Understanding Varicose Veins: Symptoms, Causes, Diagnosis, and Treatment



What are Varicose Veins?

Varicose veins are swollen and enlarged veins that typically occur in the legs. These veins, located close to the skin's surface, become varicose due to increased pressure, especially from prolonged standing or walking.

What is the Difference Between Varicose Veins and Spider Veins?

Varicose veins appear knobby and twisted and have a darkish-blue hue. Spider veins resemble varicose veins but are smaller and nearer to the skin's surface. They often exhibit red or blue colours and can resemble tree branches or spider webs commonly found on the legs or face.

Who is Likely to Get Varicose Veins?

Varicose veins are prevalent in women, particularly during hormonal shifts like pregnancy and menopause. Moreover, the risk escalates with age but can manifest in adulthood. Certain health conditions, including obesity, Deep Vein Thrombosis (DVT), and familial history, can increase susceptibility. Therefore, it is vital for individuals, especially those with predisposing factors, to maintain wellness and consult medical professionals if symptoms arise.

What are the Symptoms of Varicose Veins?

Common varicose vein symptoms that arise in people are-;

  • Appearance: Veins appear bulging, twisted, and dark purple or blue.
  • Pain: Legs may feel achy, heavy, or sore, particularly behind the knees.
  • Swelling: Legs, ankles, or feet may swell.
  • Skin: Skin colour alterations around the veins, with potential brown discolourations, can be witnessed if untreated.
  • Other symptoms include itching, burning, throbbing, or muscle cramps around the veins, which often worsen at night.
  • Additional indicators: Sores on the legs, rash, dry, itchy, or thin skin over the affected vein.

Where Do Varicose Veins Usually Appear?

Varicose veins, or varicosities, present as swollen, twisted veins, can appear throughout the body. Though these are frequently observed in the legs and feet, some common sites include

  • Calves
  • Thighs
  • Areas both behind and in front of the legs, especially near the ankles and feet
  • During pregnancy, these may appear around the lower pelvic region, inner thigh, and buttocks.

What Causes Varicose Veins?

Varicose veins develop due to weakened or damaged vein walls and valves, which cause blood to pool and veins to become enlarged and twisted. Some other varicose vein causes include:

  • Age: Vein elasticity diminishes with ageing.
  • Pregnancy: Varicose veins in pregnancy occur due to increased blood volume to support the baby's heightening pressure.
  • Overweight: Excess weight adds strain to veins.
  • Prolonged sitting or standing: Extended periods in these positions may elevate risk.
  • Sedentary lifestyle: Lack of activity can contribute to heightened blood pressure.
  • Other factors: Smoking, oral contraceptives, hormone replacement therapy, leg injuries, chronic constipation, and insufficient vitamin K2 levels can also increase susceptibility to varicose veins.

How are Varicose Veins Diagnosed?

A healthcare professional can opt for any of the following varicose veins diagnosis:

  • Physical examination: Your healthcare provider will assess your legs while standing to observe any swelling and examine the appearance of varicose veins.
  • Medical history inquiry: Symptoms, family history, activity levels, and lifestyle are often discussed to understand potential risk factors.
  • Imaging tests: A Duplex Ultrasound (DUS), a non-invasive method that utilises sound waves to evaluate blood flow in leg vessels, may be prescribed. This can help locate damaged valves contributing to varicose veins.
  • Further investigation: If varicose veins cause pain, skin changes, or other complications, a referral to a vascular specialist may be warranted.

What is the Treatment for Varicose Veins?

A few varicose vein treatment options available as temporary or permanent treatments are-;

  • Compression stockings: These garments exert pressure on the legs, aiding blood circulation. They are available over-the-counter or as prescription-strength, and insurance coverage may apply if symptoms are present.
  • Varicose vein surgery procedures
    • Sclerotherapy: Involves injecting a solution into varicose veins to close them. Multiple injections may be necessary, and the procedure can often be performed in the office without anaesthesia.
    • Laser treatment: Uses bursts of light to fade varicose veins. It is a non-invasive procedure without cuts or needles.
    • Catheter-based procedures (radiofrequency or laser energy): These methods involve heating and sealing varicose veins and are particularly effective for larger veins.
    • High ligation and vein stripping: This outpatient procedure ties off and removes varicose veins through small incisions.
    • Ambulatory phlebectomy: Smaller varicose veins are removed through tiny skin pricks, resulting in minimal scarring. This procedure is also performed on an outpatient basis.

What are the Complications/Side Effects of the Treatment?

Possible complications or side effects of varicose vein treatments include:

  • Temporary bruising or discolouration in the treated area
  • Swelling or discomfort may occur
  • Skin irritation or rash could develop
  • Allergic reactions to medications used during procedures are rare but possible
  • Numbness or tingling sensations may be experienced
  • Blood clots can occur, although they are uncommon
  • Infection or nerve damage is rare, but potential risks
  • Varicose veins may recur over time
  • Scarring or changes in skin texture may occur

How Can I Prevent Varicose Veins?

Consider these lifestyle adjustments to prevent varicose veins potentially:

  • Incorporate regular exercise to enhance blood flow and muscle tone. Aim for activities like walking or cycling for 30 minutes 3–5 times per week.
  • Maintain a healthy weight to alleviate pressure on the veins.
  • Adopt a balanced diet low in salt and rich in fibre to mitigate water retention, a factor contributing to varicose veins.
  • Be mindful of your sitting posture; avoid crossing your legs and elevate your legs when seated or lying down.
  • Opt for appropriate footwear, avoiding high heels or tight stockings except for compression stockings.
  • Take breaks to change positions frequently, incorporating stretching or short walks every 30 minutes.

What is the Outlook for People with Varicose Veins?

The outlook for individuals with varicose veins is generally positive. With appropriate management, including lifestyle adjustments and medical interventions as necessary, most people can effectively control symptoms and minimise complications. However, regular monitoring is essential to prevent potential worsening or complications.

What are the complications of varicose veins?

Potential complications of varicose veins include:

  • Ulcers: Painful sores may develop near varicose veins, particularly around the ankles.
  • Blood clots: Enlarged veins deep within the legs can lead to clot formation.
  • Bleeding: In rare instances, superficial veins may rupture.
  • Leg swelling: Prolonged varicose veins can result in swelling of the legs.

Do varicose veins return after treatment?

Varicose veins can indeed recur after treatment, with approximately 60% of individuals experiencing a reappearance within five years.


Varicose veins are common and can recur even after permanent varicose vein treatment. However, with proper management and lifestyle adjustments, individuals can often control varicose vein symptoms and minimise complications. Remember, regular monitoring is key to maintaining vein health.
