Managing Varicose Veins: A clinical perspective for local mothers

Understanding Varicose Veins: More Than Just a Cosmetic Concern

For many mothers in Singapore, life is a constant balance of managing family, career, and personal wellbeing. Amidst this busy schedule, it is common to notice physical changes, including the appearance of bluish, bulging veins on the legs. Often dismissed as a simple cosmetic issue or an inevitable part of ageing or motherhood, varicose veins are in fact a sign of an underlying medical condition known as chronic venous insufficiency. Understanding the mechanics of this condition is the first step toward effective management and relief.

What Happens Inside Your Veins?

Your circulatory system is an intricate network. While arteries carry oxygen-rich blood from the heart to the rest of your body, veins have the challenging task of returning that blood to the heart, often working against gravity. To accomplish this, veins in your legs are equipped with tiny, one-way valves that open to allow blood to flow upward and then snap shut to prevent it from flowing back down. You can think of them as a series of one-way gates along a highway.

Chronic venous insufficiency occurs when these valves weaken or become damaged. When a valve fails, it no longer closes properly, allowing blood to leak backward and pool in the lower part of the vein. This process is called venous reflux. Over time, the constant pressure from this pooled blood causes the vein walls to stretch, enlarge, and become distorted. The result is the visible, rope-like varicose vein. This is not just a surface-level problem; it reflects a breakdown in the fundamental mechanics of your circulatory system.

Why Are Mothers More Susceptible?

Pregnancy is a significant catalyst for the development of varicose veins, and several physiological factors are at play. First, hormonal changes, particularly the surge in progesterone, cause the walls of your veins to relax and become more flexible. While essential for accommodating a growing baby, this relaxation can also affect the veins in your legs, making them more prone to stretching and valve failure.

Second, a woman’s total blood volume increases substantially during pregnancy to support the fetus. This adds to the overall burden on the circulatory system. Third, as the uterus expands, it exerts direct physical pressure on the large veins in the pelvis, such as the inferior vena cava. This pressure increases resistance and makes it even harder for blood to travel up from the legs, causing it to back up and increase pressure in the leg veins. While some pregnancy-related varicose veins may improve after delivery, the underlying weakness in the vein walls and valves can persist, making a recurrence more likely with subsequent pregnancies or later in life. Furthermore, a family history of varicose veins strongly indicates a genetic predisposition, meaning the structural integrity of your veins may be inherently weaker.

Recognising the Symptoms and Seeking a Diagnosis

The visual appearance of a varicose vein is its most obvious characteristic, but the symptoms extend far beyond what is visible. Paying attention to what your legs are feeling is crucial for early detection and preventing complications. The symptoms are often a direct result of the increased pressure and inflammation within the affected veins, a condition known as chronic venous hypertension.

Early Signs and Symptoms to Watch For

Many individuals experience physical discomfort long before the veins become prominently visible. These symptoms can significantly impact your quality of life. Common complaints include:

• A persistent aching or heavy feeling in the legs, especially after long periods of standing or sitting.
• Throbbing, burning, or a cramping sensation in the muscles.
• Swelling, medically known as edema, in the feet and ankles that typically worsens as the day progresses.
• Itchy skin over the affected veins, which is a sign of venous eczema or stasis dermatitis.
• Restless legs syndrome, an uncontrollable urge to move the legs, particularly at night.

In Singapore’s warm and humid climate, these symptoms can feel more pronounced as heat can cause veins to dilate further, exacerbating the pooling of blood. It is important to recognise these signs not as normal fatigue but as potential indicators of venous insufficiency that warrant further attention.

The Diagnostic Process in Singapore

If you experience any of the symptoms above, or if you are concerned about the appearance of your veins, the first step is to consult a General Practitioner (GP). Your GP can perform an initial assessment and, if necessary, provide a referral to a specialist, typically a vascular surgeon, who focuses on diseases of the circulatory system.

The specialist will conduct a thorough physical examination, assessing your legs in both sitting and standing positions to check for visible signs of venous disease. They will ask about your medical history, family history, and specific symptoms. However, the gold standard for diagnosing varicose veins and determining the extent of the underlying problem is a Duplex Ultrasound scan. This is a non-invasive, painless imaging test that uses sound waves to create a map of your veins. It allows the clinician to visualise the structure of your veins, check the function of the valves, and pinpoint the exact locations of venous reflux. This detailed information is critical for creating an effective and personalised treatment plan.

Conservative Management: Practical Steps for Daily Life

Before considering medical procedures, the management of varicose veins begins with conservative, lifestyle-based strategies. These foundational steps are designed to alleviate symptoms, slow the progression of the condition, and improve your overall venous health. For many individuals with mild to moderate varicose veins, these measures can provide significant relief and are essential components of any long-term management plan.

The Foundation of Management: Lifestyle Adjustments

Simple, consistent changes to your daily routine can make a substantial difference. Regular physical activity is paramount. Low-impact exercises like brisk walking, swimming, or cycling are particularly beneficial. These activities engage your calf muscles, which act as a powerful secondary pump. Each time your calf muscle contracts, it squeezes the deep veins in your legs, propelling blood upward toward the heart and reducing venous pressure.

Leg elevation is another simple yet highly effective technique. By raising your legs above the level of your heart for 15 to 20 minutes, two to three times a day, you use gravity to help drain the pooled blood from your lower legs. This can immediately reduce swelling and feelings of heaviness. For diet, focusing on fibre-rich foods helps prevent constipation, as straining can increase abdominal pressure and worsen venous reflux. Additionally, incorporating foods rich in flavonoids, such as berries, citrus fruits, and leafy greens, can help improve venous tone and reduce inflammation.

Compression Therapy: A Cornerstone of Treatment

Medical-grade compression stockings are a non-invasive and highly effective tool for managing varicose vein symptoms. Unlike regular socks or hosiery, these garments are specifically designed to apply graduated pressure to your legs. The pressure is strongest at the ankle and gradually decreases up the leg. This external support system helps to squeeze the vein walls, which in turn helps the damaged valves close more effectively and improves the overall movement of blood back to the heart.

Compression stockings come in different pressure grades, or classes, and it is vital to be fitted by a healthcare professional to ensure you are using the correct size and pressure for your condition. While wearing tight stockings in Singapore’s tropical climate can be challenging, there are ways to adapt. Lighter, more breathable materials are available, and it is most important to wear them during periods of prolonged sitting or standing, such as at a desk job or during a long flight. Putting them on first thing in the morning, before swelling begins, makes them easier to apply and more effective throughout the day.

Advanced Medical Treatments Available in Singapore

When conservative measures are not enough to manage symptoms, or if the condition progresses, a range of minimally invasive treatments are available to permanently close or remove the problematic veins. These modern procedures are performed by vascular specialists in Singapore, often require only local anaesthesia, and allow for a quick return to normal activities.

Endovenous Thermal Ablation (EVTA)

This is one of the most common and effective treatments for large varicose veins like the great saphenous vein. Using ultrasound guidance, the surgeon inserts a thin catheter into the diseased vein. In Endovenous Laser Therapy (EVLT), a laser fibre is passed through the catheter, while in Radiofrequency Ablation (RFA), a radiofrequency electrode is used. Both methods deliver controlled heat to the vein wall, causing it to collapse and seal shut. The body then naturally reroutes blood flow through other, healthy veins. The treated vein is gradually reabsorbed by the body over several months.

Sclerotherapy

Sclerotherapy is a highly effective treatment, especially for smaller varicose veins and spider veins. It involves the injection of a special chemical solution, called a sclerosant, directly into the vein. This solution irritates the lining of the vein, causing it to swell, stick together, and eventually close off. The vein turns into scar tissue and fades from view over time. Depending on the number and size of the veins being treated, multiple sessions may be required to achieve the desired result.

Non-Thermal, Non-Tumescent Options

Newer technologies have emerged that do not require heat, which eliminates the need for multiple injections of tumescent anaesthesia around the vein. VenaSeal, for instance, uses a medical-grade adhesive to glue the vein walls together. ClariVein is a mechanochemical ablation device that uses a rotating wire to disrupt the vein lining while simultaneously dispensing a sclerosant. These options offer a comfortable patient experience and a very rapid recovery.

Surgical Options

Traditional open surgery, known as high ligation and vein stripping, was once the only treatment available. It involves tying off the diseased vein and physically removing it through small incisions. While it is still a very effective procedure, it has largely been replaced by the less invasive techniques described above. Surgery is now typically reserved for very large, tortuous veins or specific cases where endovenous treatments are not suitable.

Taking Control of Your Venous Health

Managing varicose veins is a journey that involves understanding your condition, adopting proactive lifestyle habits, and exploring the effective treatments available. For mothers in Singapore, it is important to view varicose veins not as a cosmetic inconvenience but as a manageable medical condition. By listening to your body, recognising the symptoms, and seeking timely medical advice, you can effectively alleviate discomfort and prevent future complications.

You should consult a doctor if you experience persistent leg pain or swelling, significant skin changes such as discoloration or hardening, the development of a skin ulcer near your ankle, or if a varicose vein becomes tender, warm, and red, which could indicate a blood clot. Modern medicine offers a suite of safe and effective solutions. Taking the step to have your veins assessed is an investment in your long-term health, mobility, and quality of life, allowing you to stay active and engaged in all the joys of motherhood.
