Do People Die from Varicose Veins: A Doctor's Honest Answer

Varicose veins on their own do not kill. The danger arises when complications develop: thrombophlebitis, deep vein thrombosis, pulmonary embolism, or bleeding from a varicose node. With timely consultation and monitoring, these scenarios can usually be prevented.

A person notices a bulging vein, heaviness by evening, or swelling after a workday. There may be no pain. So they put off getting checked for months or years: 「If it doesn't hurt, it can't be serious.」 In practice, the absence of pain does not indicate how safe the condition of the veins actually is.

I have been working in vascular surgery since 2019. During a consultation, I first assess the complaints and perform a vein duplex ultrasound, and only then discuss whether treatment is needed and which kind.

How varicose veins can become dangerous

A varicose vein is dilated, its valves work improperly, and blood does not move as efficiently as it should. This alone does not mean a person will necessarily develop a clot or another serious complication. But stagnant blood creates conditions for problems.

The sequence patients ask about looks like this:

varicose veins → thrombophlebitis → deep vein thrombosis → pulmonary embolism.

Thrombophlebitis is more often associated with a superficial vein. It can become firm and painful, with the skin over it turning red and warm. But appearance alone cannot reliably show where the superficial process ends and whether the deep veins are involved. This requires a vein duplex ultrasound.

Deep vein thrombosis may present as one-sided swelling, pain, a feeling of fullness, or a change in skin color. Sometimes the symptoms are moderate. In some cases, a clot can travel with the bloodstream to the pulmonary arteries. This is no longer a situation for home observation.

With timely consultation, this outcome from varicose veins is rare. But 「rare」 does not mean 「impossible,」 so pronounced new symptoms should not be explained away as simple tiredness or the weather.

Why the absence of pain is not reassuring

Varicose veins develop gradually. A person gets used to their legs and notices changes only once they become pronounced. For one person, it is a web of spider veins; for another, large bulging veins, swelling, itching, or night cramps.

Signs worth paying attention to:

• one leg has become noticeably larger than the other;
• swelling appears regularly, especially by evening;
• a vein has become painful, firm, or hot to the touch;
• the skin over a vein has turned red;
• new pain in the calf appears while walking or at rest;
• the skin on the lower leg has darkened, become dense, or started flaking;
• a wound has appeared that won't heal;
• a varicose node is easily injured or occasionally bleeds.

Heaviness and swelling do not always mean varicose veins. Similar complaints can arise from other conditions of the veins, lymphatic system, joints, or internal organs. So do not diagnose yourself from photos on the internet. If leg swelling is a concern, the cause needs to be determined in person.

My simple home test does not replace a medical exam, but it helps you understand that a visit shouldn't be delayed:

• Compare both legs in the morning and in the evening.
• Check whether swelling appears on only one leg.
• Note whether there is redness, localized warmth, or a painful firm area.
• Check whether a dent remains after pressing a finger on the swollen area for a few seconds.
• Write down when the changes started and whether they worsen after long periods of standing, a flight, or exertion.

If symptoms are new, one-sided, or rapidly worsening, do not try to treat them yourself with ointments and massage. An examination and ultrasound, as indicated, are needed.

When to see a doctor urgently

Seek emergency medical care if you experience:

• sudden shortness of breath or a feeling of not getting enough air;
• pain or severe discomfort in the chest;
• coughing up blood;
• fainting, marked weakness, cold sweat;
• rapidly increasing one-sided leg swelling;
• severe pain in the calf or thigh with no clear cause;
• redness and a painful hardened area spreading up the leg;
• bleeding from a varicose vein that does not stop after proper bandaging.

Before seeing a doctor, do not massage a painful or swollen leg or try to actively work it. Do not take anticoagulants or antibiotics on your own: these medications have indications, contraindications, and a risk of complications.

What to do if a varicose node starts bleeding

A varicose vein sits close to the skin. It can be damaged by a nail, a towel, a razor, or even a minor injury. The bleeding can sometimes look more severe than expected, especially if the leg is lowered.

Steps to take:

• Lie down.
• Raise the bleeding leg above the level of your heart.
• Apply a firm pressure bandage of clean cloth or gauze over the bleeding site.
• Maintain continuous pressure, without removing the bandage every few seconds to check.
• If the bleeding continues, the bandage soaks through quickly, or weakness appears, call an ambulance.

Do not use a tourniquet. Improper application can damage tissue and worsen circulation. Do not try to puncture, cauterize, or 「seal」 the vein yourself.

Even if the bleeding has stopped, the node should be examined by a doctor. It's important to determine which vein bled, whether other veins are affected, and whether treatment is needed.

Myths, examination, and treatment

Myth: if varicose veins don't hurt, there's no need to get checked.

In reality, the intensity of pain does not always match the risk of complications. Sometimes noticeable veins cause almost no discomfort, yet ultrasound reveals impaired venous flow. The opposite can also happen: significant heaviness may be linked not to dangerous thrombosis but to another cause.

Myth: any clot from varicose veins is bound to break off.

No. Assessing a clot requires evaluating its location, extent, and the condition of the deep veins. The appearance of the leg alone cannot predict how a clot will behave. You can read more about the mechanism and symptoms in the article can a blood clot break off.

The correct sequence of steps is usually as follows:

• write down your complaints and note when they started;
• get a vein duplex ultrasound if your doctor recommends it;
• discuss the results with the doctor directly, not just get a photo of the report;
• clarify what is happening with the superficial and deep veins;
• find out whether there are signs of thrombophlebitis, thrombosis, or impaired outflow;
• get a written plan: observation, compression, medication, or a procedure;
• clarify which symptoms require immediate medical attention.

If the examination shows that varicose vein treatment is needed, the method is chosen based on vein anatomy and the clinical situation. I perform endovenous laser ablation with a Biolitec laser, sclerotherapy, CLaCS, and mini-phlebectomy.

EVLA treats the diseased vein from the inside. In current practice, the method's success rate exceeds 95%, but the specific outcome depends on vein anatomy, coexisting conditions, and adherence to recommendations. It would be wrong to promise the same result for every patient.

Sclerotherapy is used for specific vessels and veins. The medication is injected into the vein, including as foam under Echo-Foam guidance. The method is chosen not based on the patient's preference but after assessing the vascular network.

CLaCS is designed for spider veins. It combines cryo-laser with sclerotherapy: the laser acts through the skin, and the sclerosant is injected into the feeding branch of the vessel. Nothing is removed through punctures. Removing prominent superficial veins through small punctures falls under mini-phlebectomy.

It is not correct to determine the cost of treatment in advance without an ultrasound: the final estimate is drawn up in writing after the examination and discussion of the plan.

What you can do today

If you only have a longstanding web of spider veins with no new symptoms, this is not a reason to panic. But if the veins have become more noticeable, or swelling, heaviness, or night cramps have appeared, schedule an in-person consultation.

Before your visit:

• don't sit motionless for hours: get up and walk a little;
• during a long trip, regularly move your feet and ankles;
• don't injure bulging veins;
• don't apply heat to a painful area;
• don't start compression, medication, or massage without understanding the cause of the symptoms;
• bring previous reports and a list of medications you're taking to the appointment.

The practical takeaway is simple: varicose veins themselves are usually not fatal, but dangerous complications cannot be ruled out based on the absence of pain or appearance alone. New one-sided swelling, redness, a firm painful vein, shortness of breath, or bleeding require timely medical evaluation. The key step is a timely vein duplex ultrasound and a clear action plan based on its results.
