Why Do You Get Varicose Veins at a Young Age?

Varicose veins are often associated with later life, yet venous disease can develop much earlier than many people realise. It is not uncommon for patients in their twenties and thirties to experience aching legs, visible bulging veins or other symptoms caused by underlying venous reflux. In some cases, the first signs may even appear during the late teenage years.

Age remains an established risk factor for chronic venous disease, but it is only one part of a much wider picture. Genetics, occupation, pregnancy, hormonal changes, body weight, and prolonged sitting or standing can all contribute to the development of varicose veins at a relatively young age.

Early diagnosis is beneficial because modern minimally invasive treatments can address the underlying cause before venous disease progresses and complications develop.

Why Varicose Veins Develop

Healthy leg veins return blood from the feet and lower limbs back towards the heart. Because this movement occurs against gravity, veins rely on a series of one-way valves that prevent blood from flowing backwards.

When these valves become damaged or weakened, blood falls back into the vein instead of continuing upwards. This process, known as venous reflux, increases pressure within the vein and gradually stretches the vein wall.

As the pressure continues to rise, the vein enlarges, becomes tortuous and increasingly visible beneath the skin. This process is known as chronic venous insufficiency and represents the underlying cause of most varicose veins.

Varicose veins are therefore not simply enlarged veins. They are veins with abnormal valve function and altered blood flow.

Varicose Veins Are More Common Than Many Realise

Varicose veins affect a substantial proportion of the adult population within the United Kingdom.

The Edinburgh Vein Study, one of the largest UK investigations into venous disease, found trunk varicose veins in approximately 40% of men and 32% of women, with the prevalence increasing steadily with age. The study also demonstrated that venous disease is not confined to older adults, with younger age groups frequently showing early signs of venous reflux before significant visible veins develop.

NICE also recognises that symptomatic varicose veins can occur at any stage of adult life and recommends assessment when symptoms such as aching, swelling, skin changes or bleeding develop.

Genetics Often Determine When Vein Problems Begin

Inherited factors are among the strongest predictors of developing varicose veins at a younger age.

Rather than inheriting varicose veins themselves, individuals inherit characteristics that affect the strength of the vein wall and the efficiency of the venous valves.

These inherited factors may include:

Reduced strength within the vein wall
Connective tissue differences affecting vein elasticity
Valve abnormalities
A greater tendency towards venous reflux

Patients with one affected parent have a significantly increased likelihood of developing varicose veins during their lifetime. Where both parents have chronic venous disease, symptoms frequently appear much earlier.

This explains why physically active individuals with a healthy body weight may still develop varicose veins during early adulthood.

Occupation Can Accelerate Venous Disease

Modern working patterns have changed considerably over recent decades.

Many occupations involve prolonged standing or prolonged sitting, both of which increase pressure within the leg veins.

Occupations commonly associated with increased venous pressure include:

Healthcare professionals
Hairdressers
Teachers
Retail workers
Hospitality staff
Factory employees
Drivers
Office workers

Standing still reduces the effectiveness of the calf muscle pump, while prolonged sitting impairs normal circulation in the legs. Over time, both situations increase venous pressure and may accelerate valve failure in susceptible individuals.

Regular movement throughout the working day allows the calf muscles to contract and assist blood returning towards the heart.

Hormonal Changes Can Influence Vein Function

Hormones influence both the venous wall and the connective tissues that support the venous system.

Progesterone relaxes smooth muscle within blood vessel walls, allowing veins to become more distensible. Oestrogen also affects connective tissue strength.

Periods of hormonal change that may contribute to earlier development of varicose veins include:

Puberty
Pregnancy
Hormonal contraception
Fertility treatment
Hormone replacement therapy

Hormonal changes rarely act alone but often accelerate venous disease in individuals with inherited valve weakness.

Pregnancy Increases Pressure Within the Venous System

Pregnancy is recognised as one of the most important risk factors for developing varicose veins in younger women.

Several physiological changes occur simultaneously:

Blood volume increases significantly.
Progesterone relaxes the vascular walls.
The enlarging uterus compresses the pelvic veins.
Pressure within the leg veins rises.

These changes may lead to:

Leg varicose veins
Vulval varicose veins
Pelvic venous insufficiency

Although some pregnancy-related veins improve following delivery, damaged valves generally do not recover fully. Symptoms may therefore return during future pregnancies or later in life.

Excess Weight Places Additional Pressure on the Veins

Body weight has a direct effect on venous pressure.

Excess abdominal weight increases pressure within the veins of the pelvis and lower limbs, making it more difficult for blood to return towards the heart.

Obesity has consistently been identified as an independent risk factor for chronic venous disease and may accelerate progression in patients who already have inherited valve weakness.

Maintaining a healthy weight cannot reverse damaged veins, but it may reduce symptoms and slow progression.

Physical Activity Supports Healthy Venous Circulation

Walking is one of the most beneficial forms of exercise for vein health.

Each contraction of the calf muscles compresses the deep veins, creating what is commonly known as the calf muscle pump. This mechanism assists blood returning towards the heart and reduces pressure within the superficial veins.

Activities that promote healthy circulation include:

Walking
Swimming
Cycling
Low impact aerobic exercise

Regular exercise also assists weight management and improves overall cardiovascular health.

Although exercise supports healthy circulation, it cannot repair damaged venous valves once reflux has developed.

Can Exercise or Weightlifting Cause Varicose Veins?

Exercise itself is not considered a cause of varicose veins.

Resistance training, running and other sporting activities do not damage healthy veins.

However, repeated increases in intra-abdominal pressure during heavy lifting may make underlying venous reflux more noticeable in individuals with weakened venous valves.

Athletes frequently have prominent superficial veins because reduced body fat makes healthy veins more visible beneath the skin.

Visible veins should not automatically be assumed to be varicose veins. A duplex ultrasound scan can distinguish between healthy superficial veins and veins affected by venous reflux.

Early Varicose Veins May Look Different

The large, twisted veins commonly associated with advanced varicose veins often develop gradually over several years. Younger patients may experience much subtler signs during the early stages of venous disease.

These may include:

A single raised vein on the calf or thigh
Small clusters of enlarged blue veins
Aching after prolonged standing
A feeling of heaviness towards the end of the day
Mild ankle swelling after work or long journeys
Itching over an area where veins later become visible
Veins that appear more prominent during hot weather or after exercise

Recognising these early changes allows venous insufficiency to be investigated before more advanced complications develop.

Younger People Often Delay Assessment

One of the reasons chronic venous disease progresses is that younger adults frequently dismiss the early symptoms.

Leg discomfort is often attributed to exercise, prolonged standing at work or general muscle fatigue. Visible veins may also be regarded as a cosmetic concern rather than evidence of underlying venous reflux.

As a result, patients commonly tolerate symptoms for several years before seeking specialist assessment.

Persistent aching, swelling or enlarging veins should not be regarded as a normal consequence of work, exercise or increasing fitness, particularly where there is a family history of varicose veins.

Modern Lifestyles May Contribute

Outside work, daily life has become increasingly sedentary.

Working from home, commuting by car and prolonged use of computers and mobile devices all reduce the amount of movement undertaken throughout the day.

Remaining seated for several hours allows blood to collect within the lower limbs, increasing venous pressure.

Simple lifestyle measures that support healthy circulation include:

Walking regularly throughout the day
Avoiding prolonged sitting or standing
Maintaining a healthy body weight
Remaining physically active
Elevating the legs after prolonged standing, where appropriate

These measures support venous circulation but cannot eliminate established venous reflux.

Exercise Performance and Recovery

Venous insufficiency can affect more than appearance.

Some younger patients notice symptoms during or after physical activity, particularly where prolonged exercise places additional demands on the calf muscle pump.

Symptoms may include:

Legs that feel unusually heavy during longer walks or runs
Aching after sporting activity
Reduced endurance when standing for prolonged periods
Increased discomfort following exercise rather than during it

These symptoms do not necessarily indicate poor fitness. They may reflect increased venous pressure caused by underlying valve dysfunction. Following successful treatment, many patients return to their usual sporting activities with improved comfort.

Long Journeys and Air Travel

Extended periods of immobility during flights, train journeys or long car journeys can temporarily increase symptoms in patients with venous insufficiency.

Remaining seated for several hours allows blood to pool in the lower-leg veins, resulting in increased swelling, aching, or heaviness.

Simple measures that encourage circulation include:

Standing and walking regularly during long journeys
Performing ankle and calf exercises while seated
Drinking adequate fluids
Wearing appropriately fitted compression stockings when advised by a vascular specialist

These measures improve venous return but do not replace treatment where significant venous reflux is present.

Varicose Veins Are More Than a Cosmetic Concern

Visible veins are often the reason younger patients first become aware of venous disease, but the cosmetic appearance represents only one aspect of the condition.

Untreated venous reflux may continue to progress, increasing pressure within the affected veins and surrounding tissues.

Potential complications include:

Persistent leg swelling
Skin pigmentation
Varicose eczema
Lipodermatosclerosis
Superficial thrombophlebitis
Bleeding from varicose veins
Venous leg ulcers

Early assessment allows these risks to be identified before more advanced chronic venous disease develops.

Confidence and Quality of Life

Although treatment decisions should always be based upon clinical assessment, the psychological effects of visible varicose veins should not be overlooked.

Younger adults frequently report avoiding shorts, skirts, swimming, holidays or sporting activities because they feel self-conscious about the appearance of their legs. Others become increasingly aware of discomfort during work or social activities that involve prolonged standing.

Improving symptoms and treating visible varicose veins can therefore benefit both physical comfort and quality of life.

Assessment Begins with Duplex Ultrasound

Visible veins alone do not determine whether treatment is appropriate.

The most important investigation is a duplex ultrasound scan, which provides detailed information about blood flow within both the superficial and deep venous systems.

Ultrasound assessment identifies:

The presence of venous reflux
Which veins are affected
Valve function
The severity of venous disease
The most appropriate treatment pathway

This examination also excludes other conditions that may produce similar symptoms.

Treatment Options

Significant advances in vascular medicine mean that most patients no longer require traditional vein stripping surgery.

Treatment is selected based on the ultrasound findings and the pattern of venous reflux.

Endovenous Laser Treatment (EVLT)

Laser energy is delivered into the affected vein using a fine catheter. Heat seals the vein closed, allowing blood to reroute through healthy veins.

Radiofrequency Ablation

Radiofrequency energy gently heats and closes the diseased vein with minimal trauma to surrounding tissues.

Medical Adhesive (Vein Glue)

Medical adhesive closes the vein without heat or tumescent anaesthetic, allowing many patients to resume normal activities quickly.

Foam Sclerotherapy

A specialised foam is injected into affected veins under ultrasound guidance. The treated vein gradually seals and is absorbed by the body over time.

Microsclerotherapy

Microsclerotherapy remains an effective treatment for thread veins and smaller superficial veins that do not require endovenous intervention.

Most modern procedures are performed under local anaesthetic on a walk-in, walk-out basis with minimal recovery time.

Does Treatment Prevent Future Varicose Veins?

Treatment closes or removes veins affected by venous reflux, relieving symptoms and improving circulation through healthier veins.

However, treatment cannot alter inherited factors that contribute to chronic venous disease. Patients with a strong family history may develop new areas of venous reflux over time, particularly if additional risk factors such as pregnancy or prolonged standing are present.

Regular follow-up and early assessment of new symptoms help identify any future vein problems before they become more advanced.
