Varicose veins (also known as varicosities) are a common condition affecting millions of people in the UK, typically, at least one in three people will encounter varicose veins in their lifetime.

What Are Varicose Veins (And How to Spot Them)?

Varicose veins are swollen veins that usually appear on the legs. They develop when the valves within the veins fail to function properly, causing blood to pool rather than flow back toward the heart. This underlying cause, known as venous insufficiency or reflux, can lead to symptoms such as aching, swelling, and visible bulging veins.

 

Key Characteristics of Varicose Veins

It’s natural to wonder how to spot varicose veins. Here are three common signs:

  • Enlarged and twisted veins
  • Often appear blue or dark purple
  • Most commonly found on legs and feet

    Symptoms of Varicose Veins

    Recognising the symptoms early can help in seeking timely treatment. Common symptoms include:

    • Aching, heavy legs
    • Swelling in the ankles or feet
    • Burning or throbbing sensations in the legs
    • Dry or itchy skin over the affected veins
    • Muscle cramps, particularly at night

    What Causes Varicose Veins?

    Varicose veins are primarily triggered by underlying causes – specifically weakened vein walls and faulty valves. Contributing factors include:

    • Genetics: A family history of varicose veins increases your likelihood of developing them.
    • Age: Vein elasticity decreases over time, making older adults more susceptible.
    • Pregnancy: Hormonal changes and increased blood volume can put extra pressure on veins (get more information about varicose veins during pregnancy).
    • Lifestyle: Prolonged standing or sitting and lack of physical activity can exacerbate the condition.

    Where Do Varicose Veins Appear?

    Varicose veins can develop in several areas of the body, though they most commonly affect:

    Legs and Feet:

    The increased pressure in veins due to standing or walking makes these areas the most susceptible.


    Pelvic Region:

    Women may develop varicose veins in the pelvic area, particularly during or after pregnancy.

    Varicose Veins Diagnosis

    The only way to accurately determine the underlying cause of your varicose veins is by having a colour duplex ultrasound scan performed on your legs. Without this full and detailed scan, it is impossible to properly assess your veins or determine the exact treatment you require.


    What to Expect from Your Consultation

    We believe it’s important for you to meet your consultant right from your first appointment. Your consultation lasts around 30 minutes and includes a detailed colour duplex ultrasound scan to assess the underlying cause of your vein concerns. 

    In most cases, varicose veins develop due to faulty valves in the leg veins, causing blood to flow in the wrong direction. This ‘reflux’ can lead to the lumps and bumps of varicose veins, as well as symptoms like aching, pain, and restless legs. Your consultant will explain everything clearly and provide a personalised treatment plan tailored to your needs.

    The best person to undertake the scan is the person who will carry out your treatment. Ensuring that you have your initial meeting with a dedicated vascular consultant is something that we pride ourselves on at Veincentre. Being able to build a rapport, and hear first-hand the wealth of expertise that our consultants have, is priceless and gives you immediate peace of mind.

      At a Glance: Veincentre FAQs

      Do varicose veins hurt?

      Yes, varicose veins can cause discomfort, including aching, throbbing, and a feeling of heaviness in the legs. In some cases, they may also result in cramps or itching around the affected area.

      What happens if varicose veins go untreated?

      If left untreated, varicose veins can worsen over time, leading to complications such as skin damage, ulcers, and an increased risk of blood clots. Early treatment can help prevent these issues and improve your quality of life.

      Are there any effective home remedies to prevent varicose veins?

      While certain lifestyle changes, such as regular exercise, maintaining a healthy weight, and elevating your legs, can improve vein health, home remedies alone cannot treat varicose veins. Professional medical treatments are required to address the underlying causes effectively.

      How are varicose veins treated?

      Veincentre offers minimally invasive treatments like Endovenous Laser Ablation (EVLA), and Foam Sclerotherapy. These procedures are quick, effective, and performed under local anaesthetic.

      Can varicose veins reoccur after treatment?

      While treatment is highly effective (EVLA has a 99% success rate), new varicose veins can develop over time due to factors like genetics or lifestyle. 

      Are varicose veins purely cosmetic?

      No, varicose veins are more than just a cosmetic concern. They can sometimes cause discomfort and other symptoms. While they may not always lead to complications, seeking treatment can help improve both your comfort and overall vein health.

      At what age do varicose veins occur?

      Varicose veins can occur at any age. It does tend to happen with older patients, but we do see patients presenting in their 20s with varicose veins as well.

      How can I slow the progression of my varicose veins?

      To limit the progression of varicose veins, you could make a few lifestyle adjustments. Do sensible things like exercising and eating healthily. If you smoke, try to reduce or cut out as much as possible, and also reduce alcohol intake.
