A vein screening is a simple, painless test that uses ultrasound to look at the veins in your legs or other parts of your body. It helps check for problems like varicose veins or blood clots. The test uses sound waves to create pictures of your veins and how blood flows through them. It does not use radiation and is safe.
Key facts
Vein screenings are very common. Many people have them to check for varicose veins or to investigate symptoms like leg swelling, pain, or skin changes.
Vein screenings are done for adults of any age who have symptoms of vein problems, or who have risk factors such as a family history of varicose veins or blood clots, being overweight, standing or sitting for long periods, or having had a previous clot.
A vein screening is done with a test called a venous ultrasound. It uses a small handheld device (probe) that sends sound waves into your body to create pictures of your veins and measure blood flow.
You lie on an exam table. A clear gel is put on your skin over the area being checked. The technician gently presses a small probe against your skin and moves it around. You may feel slight pressure, but it is not painful. The test usually takes 15 to 45 minutes. You can go home right after and return to normal activities.
Treatment for vein problems depends on the type and severity of the issue. Many mild cases can be managed with lifestyle changes and self-care. If needed, there are medical procedures that can be done. Your doctor will discuss the best options for you.
Most people with vein problems can lead a full life. Simple habits like wearing compression stockings, taking breaks from sitting, and moving your legs can make a big difference. If you have a vein screening, it gives you and your doctor a clear picture of what's going on so you can manage it well.
You cannot always prevent vein problems, especially if you have a family history. But you can reduce your risk and slow the progression by staying active, maintaining a healthy weight, and avoiding long periods of standing or sitting. If you have a job that requires sitting or standing, take regular breaks to move around.
Screening is not recommended for everyone, but you may be offered a vein screening if you have symptoms or risk factors. Talk to your doctor if you're concerned.
Most vein problems are not serious and can be managed well. With proper care and treatment, symptoms usually improve, and complications are rare. If a vein screening shows issues, there are many effective ways to treat them and keep your legs healthy.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
For more severe or bothersome vein problems, treatments include: using heat or laser to close off damaged veins (endovenous ablation), injecting a chemical that makes the vein collapse (sclerotherapy), or small cuts to remove larger varicose veins (phlebectomy). These are usually done as day procedures and have quick recovery times.
Surgery may be considered if the vein problem is severe, causing pain or skin ulcers, and other treatments haven't worked. The most common surgery is called 'ligation and stripping', where the vein is tied off and removed. This is less common now because less invasive options are available.
Eating a balanced diet with plenty of fibre (fruits, vegetables, whole grains) helps prevent constipation, which can put pressure on your veins. Regular exercise like walking, cycling, or swimming improves your circulation and helps keep your leg muscles strong. These muscles help push blood back up to your heart.
Having visible varicose veins or chronic leg pain can affect how you feel about your body. It's normal to feel frustrated or self-conscious. Talking to a healthcare provider or a counsellor can help. Remember that treatment can improve both symptoms and appearance.
