Peripheral artery disease (PAD) is a circulation problem where the arteries that carry blood to your legs become narrowed or blocked. Most of the time, this happens because of atherosclerosis, which is plaque buildup inside the artery. Risk factors include smoking, diabetes, high blood pressure, high cholesterol, kidney disease, older age, and a family history of vascular disease.
No one can promise to prevent PAD. But there are practical steps that help slow its progression and protect your legs. PAD is common and often underdiagnosed, because symptoms can be mild or mistaken for “just aging.” This guide covers causes, risk factors, warning symptoms (including emergencies), and what you can do day to day.
What causes peripheral artery disease?
PAD is narrowing of the arteries, most commonly in the legs. The most common cause is atherosclerosis. Think of plaque as sticky cholesterol gunk that makes the opening of the blood vessel smaller.
When less blood gets to your leg muscles, walking can start to hurt, and wounds can heal more slowly. PAD is also a warning sign that similar plaque may be present in your heart and brain arteries too. That is why PAD care is not only about your legs. It is also about reducing heart attack and stroke risk.
Which risk factors raise your chances of PAD?
Common PAD risk factors include:
- Smoking, current or past
- Diabetes
- High blood pressure
- High cholesterol
- Kidney disease
- Older age
- Family history of vascular disease
Having a risk factor does not mean you will develop PAD, and PAD can be present without clear warning signs. Treatment for the disease often includes smoking cessation support, diabetes and blood pressure control, and cholesterol lowering therapy, so these risk factors are worth discussing with your clinician.
What are the most common PAD symptoms?
The classic PAD symptom is claudication, which means muscle pain or tightness with walking that improves with rest. It is not the same as joint pain. It feels more like the muscle is running out of oxygen.
Because PAD can show up as hip, thigh, or calf discomfort, people often blame joints or sciatica. Other common symptoms include:
- Calf, thigh, or buttock pain with walking that stops with rest
- Leg fatigue or heaviness when walking
- Cold feet, or one foot that feels colder than the other
- Numbness or weakness in the legs
- Slow healing sores on toes, feet, or ankles
- Shiny skin, hair loss on the legs, or thick toenails, which can be signs of reduced circulation
Which PAD symptoms are an emergency?
Some symptoms need urgent care right away:
- Sudden severe leg pain
- A leg or foot that becomes cold, pale, or blue
- New inability to move your toes or foot
- Sudden numbness with worsening pain
These can be signs of acute limb ischemia, which means a sudden loss of blood flow. It is time sensitive, so do not wait to see if it gets better. Seek urgent care immediately.
What can you do to slow PAD progression and protect your legs?
Small daily actions make a big difference with PAD, because PAD is strongly tied to overall artery health. Practical steps that help include:
- Walk regularly, as guided by your clinician. Walking trains your muscles to use oxygen more efficiently.
- Take prescribed medications consistently, especially cholesterol and antiplatelet therapy when indicated.
- Stop smoking, since smoking is one of the strongest drivers of PAD progression.
- Check your feet daily, especially if you have diabetes. Look for blisters, cuts, redness, or color change, and do not ignore a wound that is not improving.
- Call early for new symptoms, like new rest pain, toe discoloration, or a sore that is not healing.
Research supports structured exercise as a powerful treatment for improving walking ability in claudication. Some patients with PAD also benefit from specific antithrombotic strategies to lower limb and cardiovascular events, depending on their risk profile and clinical situation. Ask your clinician whether this applies to you, and do not start or stop any medication on your own.
Walking based exercise therapy is a common part of treatment, especially supervised exercise therapy for claudication. Some studies also show added improvement when exercise is paired with revascularization in selected cases.
PAD treatment usually has two goals: to help you walk and feel better, and to lower the risk of heart attack, stroke, and limb complications. Minimally invasive or surgical procedures may be discussed for select patients with lifestyle limiting symptoms or more severe disease.
When should you see a vascular specialist?
PAD is treatable, but it is not something to brush off as “just getting older.” If walking is painful, your feet stay cold, or you have a sore that will not heal, it is worth getting checked.
Evaluation usually starts with your symptoms, a pulse exam, and simple circulation tests. A key first test is the ankle brachial index (ABI), which compares blood pressure at the ankle to blood pressure in the arm. At VidaVascular, a vascular and interventional care practice, you can learn more about our peripheral artery disease evaluation and treatment options, or browse the conditions we evaluate.
Depending on your situation, testing may also include a toe brachial index, which is helpful when the ABI is less reliable, such as with diabetes or stiff arteries. A duplex ultrasound can look at blood flow and narrowing, and CTA or MRA imaging may be used in some cases when more detail is needed for planning care.
