screening for varicose veins

Overview

Varicose veins are swollen, twisted veins that you can see just under the skin, usually in your legs. Screening means checking for these veins and any related problems. It helps you understand whether you need treatment or just some simple self-care.

Yes, varicose veins are very common. About 1 in 3 adults may develop them at some point in their life.

They are more common in women, older people, pregnant women, and people who spend long periods standing or sitting.

Symptoms

Common symptoms

• Aching or heavy feeling in your legs
• Swelling in your ankles or lower legs
• Itching or burning around the veins
• Visible veins that are blue or dark purple and look twisted or bulging

Symptoms in children

• Varicose veins are rare in children. If they appear, they may be linked to a birth defect in the veins, and a doctor should check them.

Symptoms in older adults

• Symptoms are the same as for other adults, but older people may also have skin changes, such as dry, thin, or discolored skin near the veins.
• They are more likely to develop leg ulcers or bleeding from a varicose vein.

Causes

Main causes

• Weak vein walls that stretch and lose their shape
• Damaged one-way valves inside the veins, which let blood flow backward and pool

Risk factors

• Getting older
• Being pregnant
• Having a family history of varicose veins
• Being overweight or obese
• Standing or sitting for long periods without moving

When to see a doctor

See a doctor urgently if:

• If you have any signs of a blood clot, such as a swollen, painful, hot calf
• If a varicose vein is bleeding and won't stop

Book a routine appointment if:

• If you have aching, heaviness, or swelling in your legs that bothers you
• If you notice skin changes, like darkening or an ulcer near a vein

Diagnosis

A doctor can usually tell if you have varicose veins by looking at your legs while you stand. They will also ask about your symptoms and risk factors.

Tests that may be done

• An ultrasound scan, called a Doppler ultrasound, to check blood flow in your veins
• In some cases, a special X-ray or other imaging test may be used to get a clearer picture

What to expect at your appointment

The exam is simple and painless. You may be asked to stand for a few minutes. If you have an ultrasound, a small handheld device is moved over your leg with some gel. There is no needle and no pain.

Treatment

Treatment depends on how bad your symptoms are, whether you have complications, and what you prefer. Many people do well with self-care alone. If treatment is needed, there are several safe and effective options.

Self-care at home

• Exercise regularly, like walking or swimming, to improve blood flow
• Elevate your legs when resting, ideally above the level of your heart
• Avoid standing or sitting for long stretches; take short breaks to move
• Wear compression stockings if advised by a doctor or pharmacist

Medical treatments

For more bothersome veins, doctors may offer procedures such as laser treatment, radiofrequency treatment, sclerotherapy (injecting a special solution into the vein), or minimally invasive surgery to close or remove the damaged vein. These treatments are done by specially trained doctors or surgeons.

When is surgery considered?

Surgery may be recommended if you have severe symptoms, skin ulcers, or bleeding from a varicose vein that does not improve with other treatments.

Living with this condition

Varicose veins can be managed with simple daily habits. Keep your legs moving, avoid long periods of standing, and elevate your legs whenever you can.

Lifestyle tips

• Maintain a healthy weight to reduce pressure on your veins
• Wear loose clothing and avoid tight belts or socks that restrict blood flow
• If you stand at work, shift your weight and walk a few steps every now and then

Diet and exercise

A balanced diet with plenty of fiber helps prevent constipation, which can strain your veins. Regular exercise, especially walking and swimming, strengthens your leg muscles and helps push blood back to your heart.

Mental health and emotional wellbeing

Varicose veins can make some people feel self-conscious about their legs. It is normal to feel this way. Talking to your doctor about treatment options can help you feel more comfortable.

Prevention

You cannot always prevent varicose veins, especially if they run in your family. But you can reduce your risk and slow their progression by staying active, maintaining a healthy weight, and avoiding long periods of standing or sitting.

Screening programmes

Routine screening for varicose veins is not needed for everyone. Your doctor may check your legs during a regular appointment if you have risk factors or symptoms. If you are concerned, you can ask for an assessment.

Complications

If left untreated

• Skin changes, such as dryness, thinning, or darkening
• Leg ulcers that can be painful and slow to heal
• Bleeding from broken varicose veins
• Blood clots (deep vein thrombosis) in rare cases

Long-term outlook

With self-care and the right treatment, most people with varicose veins feel better and avoid serious problems. Even if your veins do not completely disappear, symptoms can be managed well.
