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
- Family history — strong genetic component
- Increasing age
- Pregnancy (increased blood volume and hormonal changes)
- Prolonged standing occupations
- Obesity
- Previous deep vein thrombosis
When to Seek Treatment
| Symptom | Concern Level |
|---|---|
| Cosmetic appearance only | Not medically necessary but treatment available if desired |
| Aching, heaviness, throbbing | Consider 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, redness | Urgent assessment — rule out DVT or infection |
Treatment Options
| Treatment | Description |
|---|---|
| Compression stockings | First-line — reduces symptoms, doesn't reverse veins |
| Endovenous laser/radiofrequency ablation | Minimally invasive — closes the faulty vein from inside |
| Sclerotherapy | Injection that closes smaller veins — good for cosmetic treatment |
| Vein stripping surgery | Traditional 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.
