Peripheral Arterial Disease

Peripheral arterial disease is narrowing of arteries that can reduce blood flow to the legs and feet.

Fatty material can build up in artery walls, making it harder for blood to reach working muscles and skin. The condition may develop gradually, and some people have no noticeable discomfort until circulation is more limited.

Leg pain when walking is a very common presentation of peripheral arterial disease. It may feel like a cramp, ache or tightness in the calf, thigh or buttock and often eases with rest.

Cold hands and feet and muscle cramps are also common presentations. Other signs can include a foot that feels cooler than the other, slow-healing sores, colour change, or pain in the foot while resting. Seek urgent care for a suddenly cold, pale, painful or weak limb.

The usual process is atherosclerosis, in which deposits within the artery wall narrow the channel for blood flow. Tobacco exposure, raised cholesterol and diabetes can contribute to this process. Less commonly, a clot or inflammation can affect limb circulation.

Risk is higher with smoking or nicotine use, diabetes, high cholesterol, high blood pressure, kidney disease, increasing age, and a close family history of vascular disease. Several factors can occur together, so a review of the whole cardiovascular picture is useful.

A clinician will ask where discomfort occurs, what brings it on, and whether wounds are healing. They examine pulses, skin temperature and the feet. An ankle-brachial pressure comparison may be used to compare circulation in the ankle and arm; ultrasound or other imaging can help map narrowed areas when needed.

Care aims to improve walking comfort, protect the skin and lower the chance of vascular problems elsewhere. It may include a supported walking plan, stopping tobacco, medicines that address cholesterol or clotting risk, and management of blood pressure or diabetes. Procedures to improve blood flow are considered when symptoms severely limit daily life or tissue is threatened.

Check feet and lower legs regularly for cuts, blisters or colour change, especially if sensation is reduced. Wear well-fitting footwear, avoid treating corns or calluses yourself, and arrange prompt review for a wound that is not improving. Keep a note of how far you can walk before symptoms start to help guide follow-up.

Very poor circulation can lead to persistent rest pain, ulcers or tissue damage. Sudden severe limb pain, new weakness, numbness, marked coldness, or a blue or pale foot needs emergency assessment. Peripheral arterial disease can also signal artery disease in other parts of the body, which is why ongoing prevention matters.

Stopping smoking, taking prescribed medicines consistently, choosing regular movement within your limits, and managing diabetes, cholesterol and blood pressure can support artery health. A clinician can tailor goals around your symptoms and other conditions.

A primary-care clinician can start assessment and coordinate risk-factor care. Referral to a vascular specialist may be appropriate for uncertain diagnosis, limiting symptoms, non-healing wounds, or signs of threatened circulation.
