Peripheral Artery Disease and Leg Circulation in Brampton

Most people know that narrowed arteries can lead to heart attacks and strokes. Fewer realise that the same process can affect the arteries that supply the legs. When those arteries narrow, the result is called peripheral artery disease, or PAD. It is a common condition, particularly among older adults, people with diabetes and people who smoke, yet it often goes unrecognised for years.

PAD matters for two reasons. First, it can cause leg pain, limit how far you can walk, and in more advanced cases lead to wounds that heal poorly. Second, and just as importantly, PAD is a sign that the arteries elsewhere in the body, including those supplying the heart and brain, may also be affected. People with PAD have a higher risk of heart attack and stroke.

This post explains what PAD is, what symptoms to look for, who is at higher risk and how it is commonly managed. If you have questions about your circulation or medications, the pharmacists at Pharmasave BramCentre, 14 - 7910 Hurontario Street in Brampton are glad to help.

What happens in peripheral artery disease

Arteries carry oxygen-rich blood from the heart to the rest of the body. Over time, fatty deposits called plaque can build up inside artery walls, a process known as atherosclerosis. As plaque grows, the artery narrows and less blood can flow through it.

In PAD, this narrowing affects arteries outside the heart and brain, most often in the legs. When you are resting, the reduced flow may still be enough. But when you walk and your leg muscles need more oxygen, the narrowed arteries cannot keep up. That mismatch is what causes the classic symptom of PAD.

The classic symptom: pain when walking

The best-known symptom of PAD is called intermittent claudication. It usually feels like cramping, aching, tiredness or heaviness in the calf, thigh or buttock that:

• Comes on with walking or climbing stairs
• Occurs after roughly the same distance or effort each time
• Eases within a few minutes of resting

Many people assume this is just aging, arthritis or being out of shape, and they quietly walk less to avoid it. That is understandable, but it is worth mentioning to your doctor, because it may be a sign of PAD and an opportunity to protect your heart as well as your legs.

Other signs worth noticing

PAD does not always cause classic claudication. Some people, especially those with diabetes or nerve damage, may have few symptoms. Other possible signs include:

• Cold feet or lower legs, especially compared with the other side
• Shiny skin, hair loss or slow nail growth on the legs and feet
• Weak or absent pulses in the feet
• Sores or wounds on the toes, feet or legs that heal slowly or not at all
• Changes in skin colour of the legs or feet
• Pain in the feet or toes at rest, especially at night, that improves when the legs hang down

Seek urgent medical care if a leg or foot suddenly becomes cold, pale, painful, numb or weak, or if you develop a wound with spreading redness, warmth, swelling or discharge.

Who is at higher risk

The risk factors for PAD overlap closely with those for heart disease and stroke:

• Smoking, one of the strongest risk factors
• Diabetes
• High blood pressure
• High cholesterol
• Older age
• Chronic kidney disease
• A personal or family history of heart disease or stroke

Diabetes deserves special mention. People with diabetes are more likely to develop PAD, and nerve damage from diabetes can mask symptoms, meaning foot wounds may not be noticed until they become serious. In Brampton, where diabetes affects many families, this connection is particularly important.

How PAD is diagnosed

If your doctor suspects PAD, they may check the pulses in your feet and look at the skin of your legs. A common, painless test is the ankle-brachial index (ABI), which compares blood pressure readings at the ankle and the arm. A lower pressure at the ankle suggests narrowing in the leg arteries. Further imaging may be arranged if needed.

If you have symptoms or several risk factors, ask your doctor or nurse practitioner whether an assessment for PAD is appropriate.

Treatment protects your heart as well as your legs

PAD treatment usually has two goals: relieving leg symptoms and reducing the risk of heart attack and stroke. Common approaches include:

• Stopping smoking, which is one of the most effective steps
• Structured walking programs, which can improve how far people can walk before pain begins
• Blood pressure control
• Cholesterol-lowering medications, often statins
• Antiplatelet medications or other blood thinners in some people
• Blood sugar management for people with diabetes
• Procedures to open or bypass narrowed arteries, in selected cases

Your healthcare team will tailor the plan to you. Taking prescribed medications consistently is a big part of that plan, even if they do not change how your legs feel day to day, because they are working to protect your heart and brain.

Walking through the discomfort, safely

It may seem counterintuitive, but walking is one of the most effective treatments for claudication. Supervised exercise programs often encourage people to walk until moderate discomfort develops, rest until it eases, and then continue. Over weeks, many people find they can walk further before pain starts.

Before starting such a program, check with your doctor. If you have heart disease, foot wounds or other conditions, you may need a modified approach. In Brampton’s colder months, indoor walking at a shopping centre or community centre can help keep the routine going.

Foot care matters

Because PAD reduces blood flow to the feet, even small injuries can heal slowly. Daily foot care is an important habit:

1. Check your feet every day for cuts, blisters, redness or colour changes. Use a mirror or ask a family member if you cannot see the soles.
2. Wash and dry your feet carefully, including between the toes.
3. Moisturise dry skin, but not between the toes.
4. Wear well-fitting shoes and clean socks; avoid walking barefoot.
5. Trim nails carefully, or seek help from a foot care professional.
6. Avoid using heating pads or hot water bottles on your feet, as reduced sensation can lead to burns.

If you have diabetes, the pharmacy’s diabetes support page outlines how the team can help with monitoring and supplies.

PAD or something else? Telling leg pains apart

Leg pain has many possible causes, and it is not always easy to tell them apart on your own. Arthritis in the hip or knee usually hurts in the joint itself and may be worse with the first steps after sitting. Pain from a pinched nerve in the lower back can travel down the leg and may ease when you bend forward or sit, rather than simply when you stop walking. Muscle cramps at night are common and often unrelated to circulation. Swelling and aching that worsen through the day may point to vein problems rather than artery problems.

Claudication from PAD has a recognisable pattern: it is triggered by walking, it tends to occur after a similar distance each time, and it settles with a few minutes of standing still. Keeping a simple diary can help your doctor sort out the cause. Note how far you walked before the pain began, where exactly you felt it, what it felt like and how long it took to ease. Also note whether one leg is affected more than the other.

Bringing that information to your appointment, along with your list of medications and risk factors, gives your provider a clearer starting point than “my legs hurt when I walk.”

Medications and support from your pharmacy

PAD often involves several medications for blood pressure, cholesterol, blood clots and diabetes. Your pharmacist can help you understand what each is for, check for interactions, and support you in staying consistent.

At Pharmasave BramCentre, a medication review is a good way to go through your full list. If you are trying to quit smoking, ask about smoking cessation support through the pharmacy. Keeping supply steady through the prescription refill service helps make sure protective medications are never interrupted.

Be cautious with over-the-counter products, especially pain relievers and supplements, if you take blood thinners or antiplatelet medications. Ask the pharmacist before starting anything new.

Footwear and foot products deserve the same caution. Corn and callus removers, medicated pads and some wart treatments work by softening or peeling the skin, and on a foot with reduced circulation that small injury can be slow to heal. If you have PAD or diabetes, ask the pharmacist before using any of these, and consider having a foot care professional deal with corns, calluses and thick nails instead. When buying new shoes, shop later in the day when feet tend to be slightly larger, and break them in gradually while checking for rubbed or red areas. A useful question to bring to the counter is simply: “I have poor circulation in my legs. Is this product safe for my feet?”
