Peripheral artery disease (PAD) is a common condition that affects the blood flow to your legs and feet. It happens when the arteries that carry blood from your heart to your limbs become narrow or blocked.
This makes it hard for enough blood to reach your legs and feet, especially when you are active. Without enough blood flow, your muscles don’t get the oxygen they need, which can cause pain and other problems.
The most common symptom of PAD is called claudication. This is a type of pain or cramping in your legs or arms that happens when you exercise and goes away when you rest. Most people feel this discomfort in their calves, but it can also happen in the thighs or buttocks. For some people, the pain can be so bad that it makes it hard to walk or do other physical activities.
Other symptoms of PAD include numbness or weakness in your legs, a feeling of coldness in your lower leg or foot compared to the other side, and sores on your toes, feet, or legs that don’t heal properly.
You might also notice that the color of your legs changes—they may look pale or even bluish. Hair loss or very slow hair growth on your feet and legs can also be a sign. In very severe cases, PAD can lead to tissue death, known as gangrene, which may require amputation if not treated quickly.
Certain people are more likely to develop PAD than others. The risk increases as you get older, and it’s especially high if you smoke, have diabetes, high blood pressure, or high cholesterol. A family history of vascular diseases also raises your chances.
These conditions contribute to a buildup of fatty deposits in your arteries, a condition called atherosclerosis. When this happens, the arteries become narrow, and less blood can flow through them.
To diagnose PAD, doctors usually start with a physical exam and a simple test called the ankle-brachial index (ABI). This test compares the blood pressure in your ankle with the blood pressure in your arm.
If the blood pressure in your ankle is much lower than in your arm, it’s a sign that blood is not flowing well to your legs. Other tests, like ultrasound, angiography, or magnetic resonance angiography (MRA), can help doctors see how well blood is moving through your arteries and spot any blockages.
Treating PAD focuses on relieving symptoms and preventing further complications like heart attacks or strokes. One of the most important steps is making lifestyle changes. Quitting smoking is crucial because smoking damages blood vessels and worsens artery blockages.
Regular exercise, particularly walking, helps improve blood flow to your legs and reduces pain over time. Eating a healthy diet that’s low in saturated fats and trans fats also helps keep your arteries clear.
Medications can also play a role in managing PAD. Doctors may prescribe blood thinners to prevent clots, medications to lower blood pressure, and statins to reduce cholesterol. Lowering cholesterol levels can help prevent the buildup of fatty deposits in the arteries and reduce the risk of heart attacks and strokes. Some people may also take medication to help relieve pain during exercise.
In more serious cases, medical procedures may be needed to restore blood flow. One common procedure is called angioplasty. During this procedure, a thin tube with a balloon at the tip is inserted into the blocked artery.
When the balloon is inflated, it pushes the fatty deposits against the artery walls, opening up the pathway for blood. Sometimes, a small metal tube called a stent is left in place to keep the artery open.
If angioplasty isn’t an option, bypass surgery may be recommended. This involves creating a new path for blood to flow around the blocked artery, similar to how a road detour works. This allows blood to reach your legs and feet more easily.
Supervised exercise programs can also help people with PAD. These programs are designed to gradually increase your walking distance and improve your leg strength. They are often part of cardiac rehabilitation programs that help you safely increase your activity level under medical supervision.
In summary, PAD is a serious condition that affects blood flow to the legs and feet, causing pain, cramping, and other symptoms. The good news is that it can be managed effectively with lifestyle changes, medications, and sometimes medical procedures.
Recognizing the symptoms early and getting proper treatment can improve your quality of life and reduce the risk of serious complications like heart attacks or strokes. Taking care of your health by exercising, eating well, and avoiding smoking can make a big difference in managing PAD and keeping your arteries healthy.
