Chronic leg discomfort, swelling, and visible varicose veins can often be linked to a condition known as venous reflux—also called chronic venous insufficiency. It’s more common than many realize and, when left untreated, can lead to skin changes, leg ulcers, and significant lifestyle limitations.
In this article, we’ll explain what venous reflux is, what causes it, its symptoms, and the most effective treatments currently available in Singapore. Whether you’re just beginning to notice symptoms or you’ve been managing vein issues for a while, this guide will help you understand your options.
💡 What Is Venous Reflux?
Venous reflux occurs when the valves in your leg veins stop working properly. These valves are supposed to keep blood flowing upward toward the heart. When they weaken or become damaged, blood flows backward (refluxes) and pools in the lower legs.
Over time, this backward flow increases pressure in the veins, leading to:
- Swollen, twisted veins (varicose veins)
- Heaviness and aching
- Skin discoloration and ulcers in severe cases
This condition is progressive, so early diagnosis and treatment are important.
🔍 Common Symptoms of Venous Reflux
Venous reflux symptoms may vary in intensity, but common signs include:
- Aching, cramping, or heaviness in the legs
- Swelling around the ankles, especially after long periods of standing
- Visible varicose veins
- Itchy, dry, or flaky skin on the legs
- Darkened skin or pigmentation changes
- Open sores or leg ulcers, usually around the ankles
- Nighttime leg cramps
Symptoms often worsen after standing or sitting for long hours and improve when you elevate your legs.
⚠️ What Causes Venous Reflux?
Several risk factors can increase your likelihood of developing venous reflux:
| Risk Factor | Explanation |
| Age | Valve function weakens with age |
| Family History | Genetics can predispose you to valve dysfunction |
| Pregnancy | Increases pressure on pelvic and leg veins |
| Prolonged Standing/Sitting | Slows venous return |
| Obesity | Adds pressure on veins |
| Previous DVT (clots) | Can damage valves |
| Lack of Exercise | Reduces blood flow and circulation |
🧪 How Is Venous Reflux Diagnosed in Singapore?
Diagnosis begins with a consultation with a vascular doctor in Singapore, followed by:
- Physical Examination—Your doctor will check for visible vein issues and skin changes.
- Duplex Ultrasound—This noninvasive test visualizes blood flow and evaluates whether valves are functioning properly.
Early diagnosis ensures appropriate treatment and helps prevent long-term complications.
🏥 Latest Treatment Options for Venous Reflux in Singapore
Thankfully, modern vein care in Singapore has advanced significantly, offering minimally invasive and effective treatments:
🔹 1. Radiofrequency Ablation (RFA)
- A catheter delivers controlled heat to close off damaged veins.
- Performed under local anesthesia.
- Outpatient procedure with fast recovery.
🔹 2. Endovenous Laser Treatment (EVLT)
- Laser energy seals the affected vein.
- Precise, quick, and minimally invasive.
🔹 3. VenaSeal™ Closure System
- Uses medical adhesive to seal the vein.
- No need for compression stockings post-procedure.
- Minimal discomfort and downtime.
🔹 4. ClariVein® Mechanochemical Ablation
- Combines mechanical and chemical treatment to close veins.
- No heat or tumescent anesthesia required.
🔹 5. Surgical Options
- Reserved for complex cases.
- Includes vein stripping or phlebectomy.
All of these are available at leading vascular clinics in Singapore, including those covered by NTUC IncomeShield and other Integrated Shield Plans.
🩺 What Happens After Treatment?
Most patients return to normal activity within 24–48 hours. Depending on the procedure, your doctor may recommend:
- Wearing compression stockings
- Avoiding prolonged standing
- Light walking to encourage blood flow
- Follow-up ultrasound scans to confirm vein closure
Long-term outcomes are excellent when treated early, and recurrence is significantly reduced with modern techniques.
