16754 Venous Disease

Overview

Venous disease is a group of conditions that affect the veins, the blood vessels that carry blood back to your heart. The most common types include varicose veins (swollen, twisted veins), chronic venous insufficiency (when veins have trouble sending blood from the legs back to the heart), and deep vein thrombosis (a blood clot in a deep vein, usually in the leg).

Yes, venous disease is very common. About one in three adults may have varicose veins, and chronic venous insufficiency affects many people, especially as they get older.

Anyone can develop venous disease, but it is more likely as you age. It also occurs more often in women, during pregnancy, in people who are overweight, and in those who spend long hours sitting or standing. A family history of vein problems also raises the chances.

Symptoms

Common symptoms

• Swelling in the lower legs and ankles, especially after standing for long periods
• A heavy, aching, or tired feeling in the legs
• Visible, bulging, or twisted veins (varicose veins)
• Itching or a burning sensation over the veins
• Darkening or thickening of the skin on the ankles or lower legs
• Leg cramps, especially at night
• Restless legs or an uncomfortable urge to move the legs

Symptoms in children

• Venous disease is rare in children. When it happens, it is usually due to a birth defect or an injury affecting the veins. Symptoms may include swelling, visible veins, or pain in a leg.

Symptoms in older adults

• Swelling and dull pain in the legs are common, along with skin changes such as darkening, dryness, and itching.
• Older adults are more likely to develop open sores (ulcers) on the lower leg or ankle if venous disease is not managed.
• They may also feel unsteady or find it harder to walk because of heaviness and swelling.

Causes

Main causes

• Weak or damaged vein walls, which cause the veins to stretch and lose elasticity.
• Faulty one-way valves inside the veins, which allow blood to flow backward and pool instead of moving upward to the heart.
• Blood clots that damage the valves or block the vein, leading to chronic venous insufficiency.

Risk factors

• Getting older
• Being female (hormonal changes, especially during pregnancy, can affect vein walls)
• Being overweight or obese
• Having a family history of varicose veins or DVT
• Standing or sitting for long periods without moving
• A previous blood clot in a leg vein
• Smoking
• Inactive lifestyle

When to see a doctor

See a doctor urgently if:

• If you have symptoms of a blood clot in the leg (sudden swelling, pain, warmth, redness in one leg).
• If you have sudden chest pain, trouble breathing, or you cough up blood.
• If a varicose vein breaks and bleeds heavily.

Book a routine appointment if:

• If you have persistent leg swelling, pain, or heaviness that affects your daily life.
• If you notice skin color changes, itching, or a sore on your leg that is not healing.
• If varicose veins are causing you discomfort or making you self-conscious.
• If you have questions about your risk of developing vein problems, especially if you have a family history.

Diagnosis

A healthcare provider will usually diagnose venous disease by listening to your symptoms, examining your legs (looking for swelling, skin changes, or visible veins), and checking your pulses. They may also ask about your medical and family history.

Tests that may be done

• Ultrasound (doppler ultrasound) — this painless test uses sound waves to show how blood flows in your veins and whether the valves are working properly.
• A venogram (X-ray with contrast dye) — this is rarely needed but may be used in special cases to map the veins.
• Blood tests — these can help rule out other causes of swelling (such as heart, kidney, or thyroid problems) or check for a blood clotting tendency.

What to expect at your appointment

Your appointment usually starts with a discussion of your symptoms and lifestyle. The physical exam is quick and simply involves looking at and feeling your legs. If an ultrasound is needed, a gel is applied to your skin, and a small probe is moved over the area — it is painless and takes about 15 to 30 minutes. You will receive clear results and a plan with the next steps.

Treatment

Treatment for venous disease depends on the type and severity of the problem. For many people, simple self-care measures and wearing compression stockings are enough. If symptoms are more severe or there are complications, medical procedures can help close off or remove damaged veins. Blood-thinning medications may be advised for blood clots, but only a doctor can prescribe them.

Self-care at home

• Elevate your legs above the level of your heart for 30 minutes, several times a day.
• Move regularly — walk or do calf exercises to help pump blood out of your legs.
• Avoid standing or sitting still for long periods; take short breaks to walk.
• Wear compression stockings if recommended by a healthcare provider, as they support the veins and reduce swelling.
• Keep your legs clean and moisturized, and avoid injuring the skin.
• Maintain a healthy weight to reduce pressure on your veins.

Medical treatments

Medical treatments for venous disease are usually done by a specialist (such as a vascular doctor). They include minimally invasive procedures like laser or radiofrequency ablation, which uses heat to close a damaged vein; sclerotherapy, where a special solution is injected to make a vein scar and close; and microphlebectomy, where small cuts are made to remove varicose veins. During surgery, the vein may be stripped through small incisions. All these options aim to improve blood flow and relieve symptoms. Your doctor will explain which approach is appropriate for you.

When is surgery considered?

Surgery may be recommended if you have severe chronic venous insufficiency, large varicose veins that bleed or cause ulcers, or if a blood clot is present in a way that is dangerous or not improving with other treatment. The exact operation depends on your specific condition and is always discussed with you beforehand.

Living with this condition

Living with venous disease often involves small daily habits. Try to get your legs moving every half hour during the day, take walks, and put your feet up when you can. Wearing compression stockings can feel strange at first, but many people find they reduce pain and swelling and are worth the effort. Keep your skin well moisturized and check your legs for any new sores or color changes.

Lifestyle tips

• Take regular walks or do low-impact activities like swimming, cycling, or yoga.
• Stand up and stretch often if you have a desk job; slow marching in place can also help.
• If you are standing for work, shift weight regularly and stand on your toes or rock onto your heels.
• Lose weight if you are overweight — even a small reduction can ease leg symptoms.
• Stop smoking to improve blood flow and reduce the risk of blood clots.

Diet and exercise

A balanced diet rich in fibre, vegetables, and lean protein can help prevent constipation and support a healthy weight. Exercise is key — physical activity strengthens the calf muscles, which act as a pump to push blood upward. Even 20 to 30 minutes of walking most days makes a real difference.

Mental health and emotional wellbeing

Living with a chronic condition can be frustrating and worrying, especially if you have pain or visible changes in your legs. It is normal to feel self-conscious or anxious. Talking to your healthcare team about your feelings can help. Remember that you are not alone, and many people find relief from symptoms with proper care.

Prevention

You cannot always prevent venous disease, especially if you have a family history. However, you can lower your risk or slow its progression by staying active, maintaining a healthy weight, avoiding long periods of sitting or standing, elevating your legs when resting, and not smoking. If you have already developed vein problems, these steps also help stop them from getting worse.

Screening programmes

There is no routine screening test for venous disease in the general population. However, if you have risk factors (such as a previous blood clot, strong family history, or symptoms like leg swelling), your doctor may suggest an ultrasound to check your veins. It is always a good idea to mention any concerns during a regular check-up.

Complications

If left untreated

• Skin changes such as darkening, thickening, or hardening of the skin on the legs.
• Open sores (venous ulcers) on the lower legs or ankles that are painful and slow to heal.
• Inflammation of a superficial vein (phlebitis), which causes pain and redness.
• Deep vein thrombosis (DVT) — a blood clot that can travel to the lungs and cause a life-threatening pulmonary embolism.
• Bleeding from a varicose vein if it is injured or under high pressure.

Long-term outlook

Most people with venous disease live full, active lives. With the right self-care, medical advice, and treatments, symptoms like swelling and pain can be greatly reduced. Serious complications are uncommon when the condition is monitored. The outlook is generally very positive, especially when you work together with your healthcare team.
