questions to ask before varicose veins

Overview

Varicose veins are swollen, twisted veins that you can see just under the surface of the skin. They most often happen in the legs. They occur when the valves inside your veins become weak or damaged, causing blood to pool and the vein to stretch.

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

Varicose veins can affect anyone, but they are more common in women, people over 40, those who are overweight, pregnant, or stand for long periods. Family history also plays a role.

Symptoms

Common symptoms

• Aching, heavy, or tired legs
• Swelling in the ankles and feet
• Burning, throbbing, or cramping in the legs
• Itching around the vein
• Skin changes like redness or dry, thin skin near the vein

Symptoms in children

• Varicose veins are rare in children. If they appear, they may be linked to a condition called chronic venous insufficiency. Always check with a doctor.

Symptoms in older adults

• Same symptoms as adults, but older adults may also have more swelling, skin ulcers (sores), or bleeding from the vein. Skin around the ankle may become hard or discoloured.

Causes

Main causes

• Weak or damaged valves in the veins that let blood flow backward and pool
• Weakened vein walls that stretch under pressure

Risk factors

• Age (over 40)
• Being female (hormonal changes, pregnancy)
• Obesity
• Standing or sitting for long periods
• Family history
• Previous deep vein thrombosis (DVT)

When to see a doctor

See a doctor urgently if:

• If you have sudden severe pain and swelling in one leg
• If a varicose vein bursts and bleeds
• If you have signs of infection (redness, warmth, fever)

Book a routine appointment if:

• If varicose veins cause daily discomfort that affects your quality of life
• If you notice skin ulcers, swelling that doesn't improve
• If you are concerned about the appearance and want treatment options

Diagnosis

A doctor will start by asking about your symptoms and examining your legs while you stand. They may also use a simple ultrasound test to see how blood is flowing in your veins.

Tests that may be done

• Physical exam
• Duplex ultrasound (a painless scan to check blood flow and vein health)

What to expect at your appointment

The doctor will look for swelling, skin changes, and any visible veins. They may ask you questions about your pain and daily activities. The ultrasound is done with a small wand on your skin – it's not painful. Based on the results, you will discuss treatment options.

Treatment

Treatment for varicose veins depends on how much they bother you. Many people manage with self-care. If you need more, there are several minimally invasive treatments and sometimes surgery. Your doctor will help you choose based on your symptoms and the size of the veins. Before any treatment, it's important to ask questions like: What are the benefits and risks? How long is recovery? Will the veins come back? What results can I expect?

Self-care at home

• Elevate your legs above heart level for 15-20 minutes several times a day
• Wear compression stockings (graduated compression, ask your pharmacist or doctor for the right strength)
• Exercise regularly – walking is great for circulation
• Avoid sitting or standing for long periods; move every 30 minutes
• Maintain a healthy weight
• Don't cross your legs when sitting

Medical treatments

If self-care is not enough, your doctor may offer treatments such as endothermal ablation (using heat to close the vein), sclerotherapy (injecting a solution to close the vein), phlebectomy (removing small veins through tiny cuts), or vein stripping for larger veins. These are usually done as day procedures. No specific drug names are recommended here.

When is surgery considered?

Surgery (vein stripping or ligation) is less common nowadays because of newer, less invasive options. It may still be used in some cases, such as very large or twisted veins. Ask your doctor about the risks and recovery.

Living with this condition

You can live comfortably with varicose veins by making small changes. Elevate your legs when resting, wear compression stockings if advised, and stay active. Check your skin regularly for any changes.

Lifestyle tips

• Move regularly – do not sit or stand still for hours
• When resting, put your feet up – ideally above heart level
• Wear comfortable shoes and avoid tight clothing around the waist or legs
• If you have a desk job, take short walks every 30 minutes

Diet and exercise

Eat a balanced diet rich in fibre (to prevent constipation) and low in salt (to reduce swelling). Stay hydrated. Exercise like walking, swimming, or cycling helps improve blood flow in your legs.

Mental health and emotional wellbeing

Varicose veins can affect your confidence or cause worry about complications. It's normal to feel self-conscious. Talking to your doctor can help you understand your options. If you feel anxious or down, speak to a healthcare professional. You are not alone.

Prevention

You cannot always prevent varicose veins, especially if you have a family history. But you can reduce your risk by staying active, maintaining a healthy weight, and not sitting or standing for long periods. Also, avoid crossing your legs when sitting and avoid tight clothing.

Screening programmes

There is no routine screening for varicose veins. You should check your legs yourself and see a doctor if you have concerns.

Complications

If left untreated

• Leg ulcers (open sores that heal slowly)
• Bleeding from a varicose vein
• Thrombophlebitis (inflamed, clotted vein)
• Deep vein thrombosis (DVT) – a serious blood clot in a deep vein

Long-term outlook

The outlook for varicose veins is generally good. Most people can manage symptoms with self-care and lifestyle changes. Even if you need treatment, newer techniques have high success rates and quick recovery. Varicose veins rarely lead to serious problems if you take care of your legs and see a doctor when needed.
