Varicose veins are swollen, twisted veins that you can see just under the skin. They usually happen in the legs and can look blue or dark purple.
Key facts
Yes, varicose veins are very common. About 1 in 4 adults may have them.
Anyone can get varicose veins, but they are more common in women, older people, and those who stand or sit for long periods.
A doctor can often diagnose varicose veins by looking at your legs while you stand. They may order a special ultrasound to check the veins deeper inside and see how blood is flowing.
During an ultrasound, you will lie down or stand while a small handheld device (transducer) is moved over your leg. There is no pain, and the test takes about 30 minutes. The results help your specialist decide the best treatment for you.
Treatment for varicose veins aims to relieve symptoms, prevent complications, and improve appearance. Not all varicose veins need treatment. Options range from lifestyle changes to medical procedures.
Medical treatments include minimally invasive procedures such as laser or radiofrequency ablation (using heat to seal the vein), sclerotherapy (injecting a solution to close the vein), or phlebectomy (removing the vein through small cuts). These are done by a specialist and can be done in a clinic with local anaesthetic.
Most people with varicose veins can live a normal life. Simple measures like wearing compression stockings, taking breaks to move, and elevating your legs can help manage symptoms.
A diet rich in fibre and low in salt can help prevent constipation and swelling. Gentle exercise like walking, swimming, or cycling improves circulation, especially in your legs.
There is no sure way to prevent varicose veins, but you can reduce your risk by keeping a healthy weight, moving regularly, and avoiding long periods of standing or sitting.
There is no routine screening for varicose veins. See your doctor if you have symptoms or concerns.
For most people, varicose veins do not cause serious problems. With proper care and, if needed, treatment, symptoms can be well managed, and complications are rare.
