Varicose Veins: Causes, Symptoms & Treatment

Medically reviewed guide by Dr. S. Kalavathi, General, Laparoscopic Surgeon & Proctologist, Narayana General & Surgical Hospital, Mancherial · Updated September 2026

That heavy, tired feeling in your legs by the end of the day, or the bulging blue-purple veins that seem to get more noticeable every year, is easy to brush off as just a normal part of getting older or being on your feet all day. But varicose veins are a real medical condition with an underlying cause — and one that's very treatable.

This guide covers what causes varicose veins, how they progress if left unaddressed, and the range of treatment options available today, from simple lifestyle changes to minimally invasive laser procedures.

What Causes Varicose Veins?

Veins carry blood back to the heart using one-way valves that stop it from flowing backward. When these valves weaken or become damaged, blood pools in the vein instead of moving forward, gradually stretching and enlarging it. Several factors make this more likely:

• Prolonged standing or sitting: Reduces how efficiently blood is pumped back up from the legs.
• Obesity: Adds extra pressure on leg veins.
• Pregnancy: Increased blood volume and hormonal changes raise the risk, especially with multiple pregnancies.
• Age: Vein walls and valves naturally lose elasticity over time.
• Family history: A genetic tendency toward weaker vein valves is common.
• Sex: Varicose veins are notably more common in women, partly due to hormonal influences.

How Varicose Veins Progress: Quick Comparison

Vein specialists often describe venous disease along a spectrum, from barely visible thread veins to advanced skin changes. Not everyone progresses through every stage, but understanding where symptoms sit helps guide treatment.

Symptoms to Watch For

• Visible bulging, twisted, or rope-like veins, usually on the legs
• A heavy, achy, or tired feeling in the legs, especially by evening
• Swelling around the ankles or lower legs
• Itching or a burning sensation over the affected veins
• Night cramps or restlessness in the legs
• Skin discoloration or thickening near the ankles, in longstanding cases

Treatment Options

• Compression stockings: Support blood flow back up the leg and ease aching and swelling; often the first step for mild cases.
• Lifestyle measures: Regular walking, leg elevation, and weight management all reduce pressure on leg veins.
• Sclerotherapy: A solution is injected into the vein, causing it to collapse and gradually fade — well suited to smaller varicose and spider veins.
• Endovenous laser ablation (EVLA): A thin catheter delivers laser energy inside the faulty vein, sealing it shut from within through a single small access point.
• Ambulatory phlebectomy: Small punctures are used to remove sections of a bulging vein close to the skin surface.
• Traditional surgery (ligation and stripping): Still used in select cases, though endovenous techniques are now generally preferred for faster recovery and less post-procedure pain.

Whichever method is used, it's worth knowing that varicose veins can occasionally recur over time, as other veins can develop the same valve problem later. Following your doctor's advice on compression and activity after treatment helps keep this risk as low as possible.

Why Endovenous Laser Treatment Is Often Preferred

• No large incisions — performed through a single small access point
• Local anaesthesia is often sufficient, avoiding general anaesthesia risks
• Less post-procedure pain compared with traditional vein stripping
• Day-care procedure for most patients, with same-day discharge
• Faster return to normal activity, often within a day or two

Common Misconceptions

• "It's only a cosmetic problem" — many people with varicose veins have genuine aching, swelling, and heaviness, not just visible veins.
• "Only older people get varicose veins" — they can appear at any adult age, particularly during or after pregnancy.
• "Treatment always means major surgery" — most cases today are managed with minimally invasive procedures done as day-care treatment.
• "Exercise makes varicose veins worse" — the opposite is usually true; walking and leg movement actually help blood flow.
• "Once treated, they never come back" — recurrence is possible with any method, which is why follow-up and lifestyle habits still matter.
