veins, causing them to enlarge.

2. Ageing

As people grow older, veins naturally lose some of their elasticity. This makes it easier for vein valves to become less effective.

3. Family History

If close family members have varicose veins, your chances of developing the condition are higher.

4. Standing or Sitting for Long Hours

Teachers, healthcare workers, factory employees, office workers, and others who remain in one position for extended periods may have a higher risk because blood circulation slows in the legs.

5. Pregnancy

During pregnancy, blood volume increases and hormonal changes relax vein walls. These changes can contribute to varicose veins, which often improve after delivery but may persist in some women.

6. Excess Body Weight

Being overweight places additional pressure on the leg veins, making it more difficult for blood to return to the heart.

7. Lack of Physical Activity

Regular walking and exercise help the calf muscles pump blood upward. A sedentary lifestyle can reduce this natural pumping action.

How Are Varicose Veins Diagnosed?

A thorough evaluation helps determine the severity of the condition and guides treatment.

Diagnosis may include:

• Medical history
• Physical examination while standing
• Assessment of symptoms
• Duplex Doppler Ultrasound to evaluate blood flow and identify faulty veins

Ultrasound is painless and helps your doctor plan the most suitable treatment.

Treatment for Varicose Veins

The best treatment depends on the size of the veins, your symptoms, and the results of your ultrasound scan. Mild cases may improve with lifestyle changes, while larger or painful varicose veins may need medical procedures.

Your treatment plan is always personalized after a complete evaluation.

Lifestyle Changes

Lifestyle changes cannot remove existing varicose veins, but they can help reduce symptoms and slow the progression of the disease.

Your doctor may recommend:

• Walking for at least 30 minutes most days.

• Maintaining a healthy body weight.

• Avoiding standing or sitting in one position for long periods.

• Elevating your legs whenever possible.

• Wearing properly fitted compression stockings if advised.

• Staying physically active to improve blood circulation.

Compression Stockings

Compression stockings gently squeeze the legs to improve blood flow back to the heart. They may reduce swelling, aching, and heaviness.

They are often recommended:

• In the early stages of varicose veins.

• During pregnancy.

• After certain vein procedures.

• For people who are not suitable candidates for surgery.

Endovenous Laser Treatment (EVLT)

Endovenous Laser Treatment (EVLT) is one of the most advanced treatments for varicose veins.

During this minimally invasive procedure, a thin laser fiber is inserted into the affected vein using ultrasound guidance. The laser heats and seals the unhealthy vein, allowing blood to flow through healthier veins instead.

Benefits of EVLT

• Minimally invasive procedure.

• Small puncture instead of large surgical cuts.

• Less pain after treatment.

• Minimal scarring.

• Quick recovery.

• Usually performed as a day-care procedure.

• Early return to normal daily activities.

Radiofrequency Ablation (RFA)

Another modern treatment is Radiofrequency Ablation (RFA). Instead of laser energy, controlled heat from radiofrequency energy is used to close the damaged vein.

Both EVLT and RFA are effective options. Your doctor will recommend the most appropriate treatment based on your condition.

Sclerotherapy

For smaller varicose veins and spider veins, sclerotherapy may be recommended. A special solution is injected into the affected vein, causing it to close gradually. The body naturally absorbs the treated vein over time.

Surgical Treatment

If varicose veins are very large, recurrent, or unsuitable for minimally invasive procedures, surgery may be considered. The type of surgery depends on the severity of the disease and your overall health.

Your surgeon will explain the recommended approach, expected benefits, and possible risks before treatment.

Recovery After Varicose Vein Treatment

Recovery depends on the treatment performed, but many patients recover quickly after minimally invasive procedures.

During recovery, you may be advised to:

• Walk regularly to improve circulation.

• Wear compression stockings if prescribed.

• Drink enough water.

• Avoid prolonged standing during the initial recovery period.

• Keep follow-up appointments.

• Resume normal activities gradually, as advised by your doctor.

Many patients who undergo EVLT or RFA return to routine activities within a short time, although individual recovery varies.

Possible Complications if Varicose Veins Are Left Untreated

Ignoring varicose veins may increase the risk of complications in some patients.

Possible complications include:

• Persistent leg pain.

• Increasing swelling.

• Skin discoloration.

• Venous eczema.

• Bleeding from enlarged veins.

• Venous ulcers around the ankle.

• Superficial vein inflammation.

• In some cases, blood clots requiring urgent medical evaluation.

Early diagnosis and treatment can help reduce these risks.

Benefits of Early Treatment

Seeking treatment before symptoms become severe offers several advantages.

Benefits include:

• Relief from leg pain and heaviness.

• Reduced swelling.

• Improved blood circulation.

• Better appearance of the legs.

• Lower risk of skin damage and ulcers.

• Improved mobility.

• Better quality of life.

• Greater confidence during daily activities.
