Up to 30% of adults have varicose veins, with higher rates in those whose occupations require prolonged standing or sitting.
Nurses, teachers, retail workers, hairdressers, restaurant staff, factory workers, surgeons, and many other professionals spend much of their working day on their feet. While standing may seem healthier than sitting at a desk all day, remaining upright for long periods brings its own challenges.
At Vascular Surgery Associates, LLC, we know that spending many hours standing at work increases the risk of varicose veins and other chronic venous diseases. Understanding why can help you recognize early symptoms and take practical steps to protect your circulation.
Your leg veins have a demanding job returning blood upward toward your heart while working against gravity. Small valves inside healthy veins help prevent blood from flowing backward. Your calf muscles also act as a pump that keeps the flow moving.
Every time you walk or flex these muscles, they squeeze nearby veins and help push blood toward your heart. The system works particularly well when you move, while standing still creates a different situation.
When you remain upright without much movement, blood can collect in the veins of your lower legs, which increases pressure inside the veins. Over time, persistently high venous pressure can create strain on vein walls and valves.
If the valves stop closing effectively, some blood can flow backward and pool in the vein. The vein may then enlarge and become twisted, creating the raised blue or purple blemishes we recognize as varicose veins.
There isn't a precise number of hours after which you develop varicose veins because your individual risk depends on several factors. However, research examining occupational venous disease has found an association between standing for more than three to four hours a day and an increased risk of varicose veins.
The way you stand matters too. Walking activates your calf-muscle pump, while standing relatively still at a checkout, operating table, production line, salon chair, or classroom gives your leg muscles less opportunity to assist blood flow.
The effect can also accumulate over a working life. Someone who regularly spends long shifts standing may experience repeated periods of raised pressure in the leg veins.
Long hours on your feet don't automatically mean you develop varicose veins. Some people spend their entire careers standing and never experience significant vein problems. Other factors that increase your susceptibility include:
Several risk factors often work together. For example, someone with a significant family history of varicose veins may notice symptoms earlier if their job also requires eight-hour shifts on their feet.
Varicose veins don't always start with obvious bulging vessels. Chronic venous disease can produce symptoms before prominent veins develop.
You may notice:
These problems are usually particularly noticeable toward the end of a long shift. Symptoms may improve when walking, resting, or elevating your legs.
As venous disease progresses, skin around the lower leg or ankle can also become dry, itchy, discolored, or thickened. More advanced disease can cause slow-healing sores called venous ulcers.
We can evaluate your symptoms and determine whether chronic venous disease is affecting circulation in your legs. An ultrasound allows us to assess blood flow and identify veins with poorly functioning valves. Advanced treatments that address abnormal veins without traditional major vein surgery include:
You can't necessarily avoid standing if it's essential to your job, but small changes can reduce long periods of static standing.
Walk briefly whenever your work allows. Shift your weight between your feet, perform gentle heel raises, or flex your ankles if you need to remain in one place. These movements activate your calf muscles and encourage blood to travel upward.
When possible, alternate between sitting, standing, and walking instead of staying in one position for hours. And when you get home, elevate your legs to help reduce swelling after a long shift.
Don't assume prominent veins are simply an unavoidable consequence of your occupation. If long working days leave your legs aching, swollen, heavy, or increasingly covered with varicose veins, contact Vascular Surgery Associates, LLC, by phone or online today to schedule a vascular evaluation.
