questions to ask before artery

Overview

Peripheral artery disease (PAD) is a condition where the arteries that carry blood to your legs and feet become narrowed or blocked. This often happens because of fatty deposits (plaque) building up inside the artery walls. When the arteries narrow, less blood can flow to your legs, especially during activity.

Yes, peripheral artery disease is fairly common, particularly in older adults. It affects about 1 in 20 people over 50, and the risk increases with age. Many people may not know they have it because symptoms can be mild or mistaken for other problems.

PAD most often affects people over 50. It is more common in those who smoke, have diabetes, high blood pressure, high cholesterol, or are overweight. Men and women are both at risk, though men may develop it at a slightly younger age.

Symptoms

Common symptoms

• Painful cramping in the hip, thigh, or calf muscles after walking or climbing stairs (called claudication)
• Numbness or weakness in the legs
• Coldness in the lower leg or foot, especially compared to the other side
• Sores on the toes, feet, or legs that heal slowly or not at all
• Change in the color of the legs (pale, bluish, or reddish)
• Hair loss or slower hair growth on the legs and feet
• Shiny, tight skin on the legs

Symptoms in children

• Peripheral artery disease is extremely rare in children. If it occurs, it is usually due to a genetic condition or severe illness. Symptoms may include leg pain with exercise, poor growth of the affected limb, or a difference in blood pressure between arms and legs.

Symptoms in older adults

• In older adults, symptoms may be less clear or mistaken for normal aging. They might feel tired legs, trouble walking as far as before, or notice that foot sores heal slowly. Some older adults with PAD have no symptoms at all.

Causes

Main causes

• Atherosclerosis: the buildup of fatty plaque inside artery walls, which narrows or blocks the arteries over time.
• Blood clots that form in narrowed arteries can worsen the blockage.
• In rare cases, inflammation of blood vessels (vasculitis) or injury to the arteries can cause PAD.

Risk factors

• Smoking or using tobacco (the strongest risk factor)
• Diabetes
• High blood pressure
• High cholesterol
• Obesity
• Being over 50 years old
• Having a family history of heart disease, stroke, or PAD
• Physical inactivity

When to see a doctor

See a doctor urgently if:

• If you have sudden, severe leg pain that does not go away with rest
• If your leg turns pale, cold, or numb
• If a foot or leg sore becomes infected, deep, or has a bad smell
• If you have chest pain, shortness of breath, or other signs of a heart attack or stroke along with leg symptoms

Book a routine appointment if:

• If you have leg cramps or pain when walking that gets better with rest
• If you notice that sores on your feet or legs are slow to heal
• If you have risk factors like diabetes, smoking, or high blood pressure and are over 50

Diagnosis

Your doctor will start by asking about your symptoms, medical history, and lifestyle. They will check the pulses in your legs and feet, and may compare blood pressure in your arms and ankles. The main test is a simple, painless ultrasound called an ankle-brachial index (ABI).

Tests that may be done

• Ankle-brachial index (ABI): compares blood pressure in your ankle with blood pressure in your arm
• Doppler ultrasound: uses sound waves to see blood flow in your arteries
• Angiogram: a dye X-ray that shows blockages (less common for initial diagnosis)
• Blood tests: to check for diabetes, high cholesterol, or other contributing conditions

What to expect at your appointment

Diagnosis is usually straightforward and does not require a hospital visit. The ABI test takes about 10-15 minutes and is painless. You may be asked to walk for a short time on a treadmill before the test to see how your blood pressure changes. Your doctor will explain the results and what they mean for your health.

Treatment

Treatment for peripheral artery disease focuses on managing symptoms, improving blood flow, and reducing your risk of heart attack and stroke. It often starts with lifestyle changes and may include medications or procedures if needed. Before any artery procedure (like angioplasty or bypass), your doctor will explain what will happen and answer any questions you have.

Self-care at home

• Walk regularly: a supervised walking program can improve symptoms over time
• Stop smoking: it is the single most important step you can take
• Eat a heart-healthy diet: low in saturated fats, salt, and sugar
• Keep diabetes and blood pressure under control with your doctor help
• Check your feet daily for cuts, blisters, or sores that could get infected

Medical treatments

Your doctor may recommend medicines to prevent blood clots (like aspirin), lower cholesterol (statins), control blood pressure, or improve blood flow. It is important to take these exactly as prescribed. Never stop or change your medicines without talking to your doctor. If blockages are severe, a procedure such as angioplasty (opening the artery with a tiny balloon) or bypass surgery may be considered. Your doctor will discuss the risks and benefits of any procedure before you agree to it.

When is surgery considered?

Surgery is usually reserved for severe PAD that does not improve with lifestyle changes and medicines, or when there is a risk of losing the leg. Bypass surgery creates a new route for blood to flow around the blocked artery. Your doctor will explain if this is an option for you and what the recovery involves.

Living with this condition

Living with PAD means taking care of your legs and your overall heart health. Walking regularly is one of the best things you can do, even if it hurts at first. Over time, your body builds new blood vessels to help. Keep your feet clean, dry, and check them every day for any changes. Wear comfortable, well-fitting shoes and never go barefoot.

Lifestyle tips

• Walk for at least 30 minutes most days, even if you need to stop and rest often
• Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins
• Maintain a healthy weight to take pressure off your legs
• Quit smoking – your doctor or local health service can help
• Manage stress through relaxation techniques or talking to a counsellor

Diet and exercise

A heart-healthy diet can help slow the progression of PAD. Choose foods low in saturated fat, salt, and added sugars. Aim for plenty of fibre from fruits, vegetables, and whole grains. Exercise, especially walking, is a key part of treatment. A structured walking program (supervised by a physical therapist or nurse) can greatly improve your symptoms and quality of life.

Mental health and emotional wellbeing

Living with a chronic condition like PAD can sometimes cause worry, frustration, or even depression. You may feel limited in activities you once enjoyed. It is important to talk to your doctor about how you are feeling. They can connect you with resources or support groups. Your feelings are valid, and help is available.

Prevention

You can reduce your risk of developing PAD by adopting a healthy lifestyle. Quitting smoking, controlling diabetes and blood pressure, eating well, and exercising regularly all help. Once you have PAD, these steps can prevent it from getting worse and reduce your risk of heart attack or stroke.

Vaccines

No vaccine prevents PAD, but staying up to date on vaccines like flu and pneumonia can reduce complications if you have heart disease.

Screening programmes

If you have risk factors (smoking, diabetes, age over 50), your doctor may recommend a simple ankle-brachial index test to check for PAD even if you have no symptoms. This is not routine for everyone, so ask your doctor if screening is right for you.

Complications

If left untreated

• Non-healing sores and infections on the feet or legs that may spread
• Gangrene (tissue death) that may require amputation
• Critical limb ischemia (severe lack of blood flow that causes constant pain)
• Increased risk of heart attack and stroke due to the same artery-clogging process

Long-term outlook

With early detection and proper management, most people with PAD can control their symptoms and avoid serious complications. Many people live full, active lives by making healthy choices and following their treatment plan. Your outlook depends on your overall health, but there is good reason to be hopeful. Taking small steps every day can make a big difference.
