Peripheral Artery Disease: Symptoms, Causes and When to Seek Medical Care

Leg pain is often considered a normal part of ageing or physical activity. However, recurring leg pain while walking, cold feet, or slow-healing wounds can sometimes indicate an underlying blood circulation problem. One such condition is Peripheral Artery Disease (PAD).

Peripheral Artery Disease occurs when arteries that carry blood to the legs and other parts of the body become narrowed or blocked. Early medical evaluation can help identify the condition and guide appropriate treatment.

What Is Peripheral Artery Disease?

Peripheral Artery Disease is a circulation disorder in which narrowed arteries reduce blood flow to the limbs, most commonly the legs.

Atherosclerosis, or the buildup of fatty deposits inside the arteries, is a common cause. PAD can also be associated with factors such as diabetes, smoking, high blood pressure, high cholesterol, and increasing age.

Because PAD is related to blood vessel health, it can also indicate an increased risk of other cardiovascular problems.

Common Symptoms of Peripheral Artery Disease

Some people with PAD may not notice symptoms in the early stages. When symptoms occur, they can include:

• Leg pain or cramping while walking
• Pain that improves after resting
• Numbness or weakness in the legs
• Coldness in one foot or leg
• Changes in the colour of the skin
• Reduced hair growth on the legs or feet
• Slow-healing cuts or sores on the feet
• Weak or difficult-to-feel pulses in the legs

A recurring pattern of leg discomfort during walking should not always be considered ordinary muscle fatigue.

What Causes Peripheral Artery Disease?

PAD commonly develops because of plaque buildup inside the arteries. Several factors can increase the risk, including:

Diabetes

High blood sugar over a long period can affect blood vessels and increase the risk of circulation problems.

Smoking

Smoking can damage blood vessels and increase the risk of artery disease.

High Blood Pressure

Uncontrolled blood pressure can contribute to damage of the arterial walls.

High Cholesterol

High levels of certain blood lipids can contribute to plaque formation inside arteries.

Age and Family History

The risk of peripheral artery disease generally increases with age and may also be influenced by family history of cardiovascular disease.

How Is Peripheral Artery Disease Diagnosed?

A doctor may begin with a medical history and physical examination. Depending on the symptoms and clinical findings, additional tests may be recommended.

These can include:

• Ankle-Brachial Index (ABI)
• Doppler ultrasound
• Blood tests
• CT angiography or other vascular imaging when required

The appropriate investigation depends on the patient’s symptoms and overall health.

Why Should PAD Symptoms Not Be Ignored?

Reduced blood flow to the legs can become more serious if the condition progresses. Severe circulation problems may lead to persistent pain, non-healing wounds, or other complications.

People with diabetes or existing cardiovascular risk factors should be particularly attentive to changes in their feet and legs.

Early consultation allows a doctor to assess the symptoms and determine whether further cardiovascular or vascular evaluation is required.

How Can You Reduce the Risk?

Some lifestyle measures can help support better cardiovascular health:

• Avoid smoking and tobacco
• Maintain healthy blood pressure and cholesterol levels
• Keep diabetes under appropriate control
• Stay physically active as advised by your doctor
• Follow a balanced diet
• Maintain a healthy body weight
• Attend regular health check-ups when recommended

People who already have cardiovascular risk factors should discuss an appropriate prevention and treatment plan with their healthcare provider.

Frequently Asked Questions

What is Peripheral Artery Disease?

Peripheral Artery Disease is a condition in which narrowed or blocked arteries reduce blood flow, commonly to the legs.

Is leg pain while walking always caused by PAD?

No. Leg pain can have several causes. However, recurring pain that develops during walking and improves with rest should be evaluated by a doctor.

Who is at higher risk of Peripheral Artery Disease?

People with diabetes, smoking history, high blood pressure, high cholesterol, increasing age, or cardiovascular risk factors may have a higher risk.

Can Peripheral Artery Disease be treated?

Treatment depends on the severity and cause. Doctors may recommend lifestyle changes, medicines, supervised exercise, or procedures when clinically appropriate.
