preventing varicose veins

Overview

Varicose veins are swollen, twisted veins that usually appear blue or dark purple under the skin, most often in the legs. They happen when the small valves inside your veins stop working properly, allowing blood to flow backward and pool in the vein.

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

Anyone can get varicose veins, but they are more common in women, people over 40, pregnant women, and those with a family history or who stand or sit for long hours at work.

Symptoms

Common symptoms

• Aching, heavy or tired legs
• Swelling in the lower legs and ankles
• Bulging, twisted blue or dark purple veins
• Itching or burning around the veins
• Feeling of heaviness or restlessness in the legs

Symptoms in children

• Varicose veins are rare in children. If you notice them, talk to your pediatrician to rule out any underlying health condition.

Symptoms in older adults

• Older adults may experience the same symptoms as others, but skin changes such as dryness, thinning, or darkened areas can appear. Pain and swelling may also be more noticeable.

Causes

Main causes

• Weakened valves inside the veins that let blood flow backward
• Weak or damaged vein walls that stretch and lose flexibility
• Increased pressure in the leg veins from standing or sitting for long periods

Risk factors

• Being female and pregnant
• Age over 40
• Family history of varicose veins
• Overweight or obesity
• Jobs that require long periods of standing or sitting
• Lack of physical activity

When to see a doctor

See a doctor urgently if:

• Bleeding from a varicose vein that does not stop
• Sudden severe swelling or pain in your leg
• Signs of a blood clot, like a hot, red, swollen vein

Book a routine appointment if:

• If your legs feel heavy or achy often
• If you are concerned about how your veins look
• If you have skin changes or ulcers near your ankles

Diagnosis

Your doctor will ask about your symptoms, look at your legs, and feel your veins. They may also use an ultrasound scan to see how your veins are working.

Tests that may be done

• Physical examination
• Medical history review
• Duplex ultrasound scan of the legs (a painless imaging test)

What to expect at your appointment

The diagnosis is usually simple and quick. An ultrasound may take about 15 to 30 minutes. You will be able to go home right after.

Treatment

Treatment for varicose veins depends on your symptoms, how severe they are, and if you have any complications. Many people only need self-care and leg exercises. Others may benefit from procedures or surgery.

Self-care at home

• Keep your legs raised whenever possible, especially after long periods of sitting or standing
• Exercise regularly, such as walking, to improve circulation
• Wear compression stockings if your doctor recommends them
• Take short walks every hour if you sit or stand at work
• Avoid crossing your legs when sitting

Medical treatments

If self-care is not enough, a specialist may offer treatments such as injection therapy, laser therapy, or other minimally invasive procedures. These methods close off the affected vein so blood is rerouted through healthier veins. There are also medicines that can help symptoms, but your doctor will discuss the best option for you based on your health history.

When is surgery considered?

Surgery is less commonly needed today. It may be considered if the vein is very large, causing pain, or leading to ulcers or bleeding. Your vascular specialist will explain if surgery is necessary for your situation.

Living with this condition

You can manage varicose veins day-to-day by moving regularly, elevating your legs, and wearing comfortable clothing. Avoid standing still for a long time. If your legs swell, try to raise them above heart level when you rest.

Lifestyle tips

• Aim for at least 30 minutes of moderate activity most days, such as brisk walking or cycling
• Maintain a healthy weight to reduce pressure on your leg veins
• If you sit at a desk, take breaks to walk and stretch your legs
• Wear loose, non-restrictive clothing and avoid high heels if they make leg pain worse

Diet and exercise

Eating a balanced diet high in fiber and low in salt can help prevent constipation and water retention, both of which can worsen varicose veins. Regular exercise, especially walking, strengthens your calf muscles and helps pump blood up your legs.

Mental health and emotional wellbeing

Varicose veins can sometimes make you feel self-conscious or affect your confidence. If your appearance bothers you, talk to your doctor about treatment options. It is normal to have these feelings, and support can help.

Prevention

You cannot always prevent varicose veins, especially if you have a family history. But you can reduce your risk with regular exercise, healthy weight, avoiding long periods of sitting or standing, and elevating your legs when you rest.

Complications

If left untreated

• Skin discoloration and hardening
• Open sores (ulcers), usually near the ankles
• Bleeding from a ruptured varicose vein
• Development of a superficial blood clot (phlebitis) that can cause pain and swelling

Long-term outlook

For most people, varicose veins are not life-threatening. With the right self-care and medical support, symptoms can be managed well, and serious complications are uncommon. Many people find that simple lifestyle changes make a big difference. If needed, modern treatments are safe and effective.
