17604 Vascular Disease

Overview

Vascular disease is a broad term for conditions that affect your blood vessels — the tubes that carry blood around your body. Your arteries carry oxygen-rich blood away from your heart, and your veins carry blood back. When these vessels become narrowed, blocked, weak, or damaged, blood flow can be reduced, which can cause symptoms like pain, swelling, or, in serious cases, heart attack or stroke. This includes conditions like peripheral artery disease (narrowed leg arteries), deep vein thrombosis (a blood clot in a vein), varicose veins, and aneurysms (a bulging, weakened vessel wall).

Yes, vascular conditions are very common, especially in older adults. Many people live with vascular disease without knowing it, because early signs can be mild — but it is a serious and treatable group of conditions.

Vascular disease can affect anyone, but it becomes more common with age — especially after age 50. You are at higher risk if you smoke, have diabetes, high blood pressure, high cholesterol, or a family history of vascular problems. It also affects men slightly earlier than women, though women catch up after menopause.

Symptoms

Common symptoms

• Leg pain, cramping, or tiredness when walking (which usually goes away with rest)
• Numbness, tingling, or coldness in your feet or legs
• Swelling in your legs, ankles, or feet
• Visible, bulging, twisted veins near the surface of the skin (varicose veins)
• Heaviness, aching, or fatigue in your legs after standing
• Changes in skin color on your legs — pale, bluish, or shiny skin
• Wounds or sores on your feet or legs that are slow to heal

Symptoms in children

• Vascular disease is rare in children, but when it happens it may show as birthmarks, abnormal lumps, or an unusually large limb.
• Children can also get blood clots (often related to an illness, injury, or medical device).
• If you notice a swollen, painful limb or a hard string-like vein, seek medical care promptly.

Symptoms in older adults

• Leg pain that is easy to dismiss as 'just getting older' — but it may signal narrow arteries.
• Swelling in both legs, which could relate to heart or vein problems.
• Skin changes — thin, tight, shiny, or discolored skin on the lower legs.
• Aching or burning in the feet, especially at night.
• Memory or balance changes can sometimes be related to reduced blood flow to the brain.

Causes

Main causes

• Atherosclerosis — the buildup of fatty deposits (plaque) inside artery walls, narrowing them over time
• Blood clots — these can block a vessel, either where they form or after traveling from another part of the body
• Damage to vessel walls from high blood pressure or other conditions
• Weakening of the vessel wall, leading to an aneurysm
• Inflammation of blood vessels (vasculitis), which is less common

Risk factors

• Smoking or using tobacco
• Diabetes (especially if blood sugar is poorly controlled)
• High blood pressure
• High cholesterol
• Being overweight or physically inactive
• A family history of heart disease, stroke, or vascular disease
• Age over 50
• A sedentary lifestyle or sitting for very long periods

When to see a doctor

See a doctor urgently if:

• If you notice any of the 'urgent' symptoms listed above — for example, a warm, swollen, painful leg, a bulging tender lump, or a non-healing ulcer — see a doctor today.
• If you have new or worsening chest pain with shortness of breath, call your local emergency number right away.

Book a routine appointment if:

• If you have leg pain when walking that eases with rest, see your general practitioner.
• If you have swelling or varicose veins that are bothering you or getting worse, book an appointment.
• If you have a family history of vascular disease and are worried, mention it at your next check-up.
• If you have diabetes or high blood pressure, keep your regular follow-ups — your doctor will check your circulation.

Diagnosis

Your doctor will start by asking about your symptoms, your medical history, and whether you have any risk factors. They will examine you — often feeling the pulses in your feet and legs, checking blood pressure, and listening to your arteries. Based on that, they may order tests.

Tests that may be done

• Ankle-brachial index (ABI) — compares blood pressure in your ankle with your arm to check blood flow to your legs
• Ultrasound scan — uses sound waves to look inside your blood vessels and check for narrowing or blockages
• Blood tests — to check cholesterol, blood sugar, and signs of inflammation or clotting
• CT or MRI scans — for more detailed images, especially for the abdomen, chest, or head
• Angiography — a special X-ray using a dye to see the inside of blood vessels, if needed

What to expect at your appointment

Diagnosis is usually straightforward. Some tests are simple and painless; others may involve a small needle or lying in a scanner. Your doctor will explain each step and what they are looking for. You will get results in a follow-up appointment — take a family member or friend with you if you can.

Treatment

Treatment for vascular disease depends on which vessels are affected and how severe it is. The main goals are to relieve symptoms, slow or stop the disease, and prevent complications such as stroke, heart attack, or tissue damage. Treatment always starts with lifestyle changes, and may include medicines and, in certain cases, procedures to widen or repair vessels.

Self-care at home

• Quit smoking — this is the single best thing you can do for your blood vessels.
• Walk regularly — even short, daily walks help improve circulation and build up your walking distance.
• Keep your feet clean and dry — check them daily for cuts, blisters, or sores, especially if you have diabetes.
• Elevate your legs when sitting or lying down if you have swelling or varicose veins.
• Wear compression stockings if recommended by your doctor — they help veins push blood upward.
• Maintain a healthy weight — even a small loss can reduce symptoms.
• Take breaks from sitting — stand up and move every hour, especially on long trips.

Medical treatments

Your doctor may prescribe medicines to lower blood pressure, reduce cholesterol, prevent blood clots, or control blood sugar in people with diabetes. Some medicines help widen blood vessels or relieve pain. Always take them exactly as prescribed. If you have a blood clot, you may be given blood-thinning medicine for a few months or longer. Never change or stop medicines without talking to your doctor.

When is surgery considered?

If a vessel becomes severely narrowed or an aneurysm becomes large or painful, a specialist may recommend a procedure. This can be angioplasty (inserting a small balloon to widen the vessel, often with a tiny metal tube called a stent) or surgery to bypass the blocked area. The choice depends on your individual situation — your doctor will explain the options and the risks and benefits.

Living with this condition

Living with vascular disease means looking after your blood vessels every day. It does not have to take over your life. Follow your treatment plan, attend follow-up appointments, and keep an eye on your legs and feet. Many people manage their symptoms well and continue to live active, full lives.

Lifestyle tips

• Stop smoking and avoid secondhand smoke.
• Manage blood pressure and cholesterol — take medicines as prescribed.
• Control diabetes if you have it.
• Stay physically active with activities you enjoy — walking, swimming, cycling.
• Aim for at least 30 minutes of moderate activity on most days, as you are able.
• Keep a healthy weight.
• Limit alcohol and eat a heart-healthy diet.

Diet and exercise

Focus on a diet low in salt, saturated fats, and added sugar. Eat plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats like olive oil and nuts. Exercise such as brisk walking, swimming, or cycling improves circulation, but start slowly and check with your doctor if you are unsure. If walking hurts your legs, use the 'walk a little, rest a little' approach — over time your distance may improve.

Mental health and emotional wellbeing

Living with a chronic condition can cause worry, stress, or low mood. It is normal to feel anxious when you think about blood vessels and circulation. Talk to your healthcare team about these feelings. You are not alone — many people with vascular conditions cope well with support from family, friends, and professionals.

Prevention

You cannot change some factors like age and family history, but you can significantly lower your risk. The same lifestyle habits that treat vascular disease also prevent it: not smoking, staying active, eating well, keeping a healthy weight, and managing high blood pressure, cholesterol, and diabetes. Regular health checks can catch problems early.

Screening programmes

If you have strong risk factors (such as diabetes, smoking, high blood pressure, or a family history), your doctor may recommend regular checks like an ankle-brachial index test or an ultrasound scan of your aorta. There is no national screening for everyone, but you can ask your doctor what is right for you.

Complications

If left untreated

• Complete blockage of an artery in a leg — causing severe pain, tissue damage, and potentially amputation
• Blood clot traveling to the lungs (pulmonary embolism) — a life-threatening emergency
• Stroke, if a clot blocks blood flow to the brain
• Heart attack, if a coronary artery becomes blocked
• An expanding or ruptured aneurysm — which can cause severe internal bleeding and be fatal
• Chronic wounds and ulcers that may become infected

Long-term outlook

With early diagnosis and proper management, most people with vascular disease can live well for many years. Treatment has improved a great deal, and many people see their symptoms ease and their circulation improve. The most important thing is to take action — talk to your doctor, follow your treatment plan, and make the healthy changes that you can. Exactly that is possible.
