Varicose veins are swollen, twisted veins that most commonly appear in the legs.
Varicose veins usually appear as blue or purple bulges in your legs, feet, and ankles. Smaller red or purple lines, called spider veins, may surround varicose veins.
Varicose veins are very common. While they are often seen as a cosmetic issue, varicose veins can cause significant discomfort and lead to more serious health problems if left untreated.
Understanding varicose veins can help you make decisions about treatment and your overall health. Learn more about varicose veins, including their definition, causes, symptoms, diagnosis, treatment, and potential risks and complications.

What are varicose veins?
Varicose veins are enlarged veins that appear swollen and twisted, usually developing in the legs and visible through the skin. They occur when the one-way valves in the veins weaken or become damaged, causing blood to pool and the veins to stretch and become varicose.
What causes varicose veins?
Varicose veins develop due to malfunctioning valves in the veins that prevent blood from flowing backward. When these valves fail, blood pools in the veins, causing them to enlarge.
Over time, vein walls can lose elasticity, contributing to the development of varicose veins.
Risk factors
- Age: The risk of varicose veins increases with age due to wear and tear on vein valves.
- Gender: Women are more likely to develop varicose veins, partly due to hormonal changes during pregnancy, menstruation, and menopause.
- Family history: A genetic predisposition to varicose veins increases the risk for certain individuals.
- Obesity: Excess weight adds pressure on veins, increasing the likelihood of varicose veins.
- Prolonged standing or sitting: Occupations that require long periods of standing or sitting can contribute to the development of varicose veins by limiting blood flow.
Other contributing factors
- Pregnancy: Pregnancy increases blood volume and decreases blood flow from the legs to the pelvis, contributing to varicose veins.
- Hormonal changes: Hormonal fluctuations associated with pregnancy, menopause, and birth control pills can increase the risk.
- Sun exposure: Excessive sun exposure, especially on fair skin, can cause varicose veins, particularly on the face.
Symptoms of varicose veins
Common symptoms
- Visible veins: Twisted, swollen veins visible just under the skin’s surface.
- Aching and discomfort: Painful, heavy, or aching sensations in the legs, often worsening after standing or sitting for long periods.
- Swelling: Swelling in the lower legs and ankles.
- Throbbing and cramping: Throbbing, burning, or muscle cramping in the legs.
- Skin changes: Changes in skin color, itching, and ulceration near the ankle.
Severe symptoms
- Venous ulcers: Painful sores that develop near varicose veins, typically around the ankles, due to prolonged pressure and poor blood flow.
- Bleeding veins: Varicose veins close to the skin may rupture and result in minor bleeding.
- Thrombophlebitis: Inflammation and clotting in varicose veins, causing pain and redness.
Diagnosis of varicose veins
Medical history and physical examination
- Symptom assessment: Detailed inquiry about the presence, duration, and severity of symptoms such as visible veins, pain, and swelling.
- Physical examination: Visual inspection and palpation of the legs to evaluate the extent of varicose veins and associated symptoms.
Diagnostic tests
- Doppler ultrasound: A non-invasive test using sound waves to assess blood flow in the veins and identify any valve problems or blood clots.
- Duplex ultrasound: Combines traditional and Doppler ultrasound to provide detailed images of veins, measuring blood flow and visualizing the structure of veins.
Treatment of varicose veins
Lifestyle modifications
- Exercise: Regular physical activity to improve circulation and vein strength.
- Weight management: Maintaining a healthy weight to reduce pressure on the veins.
- Elevating the legs: Elevating the legs when resting to reduce swelling and improve blood flow.
- Avoid prolonged standing or sitting: Taking breaks to move around and flex the legs to enhance blood circulation.
Compression therapy
- Compression stockings: Specially designed stockings that apply gentle pressure to the legs, promoting blood flow and reducing swelling and discomfort.
Medical procedures
- Sclerotherapy: Injection of a solution into the varicose veins, causing them to collapse and be reabsorbed by the body.
- Endovenous laser treatment (EVLT): A minimally invasive procedure using laser energy to close off varicose veins.
- Radiofrequency ablation (RFA): A procedure using radiofrequency energy to heat and seal off varicose veins.
- Ambulatory phlebectomy: Removal of smaller varicose veins through tiny incisions in the skin.
Surgical treatment
- Vein stripping and ligation: Traditional surgery involving the removal of the affected vein through small incisions.
- Endoscopic vein surgery: Used for advanced cases with leg ulcers, this procedure involves inserting a thin camera into the vein to guide the surgical removal of the affected veins.
Potential risks and complications
Complications of untreated varicose veins
- Venous ulcers: Chronic sores that take a long time to heal and are prone to infection.
- Deep vein thrombosis (DVT): Formation of blood clots in deeper veins, which can be dangerous if the clot travels to the lungs (pulmonary embolism).
- Chronic venous insufficiency: Long-term condition that results from impaired blood flow, leading to severe leg swelling, pain, and skin changes.
Treatment risks
- Infection: Risk of infection at the injection site or surgical site.
- Bleeding and bruising: Minor bleeding or bruising associated with procedures.
- Nerve damage: Possible damage to surrounding nerves during vein removal or ablation procedures.
Long-term complications
- Recurrence: Varicose veins may return after treatment, particularly if underlying risk factors are not managed.
- Side effects of treatments: Potential side effects from sclerotherapy or other procedures, such as skin discoloration or irritation.
Varicose veins are a common condition that can cause discomfort and lead to more serious health issues if not addressed. Understanding the causes, symptoms, diagnostic methods, and treatment options is essential for effective management. If you or a loved one are experiencing symptoms of varicose veins, consulting with a health care provider will help develop a comprehensive treatment plan tailored to your specific needs and circumstances.
