What Are Varicose Veins? Causes, Symptoms, and Treatment Options
Request Call Back
Overview
Varicose veins are enlarged, twisted surface veins—most often on the legs—that develop when the one-way valves inside the veins no longer close properly. Instead of flowing upward toward the heart, blood leaks backward (reflux), increases pressure in the vein, and stretches the vein wall. While many people seek care for cosmetic reasons, varicose veins can signal chronic venous disease (CVD) and may lead to pain, swelling, inflammation of the skin (stasis dermatitis), and—if untreated—venous leg ulcers.
At MedicalPoint Hospital, our multidisciplinary team in Vascular Surgery, Dermatology, Cardiology, and Radiology evaluates venous problems with Duplex ultrasound and provides personalized, guideline-based care.
How Common—and How Serious—Is It?
Varicose veins are common in adults and can range from small, thread-like spider veins to large rope-like superficial veins. Although many cases are mild, progressive venous reflux can impair mobility, disturb sleep due to aching and cramps, and increase the risk of complications such as superficial vein thrombophlebitis and, less commonly, deep vein thrombosis (DVT).
Types of Varicose Veins (Clinical Overview)
Doctors often classify venous disease using the CEAP system (Clinical, Etiologic, Anatomic, Pathophysiologic). For everyday understanding, you may hear:
- Spider veins (telangiectasias): Red-blue lines in the skin; cosmetic, may sting or itch.
- Reticular veins: Blue-green veins just below the skin; often network-like behind the knees or on the thighs.
- True varicose veins: Bulging, tortuous veins ≥3 mm in diameter from reflux in the great or small saphenous veins or their tributaries.
- Complicated disease: Skin changes (hyperpigmentation, lipodermatosclerosis), eczema/dermatitis, or venous ulcers around the ankle.
- Thrombotic involvement: Superficial clot (phlebitis) or coexisting DVT—requires urgent assessment.
Note: Terms like “dermatitis varix” reflect skin inflammation from long-standing venous hypertension rather than a separate vein “type.”
Why Do Varicose Veins Form? (Causes and Risk Factors)
Varicose veins reflect a combination of venous valve failure and vein wall weakness. Contributors include:
- Genetics/family history – the strongest predictor.
- Age – connective tissue and valves degenerate over time.
- Female sex & hormones – pregnancy, estrogen/progestin exposure; pregnancy also raises blood volume and abdominal pressure.
- Obesity/central weight gain – increases venous pressure and reduces calf-muscle pump efficiency.
- Occupational standing or prolonged sitting – hairdressers, teachers, retail, factory and office work.
- Previous DVT or leg injury – can damage valves (post-thrombotic syndrome).
- Low physical activity & smoking – impair vascular health and microcirculation.
- Constipation or chronic cough – raise intra-abdominal pressure and venous strain.
Symptoms to Watch For
- Aching, heaviness, throbbing, or burning in the legs, worse late in the day
- Swelling around the ankles (edema)
- Night cramps or restless legs
- Itching or eczema over the veins; brown/purplish skin discoloration near the ankles
- Visible bulging veins or clusters of spider/reticular veins
- In advanced cases: hard, tight skin (lipodermatosclerosis) or a non-healing ulcer above the medial ankle
Seek urgent care if you develop sudden one-sided leg swelling, warmth, redness, or severe pain—possible DVT.
Who Is Most at Risk?
- People with a first-degree relative with varicose veins
- Women, especially during or after pregnancy
- Adults >40–50 years
- Individuals with BMI in the overweight/obese range
- Workers with prolonged standing or sitting without breaks
- Those with prior leg trauma, DVT, or pelvic masses
- People with limited mobility or chronic cough/constipation
Can Varicose Veins Be Prevented?
Not entirely—genetics and age matter—but you can reduce symptoms and slow progression:
- Move regularly: Calf-muscle contractions are the “second heart.” Walk hourly; perform heel-raises and ankle pumps.
- Weight management & activity: Aim for 150 minutes/week of moderate exercise; cycling and swimming are excellent.
- Elevate legs: 10–15 minutes, 1–3 times/day, ankles above heart level.
- Avoid long static postures: Alternate sitting/standing; use a footstool; change leg position often.
- Compression therapy: Graduated compression stockings (often 15–20 mmHg or 20–30 mmHg as advised) reduce swelling and discomfort.
- Skin care: Gentle cleansers, daily emollients; treat eczema early to prevent ulcers.
- Stop smoking and moderate alcohol.
- During pregnancy: Side-sleeping (left), walking, and maternity compression after obstetric advice.
How Are Varicose Veins Diagnosed?
A vascular specialist will:
- Take a focused history and examine the legs (standing) for vein patterns, skin changes, and edema.
- Order Duplex ultrasound to map reflux, confirm which veins are incompetent (e.g., great/small saphenous, perforators), and exclude DVT.
- Use CEAP staging to guide treatment and monitor response.
Ultrasound mapping is essential before any procedure; it ensures the right vein is treated at the right segment.
Treatment Options at MedicalPoint Hospital
1) Conservative (Non-procedural) Care
- Graduated compression stockings: Reduce edema and pain; often first-line and also used after procedures.
- Exercise & physiotherapy: Calf strengthening, walking programs.
- Lifestyle measures: Leg elevation, ergonomics at work, weight reduction.
- Medications (venoactive agents): Micronized purified flavonoid fraction, horse chestnut seed extract, or rutosides may relieve heaviness or cramps in some patients. Evidence quality varies—discuss suitability with your clinician, especially if you take anticoagulants or are pregnant.
Conservative therapy alleviates symptoms but does not “repair” failed valves.
2) Minimally Invasive Endovenous Therapies
Guidelines (e.g., Society for Vascular Surgery, American Venous Forum, NICE) favor endovenous techniques over surgical stripping for most refluxing saphenous veins:
- Endovenous Thermal Ablation
- Radiofrequency ablation (RFA) or Endovenous laser ablation (EVLA) heat and seal the faulty vein via a catheter under local anesthesia.
- Benefits: Day-procedure, small punctures, rapid return to activity, high closure rates.
- Ultrasound-Guided Foam Sclerotherapy
- A foamed sclerosant is injected to collapse targeted segments or tributaries. Useful for tortuous veins and recurrences; may need staged sessions.
- Cyanoacrylate Closure (medical adhesive)
- Closes the saphenous vein without tumescent anesthesia or heat; compression may be optional in some protocols.
- Ambulatory Phlebectomy (micro-phlebectomy)
- Micro-extraction of bulging tributaries through tiny punctures; often combined with ablation.
Aftercare: Short walks the same day, compression as advised, and follow-up ultrasound to confirm closure and exclude rare complications (endovenous heat-induced thrombosis).
3) Surgical Options (Selected Cases)
- High ligation and stripping or phlebectomy-only procedures are reserved for anatomy not suitable for endovenous techniques or where prior treatments have failed. These are performed under regional or general anesthesia and now less common than minimally invasive options.
Special Situations
- Pregnancy: Focus on symptom control (compression, activity, elevation). Definitive procedures are typically deferred until after delivery and lactation unless complications occur.
- Venous Ulcer: Requires multilayer compression, wound care, and addressing underlying reflux (often with endovenous ablation) to improve healing and reduce recurrence.
- Superficial Thrombophlebitis: Painful, red cord-like vein; ultrasound evaluation is important to check for extension toward deep veins. Management may include NSAIDs, compression, mobilization, and in select cases anticoagulation.

Frequently Asked Questions
Do varicose veins come back after treatment?
New veins can develop over time if the underlying tendency persists, but treating the refluxing “source” veins significantly reduces symptoms and recurrence. Periodic ultrasound surveillance helps.
Are compression stockings mandatory?
They ease symptoms and are commonly advised after procedures; strength and duration depend on the technique used and your clinician’s plan.
Is treatment purely cosmetic?
No. Treating documented reflux in symptomatic patients improves pain, swelling, skin health, mobility, and ulcer healing, in addition to cosmetic benefits.
Evidence and Standards We Follow
Care aligns with major clinical guidance (e.g., Society for Vascular Surgery/American Venous Forum, NICE CG on varicose veins, European Venous Forum consensus) and is tailored to individual anatomy and goals. Your clinician will discuss benefits, risks (e.g., bruising, pigmentation, nerve irritation, rare thrombosis), and realistic expectations.
