Varicose Veins and Menopause: What Is the Connection and When to Seek Advice

Many women begin to pay closer attention to their legs when they reach menopause. Veins that were not visible before may appear, leg heaviness may increase by the end of the day, or the ankles may swell. It is natural to wonder whether hormonal changes are responsible.

The short answer is that menopause may coincide with the time when varicose veins become visible or cause more discomfort, but the fall in oestrogen levels has not been shown to be the cause on its own. Venous disease is multifactorial: age, heredity, previous pregnancies, weight, mobility and many years of standing or sitting at work all play a part.

We will distinguish what is known from what remains a hypothesis, and explain which measures are reasonable and when it may be appropriate to assess your circulation.

Does menopause cause varicose veins?

Varicose veins develop when certain superficial veins become enlarged and their valves no longer close properly. Gravity then causes blood to flow back downwards, increasing the pressure inside the vein. This process usually develops over many years.

Some older studies found that many women recalled their varicose veins beginning around menopause. In one study, 38.2% of women with varicose veins identified this stage as the time of onset. This is an interesting finding, but it was based on older patients’ recollections and cannot distinguish the effect of hormones from the effects of age, weight, pregnancies or daily activity.

A more accurate way to put it is this: menopause is a point in time, not a proven cause of venous disease. It may be the stage when several accumulated factors cross the threshold at which veins become visible or symptomatic.

Hormones and the vein wall: what we actually know

Veins have receptors for oestrogen and progesterone, so sex hormones do influence their tone, distensibility and remodelling. What science has not established is whether this influence initiates varicose veins, promotes them only in some women, or changes as a consequence of the disease itself.

In fact, the human study most directly related to this question found that, among menopausal women who were not receiving hormone therapy, higher oestradiol levels were associated with greater venous distensibility and more varicose veins. It was a small cross-sectional study and therefore does not prove causation, but it does challenge the simplistic explanation that “less oestrogen makes veins weak”.

A more distensible vein is not necessarily a vein that works better. If its diameter increases too much, the valve leaflets may no longer meet in the centre and reflux can develop. Venous biology is considerably more complex than a simple loss of elasticity.

The factors that matter most at this stage

Around menopause, biological and lifestyle changes coincide and may increase the strain on the venous system. The most relevant factors include:

• Family predisposition. Having relatives with varicose veins increases the likelihood of developing them.
• Previous pregnancies. A meta-analysis of nine studies involving more than 17,000 women found an association between a history of pregnancy and varicose veins. Pregnancy combines hormonal changes, increased blood volume and mechanical pressure in the pelvis.
• Excess weight. In a small study of postmenopausal women, obesity was associated with varicose veins even after adjusting for sex hormones. Excess weight may increase abdominal pressure and make it harder to stay mobile.
• Spending many hours without moving. Prolonged periods of standing or sitting reduce the action of the calf muscle pump.
• Age and previous venous disease. Remodelling of the vein wall and valves accumulates over decades; veins that were already predisposed may begin to cause symptoms at this stage.

These factors do not affect everyone in the same way. Two women of the same age and with the same hormonal status may have completely different venous health.

Heaviness, cramps and swelling: it is not always varicose veins

Heaviness, pain, cramps or ankle swelling may accompany venous insufficiency, but they are not specific to it. At this stage, joint problems, lymphoedema, lipoedema, neuropathies, the effects of some medicines, or heart and kidney disease may also be present.

This is why “heavy legs” should not automatically be attributed to menopause. The distribution and duration of the swelling, whether it affects one or both legs, and any skin changes all help guide the diagnosis. Our article on why legs swell explains the most common differences.

Sudden swelling in one leg, especially when accompanied by pain, warmth or redness, requires urgent medical assessment to rule out thrombosis. It should not be confused with the usual worsening of varicose veins.

What you can do to look after your circulation

No measure can guarantee that varicose veins will never develop, and general advice will not remove veins that are already established. These measures may, however, help reduce discomfort, improve muscle function and avoid unnecessary strain:

• Walk regularly and stay physically active in a way that is appropriate for your health.
• If you work sitting or standing, change position and move your ankles frequently.
• Avoid long periods of immobility; on long journeys, stand up or flex your ankles whenever possible.
• Aim to maintain a healthy weight without relying on “detox” claims or products that promise to cleanse your veins.
• Raise your legs for a few minutes if they feel heavy at the end of the day.
• Seek advice before buying compression stockings: the type, size and level of compression should be selected for your individual needs.

These measures are part of sensible vascular care, but they should not be presented as a way to “compensate” for lower oestrogen levels.

Hormone therapy, varicose veins and thrombosis risk

Menopausal hormone therapy should not be used to prevent or treat varicose veins. There is also no strong evidence that uncomplicated varicose veins are, on their own, an absolute contraindication to receiving it.

It is essential to distinguish between two different problems. Varicose veins are part of superficial venous disease; venous thromboembolism includes deep vein thrombosis and pulmonary embolism. The evidence regarding hormone therapy is much stronger for this second risk: oral oestrogens increase the risk of venous thromboembolism, whereas transdermal preparations appear to have a smaller effect.

The indication, preparation and route of administration should be decided on an individual basis with the healthcare professional managing menopause, taking into account personal or family history of thrombosis, obesity, immobility, thrombophilia and other factors.

When to seek advice and what venous Duplex Ultrasound shows

There is no need for every woman to have a venous ultrasound simply because she has reached menopause. It is advisable to seek assessment when visible varicose veins cause symptoms, swelling persists, the skin changes colour or becomes hardened, phlebitis or bleeding occurs, a wound does not heal, or there are questions before starting treatment.

The clinical examination helps determine whether the symptoms are consistent with venous disease. When indicated, a venous Duplex Ultrasound shows how blood flows through the veins, identifies reflux and helps distinguish isolated visible veins from venous insufficiency that requires specific treatment planning.

Treatment is not chosen on the basis of age or menopause, but according to the anatomy, symptoms, Duplex Ultrasound findings and the patient’s preferences. Conservative measures may be sufficient in some cases; in others, sclerotherapy, phlebectomy or endovenous techniques may be considered. The important point is to choose carefully rather than treating every pair of legs in the same way.

FREQUENTLY ASKED QUESTIONS

Does menopause cause varicose veins?

Menopause has not been shown to be an independent cause of varicose veins. It occurs at an age when accumulated factors such as family predisposition, pregnancies, excess weight or many years of standing or sitting at work may become apparent.

Does the fall in oestrogen weaken the veins?

That explanation is too simplistic. Sex hormones do influence the vein wall, but the most directly relevant human study found greater distensibility and more varicose veins with higher oestradiol levels. The direction of this effect is still not fully understood.

Does hormone therapy make varicose veins worse?

Evidence specifically addressing the onset or progression of varicose veins is weak and inconsistent. Hormone therapy is not prescribed to treat varicose veins; the decision should focus mainly on the overall risk of venous thromboembolism and the route of administration.

Do I need a venous Duplex Ultrasound when I reach menopause?

Not for menopause alone. It may be indicated if varicose veins are symptomatic, swelling persists, there are skin changes, phlebitis or recurrence, or treatment is being planned.

Can walking get rid of varicose veins?

Walking activates the calf muscle pump and may relieve heaviness or swelling, but it does not make an established varicose vein disappear. If symptoms persist, their cause should be assessed.
