When Are You at Greatest Risk of Varicose Veins?

Varicose vein risk is not constant throughout life. It shifts significantly depending on your age, hormonal state, occupation, and other circumstances. Understanding who is at risk of varicose veins, and during which windows that risk peaks, can help you know when to be more proactive about prevention and monitoring.

During Pregnancy

Pregnancy is one of the highest-risk periods for varicose veins. Increased blood volume, hormonal changes that relax vein walls, and pressure from the growing uterus on pelvic and leg veins combine to raise risk substantially, particularly in the second and third trimesters. Risk tends to increase with each subsequent pregnancy, and veins that appear during one pregnancy may become more pronounced during the next.

Middle Age and Beyond

As you move through your 40s, 50s, and beyond, vein valves gradually lose some elasticity and efficiency, and years of cumulative pressure on the veins can catch up. This is why varicose veins become noticeably more common with age, even in people who did not have them earlier in life. Circulation naturally becomes less efficient over time, and skin and vessel walls lose some of the elasticity that helped keep earlier symptoms in check.

During Menopause

Hormonal shifts during perimenopause and menopause can affect vein wall elasticity, and some people notice new or worsening varicose veins during this transition. Declining estrogen levels are thought to play a role in how vein walls hold their structure, though the exact mechanisms are still an active area of research.

If You Have a Job That Requires Prolonged Standing or Sitting

Occupations like nursing, teaching, retail, hairdressing, food service, and office work that involve standing or sitting for most of the day are associated with elevated risk, since the calf muscle pump works less effectively when you are not moving. Workers in these fields often report symptoms worsening across a shift and easing overnight, which is a useful sign that occupational positioning is a contributing factor.

During Periods of Weight Gain

Any period of significant weight gain, whether from pregnancy, lifestyle changes, medication side effects, or other factors, increases pressure on leg veins and can raise short-term risk. This risk window tends to ease somewhat if a healthy weight is regained, though any veins that have already developed will not necessarily disappear.

After Prior Blood Clots or Vein Injuries

If you have previously experienced a deep vein thrombosis or other vein damage, your risk of developing varicose veins in the affected area is higher going forward, since damaged valves are less able to function properly even after the initial injury has healed.

During Long-Distance Travel

Extended periods of immobility, such as long flights or road trips, temporarily raise the risk of blood pooling in the legs. This is a shorter-term risk window compared to the others listed here, but it is worth taking seriously, especially if other risk factors are already present, since several risk factors can compound during travel.

If You Have a Family History

This is less a specific window and more a constant background risk worth naming on its own: if varicose veins run in your family, your risk is elevated throughout your life, and the other risk windows above will likely affect you more significantly than someone without that family history.

What to Do During High-Risk Windows

If you recognize yourself in one or more of these categories, it is a reasonable time to be more consistent about prevention habits: staying active, wearing graduated compression stockings, avoiding prolonged static positions, and paying attention to any new leg symptoms so you can address them early.

Graduated Compression Stockings

During higher-risk windows like pregnancy, long travel, or standing-heavy workdays, graduated compression stockings are a simple way to support circulation when your risk is elevated.

The Bottom Line

Risk is not static. It rises and falls with life circumstances, sometimes stacking multiple factors at once, such as a standing job during pregnancy. Recognizing which windows apply to you now, and staying attentive during them, is a more useful approach than assuming your risk is the same at every stage of life, and it puts you in a better position to catch changes early.
