Varicose Veins: Causes & Treatment

Varicose veins affect up to 30% of adults. While often just a cosmetic concern, they can occasionally cause complications requiring treatment.

Prevalence
Up to 30% of adults
More common in
Women, with age, pregnancy
Cause
Faulty vein valves
Complication
Venous ulcers (in severe cases)

Why Varicose Veins Develop

Veins contain one-way valves that keep blood flowing towards the heart against gravity. When these valves weaken or fail, blood pools in the veins, causing them to become enlarged, twisted, and visible under the skin — typically in the legs.

Risk Factors

When to Seek Treatment

SymptomConcern Level
Cosmetic appearance onlyNot medically necessary but treatment available if desired
Aching, heaviness, throbbingConsider treatment for symptom relief
Skin changes (brown discolouration, hardening)See a doctor — sign of chronic venous insufficiency
Venous ulcer (open sore, usually near ankle)Requires medical treatment — doesn't heal without addressing the underlying vein problem
Sudden severe pain, swelling, rednessUrgent assessment — rule out DVT or infection

Treatment Options

TreatmentDescription
Compression stockingsFirst-line — reduces symptoms, doesn't reverse veins
Endovenous laser/radiofrequency ablationMinimally invasive — closes the faulty vein from inside
SclerotherapyInjection that closes smaller veins — good for cosmetic treatment
Vein stripping surgeryTraditional surgical removal — less common now with newer techniques
Self-Help MeasuresRegular walking, elevating legs when resting, avoiding prolonged standing/sitting, maintaining healthy weight, and wearing compression stockings can all reduce symptoms and slow progression of varicose veins.
Are varicose veins dangerous?
Usually not — most varicose veins are a cosmetic and mild comfort issue rather than a dangerous condition. However, complications like venous ulcers or, rarely, bleeding from a vein can occur and need treatment.
Will varicose veins come back after treatment?
New varicose veins can develop over time even after successful treatment of existing ones, as the underlying tendency to weak vein valves remains, particularly if there's a strong family history.
Are varicose veins the same as spider veins?
No — spider veins (telangiectasia) are smaller, red or blue veins visible near the skin surface, while varicose veins are larger, raised, and often twisted or bulging veins.
