varicose veins risk reduction
Informed by recognized medical guidance
Overview
Varicose veins are swollen, twisted veins that usually appear on the legs. They happen when the small valves inside veins become weak or damaged, allowing blood to flow backward and pool. This makes the veins bulge and become visible under the skin.
Key facts
- Varicose veins are very common, affecting about 1 in 3 adults at some point.
- They are often harmless, but they can cause aching, heaviness, and skin changes.
- Regular movement, a healthy weight, and elevating your legs can lower your risk and ease symptoms.
Yes, varicose veins are very common. About one in three adults may develop them during their lifetime.
They affect both men and women, but women are more likely to develop them. The risk increases with age, during pregnancy, and if you have a family history of varicose veins.
Symptoms
- If a varicose vein breaks and bleeds heavily, call your local emergency number immediately.
- If you have sudden painful swelling in one leg, chest pain, or trouble breathing, call emergency services right away, as these can be signs of a blood clot.
- ⚠If the skin over a varicose vein becomes red, hot, or very tender, seek same-day care.
- ⚠If a vein becomes hard, swollen, or painful, contact your healthcare provider urgently.
Common symptoms
- Aching, heavy, or tired legs, especially after standing for a long time
- Swelling in the lower legs and ankles
- Itching or burning around the affected veins
- Visible bulging, twisted veins that look dark purple or blue
- Skin dryness, discoloration, or a feeling of warmth near the veins
Symptoms in children
- Varicose veins are rare in children. If they appear, they may be related to a blood vessel condition present at birth, so a healthcare provider should check any unusual veins in a child.
Symptoms in older adults
- As you age, veins naturally lose flexibility, so varicose veins become more likely.
- Older adults may have more noticeable swelling, skin changes, and leg discomfort from varicose veins.
Causes
Main causes
- Weak or damaged valves inside the veins
- Increased pressure in the veins of the legs, often from standing or sitting for long periods
- Blood flowing backward and pooling because of gravity and weak vein walls
Risk factors
- Family history of varicose veins
- Age, as veins lose elasticity over time
- Being female, especially due to hormonal changes during pregnancy or menopause
- Pregnancy, which increases blood volume and pressure in the legs
- Obesity, which adds extra pressure on leg veins
- Prolonged standing or sitting without moving
- Lack of regular exercise
When to see a doctor
See a doctor urgently if:
- Sudden severe pain or swelling in one leg
- Red, hot, or very tender skin over a vein
- A varicose vein that bleeds and is difficult to stop
- A hard, painful vein, especially if your leg swells
Book a routine appointment if:
- Aching, heaviness, or tiredness in your legs that affects your daily activities
- Visible bulging veins that bother you or cause concern about your health
- Skin changes such as dryness, itching, or discoloration around the veins
Diagnosis
A healthcare provider usually diagnoses varicose veins by looking at and feeling your legs while you stand. They will also ask about your symptoms, lifestyle, and family history. In some cases, they may recommend an imaging test to check how blood is flowing through the veins.
Tests that may be done
- A physical exam of your legs while standing
- A duplex ultrasound scan, which uses sound waves to see blood flow and vein damage
What to expect at your appointment
The diagnosis is usually quick and painless. You may be asked to stand for part of the exam. If an ultrasound is needed, you will lie on a table while a small handheld device glides over your leg with a little gel.
Treatment
Treatment for varicose veins focuses on relieving symptoms, improving skin health, and preventing complications. Many effective options are available, from simple self-care steps to minimally invasive procedures.
Self-care at home
- Exercise regularly to improve blood circulation in your legs
- Elevate your legs when resting to help blood flow back toward your heart
- Wear compression stockings if your healthcare provider recommends them
- Avoid long periods of standing or sitting; take short walks throughout the day
- Maintain a healthy weight to reduce pressure on your veins
Medical treatments
Medical treatments for varicose veins include minimally invasive procedures that close or remove affected veins. These are done by a specialist and include laser therapy, radiofrequency ablation, and sclerotherapy, which uses a foam or liquid injected into the vein. Your healthcare provider will explain the options best suited for your situation.
When is surgery considered?
Surgery may be an option for larger varicose veins when other treatments have not helped. The type of surgery depends on your individual case. Your healthcare provider will discuss the benefits and risks with you before recommending it.
Living with this condition
Living with varicose veins often involves simple habits to reduce discomfort and slow the condition's progression. These habits can become part of your daily routine and usually make a big difference.
Lifestyle tips
- Take a daily walk and avoid standing or sitting for long stretches
- Put your feet up whenever you can, ideally above the level of your heart
- Wear comfortable clothes and shoes; ask your healthcare provider about compression stockings
- Try not to cross your legs for long periods
Diet and exercise
A healthy diet rich in fiber and low in salt can help reduce leg swelling. Regular exercise, especially walking, swimming, or cycling, keeps your leg muscles active and supports healthy blood flow.
Mental health and emotional wellbeing
Varicose veins can affect how you feel about your legs, especially if they are very visible. It is normal to feel self-conscious or worried. Talk to your healthcare provider about these feelings, and ask if there are cosmetic treatment options that could help your confidence.
Prevention
You cannot always prevent varicose veins, but you can reduce your risk. Staying active, keeping a healthy weight, and avoiding long periods of standing or sitting are the most effective steps you can take.
Screening programmes
There is no routine screening test for varicose veins, but your healthcare provider can check your veins during a regular physical exam if you have concerns.
Complications
If left untreated
- Mild complications can include skin dryness, itching, and discoloration.
- Some people may develop a condition called superficial thrombophlebitis, which is a painful, swollen vein just under the skin.
- More serious complications, like deep vein thrombosis or skin ulcers, are less common but can occur if varicose veins are severe and left untreated.
Long-term outlook
Most varicose veins do not cause serious health problems. With self-care and, if needed, medical treatment, most people find good relief from symptoms and can successfully prevent complications. Your healthcare provider can help you create a plan that works for you.
