Risk factors for varicose veins: a comprehensive overview

Curious about the risk factors for varicose veins? Perhaps someone in your family already suffers from the condition, or you simply want to rule out the possibility of developing varicose veins yourself. If so, this article is for you. We’ll explain what varicose veins are, how they occur, what risk factors are involved, and what treatment options are available.

Today’s article also features a video by Dr. Omar, where you can hear directly from a varicose vein expert about the risk factors for developing varicose veins.

What are varicose veins?

Varicose veins are enlarged, dilated, and misshapen veins that typically occur in the legs. Mechanically, they develop when venous valves, designed to allow blood to flow in only one direction (toward the heart), stop functioning properly. As a result, blood pools in the veins, increasing pressure and causing them to dilate.

On the outside, varicose veins are easy to recognize: they appear as bluish or purple cords bulging beneath the skin. Common symptoms include a feeling of heaviness in the legs, pain, itching, swelling, or even cramps, especially after prolonged standing or at the end of the day.

Genetics as a risk factor for varicose veins

One of the most important risk factors is genetic inheritance. Varicose veins are a hereditary condition. This means that if you have first-degree relatives (parents, grandparents, brothers, sisters, aunts) who have or have had varicose veins, your own risk of developing them is significantly higher.

Why does this happen? Because the tendency for vein walls and valves to weaken can be passed down genetically. In other words, you inherit the “terrain” that makes the condition more likely to develop.

Are spider veins an early indicator of varicose veins?

Yes, they can be. Even if you don’t have relatives with varicose veins, the presence of so-called spider veins or thread veins may indicate a genetic predisposition to developing varicose veins.

What are spider veins?

Spider veins are small, dilated blood vessels that appear under the skin, especially on the thighs or face. These veins are red, blue, or purple and measure between 1 and 2 mm in diameter. They are painless and, unlike varicose veins, do not lead to medical complications. They are, however, an aesthetic problem, sometimes annoying for those who have them.

Whether or not you have a genetic predisposition and whether or not you have spider veins, it’s important to have an active lifestyle. Exercise regularly, hydrate well, avoid sitting or standing for long periods, and adopt a balanced diet.

The importance of identifying the risk factors for varicose veins

Knowing early if you are at increased risk of varicose veins can help you in several ways:

  • Active prevention: if you know you’re genetically predisposed, you can adopt a lifestyle that protects the health of your veins.
  • Early diagnosis: you’ll be more alert to the first signs—tired legs, aches, pain, swelling—and can consult your doctor earlier, before the condition worsens.
  • Effective monitoring: you’ll be more attentive to your vein health, regularly checking that everything is fine, and taking measures such as wearing compression stockings or elevating your feet when needed.

Ask your family members if anyone has or has had varicose veins; it can make a big difference in the long term.

Treatment approaches: varicose veins vs spider veins

The most commonly used treatment for spider veins is microsclerotherapy. This involves injecting a special solution directly into the affected veins, causing them to close. After that, the body gradually absorbs them. The procedure is simple, requires no general anesthesia, and is performed quickly in the doctor’s office. It is both safe and effective.

For varicose veins, treatments are more complex because they involve larger veins, often accompanied by painful symptoms. Here are some of the most modern methods:

Endovenous Laser Ablation of the veins (EVLA)

It is a minimally invasive procedure that involves inserting a catheter into the affected vein under ultrasound guidance. A laser fiber is then inserted through the catheter, which heats and destroys the vein wall. The vein “closes,” and the body gradually reabsorbs it over time. The procedure is performed under local anesthesia and takes about 30 minutes.

Endovenous Microwave Ablation of the veins (EMWA)

Similar to EVLA, but instead of a laser, microwaves are used to destroy the affected vein. The procedure is painless and does not require direct contact with the vein wall. It is performed under local anesthesia, and recovery is rapid.

SONOVEIN (High-Intensity Focused Ultrasound Ablation – HIFU)

This is the most modern, completely non-invasive method. It involves no incisions, needles, or catheters. Using high-intensity ultrasound, heat is generated at a precise point in the vein wall, causing it to collapse. The procedure is very well tolerated and is suitable for patients who want to avoid traditional interventions.


FAQ about risk factors for varicose veins

  1. If my mom has varicose veins, is it certain that I will have them too?
    It’s not certain, but you do have a higher risk compared to someone with no family history.
  2. Do varicose veins only occur in older people?
    No, they don’t. Although varicose veins are more common with age, they can also occur in younger people, especially if other risk factors are present.
  3. If I already have spider veins, should I be worried about developing varicose veins?
    Not necessarily. Spider veins don’t cause pain or complications, but they may indicate a predisposition. It’s a good idea to monitor them and take care of your circulation.
  4. Can varicose veins lead to complications?
    Ignoring varicose veins might have a severe impact on the quality of life for the patients and their families. In some situations, when the condition is complicated with venous ulcers, pain can be severe, with reduced ability to walk and work, and an unpleasant odour. This can impact both the sufferer and their families’ lives. Also, if clots form in the veins (Thrombophlebitis), the risk of strokes and Pulmonary Embolisms (clots in the lungs) is very high and can be fatal.
  5. How long does it take to recover from varicose vein surgery?
    Recovery time after varicose vein treatment is practically nonexistent. Doctors encourage patients to start walking right after the procedure, even in more complex cases. Discover more about recovery times in our full article here.

Conclusion

Varicose veins have a risk factor beyond your control—a genetic predisposition. That’s why it’s important not to worry or put pressure on yourself. Identify your risks early, adopt a healthy lifestyle, and, if necessary, consult a phlebology specialist to explore the best treatment options.
