Varicose Veins: Causes, Symptoms and Treatment Options

Varicose veins affect millions of people worldwide and are among the most common vascular conditions. While many people view them as a cosmetic concern, they can actually be a sign of an underlying circulation problem known as chronic venous insufficiency.

Understanding what varicose veins are, why they develop, and when to seek medical attention can help prevent complications and improve long-term vascular health.

Varicose veins are enlarged, twisted veins that become visible beneath the skin. They develop when the valves inside the veins stop functioning properly.

Under normal circumstances, these valves help move blood from the legs back toward the heart. When they become weakened or damaged, blood can pool inside the veins instead of flowing efficiently. This increased pressure causes the veins to enlarge and become more noticeable.

Varicose veins most commonly occur in the legs and feet because these veins must work against gravity to return blood to the heart.

Varicose veins can develop due to a variety of factors that increase pressure within the veins or affect the function of the venous valves.

Common risk factors include:

• Family history of varicose veins or venous disease.
• Standing or sitting for long periods.
• Pregnancy.
• Overweight or obesity.
• Aging.
• Hormonal changes.
• Lack of regular physical activity.
• History of blood clots or deep vein thrombosis (DVT).

When several of these factors are present, the risk of developing chronic venous disease increases significantly.

In addition to their visible appearance, varicose veins can cause symptoms that affect comfort and quality of life.

Common symptoms include:

• Heaviness in the legs.
• Aching or throbbing pain.
• Burning sensations.
• Swelling in the ankles and legs.
• Nighttime leg cramps.
• Itching around the affected veins.
• Leg fatigue.
• Skin discoloration.

As venous disease progresses, more serious symptoms may develop, including:

• Hardening of the skin.
• Darkening of the skin around the ankles.
• Venous stasis dermatitis.
• Bleeding from a varicose vein.
• Venous ulcers that are difficult to heal.

These symptoms may indicate advanced venous insufficiency and should be evaluated by a vascular specialist.

It is recommended to schedule an evaluation if you experience persistent symptoms or noticeable changes in your legs.

You should seek medical attention if you have:

• Ongoing leg pain or heaviness.
• Frequent swelling of the legs or ankles.
• Prominent or bulging veins.
• Changes in skin color or texture.
• Persistent itching.
• Slow-healing wounds or ulcers.
• A family history of venous disease.

Early diagnosis can help prevent complications and improve treatment outcomes.

Diagnosis begins with a medical history review and physical examination.

To evaluate blood flow and identify vein abnormalities, a vascular specialist may recommend a venous Doppler ultrasound.

This noninvasive imaging study allows physicians to visualize blood flow in real time, assess valve function, and identify venous reflux or other circulation problems.

A Doppler ultrasound is considered the gold standard for diagnosing chronic venous insufficiency and varicose veins.

Treatment depends on the severity of symptoms, the size of the affected veins, and the overall condition of the venous system.

Many patients benefit from conservative measures such as:

• Maintaining a healthy weight.
• Walking regularly.
• Avoiding prolonged sitting or standing.
• Elevating the legs when resting.

Compression stockings help improve blood flow and reduce symptoms such as swelling, discomfort, and leg fatigue.

Sclerotherapy involves injecting a specialized solution into the affected vein, causing it to close and gradually fade from view.

These minimally invasive procedures use thermal energy to seal diseased veins and redirect blood flow to healthier veins.

They typically offer shorter recovery times than traditional surgery.

In advanced cases, surgical treatment may be recommended to address larger or more complex varicose veins.

A vascular specialist can determine the most appropriate treatment based on each patient's condition and goals.

Although not all cases can be prevented, certain lifestyle habits may help reduce the risk of developing varicose veins and chronic venous disease.

Helpful preventive measures include:

• Staying physically active.
• Maintaining a healthy weight.
• Avoiding long periods of sitting or standing.
• Elevating your legs periodically.
• Wearing compression stockings when recommended.
• Staying hydrated.
• Avoiding tobacco use.

These habits support healthy circulation and reduce pressure within the veins of the legs.

Varicose veins are more than a cosmetic concern. They may be a sign of chronic venous insufficiency and should not be ignored.

A timely evaluation by a vascular specialist can help identify the cause of your symptoms and determine the most effective treatment plan before complications develop.

Varicose veins are not always dangerous, but they can worsen over time and lead to complications such as inflammation, skin changes, bleeding, or venous ulcers if left untreated.

No. Once a vein becomes varicose, it typically does not disappear without treatment. However, several medical treatments can improve symptoms and appearance.

No. Although the risk increases with age, younger adults can also develop varicose veins due to genetics, hormonal factors, pregnancy, or prolonged standing.

Yes. Activities such as walking, swimming, and cycling help improve circulation and support healthy blood flow in the legs.

The best treatment depends on the severity of venous disease, symptoms, and ultrasound findings. A vascular specialist can recommend the most appropriate option for each patient.

Varicose veins are typically diagnosed and treated by an Angiology and Vascular Surgery specialist or a physician with expertise in vascular medicine.
