Peripheral Artery Disease (PAD) is a circulation problem where narrowed arteries reduce blood flow to your limbs. PAD affects millions of Americans, more than those currently living with cancer. Yet even though it’s so common, this condition often goes unnoticed until it’s caused huge problems.
What Exactly Is Peripheral Artery Disease?
In simple terms, Peripheral Artery Disease (PAD) is a circulatory problem where narrowed arteries reduce blood flow to your limbs, most commonly the legs. It’s caused by atherosclerosis, the same process that leads to coronary artery disease. Fatty deposits build up in your artery walls, restricting blood flow and depriving your muscles and tissues of the oxygen they desperately need.
Think of your arteries like water pipes. When sediment and mineral deposits build up inside, water flow becomes restricted. Similarly, when plaque builds up in your arteries, blood flow becomes limited, depriving your tissues of the oxygen they need.
Why Should You Care About PAD?
The real shocker is that Peripheral Artery Disease (PAD) doesn’t just affect your legs. It’s a sign that atherosclerosis might be happening throughout your body, including arteries that supply blood to your heart and brain. This means people with PAD have a significantly higher risk of heart attack and stroke.
Also, severe PAD can lead to tissue death, chronic wounds, and in extreme cases, amputation. Now, let’s talk about the 10 warning signs you can look out for.
1. Leg Pain During Activity
This is the classic Peripheral Artery Disease symptom that affects many patients. You’re walking along just fine, then suddenly your calf, thigh, or buttocks start cramping or aching. The discomfort builds until you stop walking, then it fades away as you relax. This happens because your muscles need more oxygen during exercise, but your narrowed arteries can’t deliver enough blood to meet the demand.
2. Numbness or Weakness in the Legs
Does your leg sometimes feel like it’s falling asleep for no reason? PAD can cause decreased sensation, weakness, or a pins-and-needles feeling in your lower extremities. This numbness occurs because your nerves aren’t getting the blood supply they need to function properly.
3. Shiny, Smooth Skin on Your Legs
Take a look at your legs. Is the skin unusually smooth, shiny, or tight? When arteries are blocked, your skin doesn’t receive enough nutrients and oxygen, causing changes in its appearance and texture. It’s your body’s external signal that something’s going wrong internally.
4. Hair Loss on Your Feet and Legs
Have you noticed that the hair on your lower legs or feet has mysteriously disappeared? Hair follicles are particularly sensitive to reduced blood flow. When they don’t get enough nutrients, they can’t support hair growth. Patchy or complete hair loss on your legs, especially when combined with other symptoms, could be a telltale sign of Peripheral Artery Disease.

5. Slow-Healing Wounds
Have you ever cut or scraped your foot and it just won’t heal? Reduced blood flow seriously slows down your body’s natural healing process. Even minor injuries can become stubborn wounds when your tissues aren’t receiving enough oxygen and nutrients to repair themselves.
6. Skin Discoloration
If your legs or feet look pale, bluish, or reddish even when elevated, PAD could be the culprit. This discoloration happens because not enough blood is reaching your extremities, causing visible changes in skin color that may worsen with position changes.
7. Cold Feet or Legs (Especially One Colder Than the Other)
Have you ever experienced your feet or legs feeling suddenly cold, particularly compared to the rest of your body? Or is one foot consistently colder than the other? Reduced blood flow means less warmth reaching your extremities. This temperature difference can be particularly noticeable when comparing one side to the other.
8. Weak or Absent Pulses in Your Feet
While this isn’t something you might notice yourself, it’s a key sign healthcare providers look for. Weakened or absent pulses in the feet indicate that blood isn’t flowing normally through those arteries, a classic indicator of PAD that your doctor can easily check.
9. Changes in Toenail Growth
PAD can cause your toenails to grow more slowly or become thickened and distorted. Like hair follicles, your nails need good blood supply to develop normally. When that supply is compromised, your nail health suffers.
10. Erectile Dysfunction in Men
This might seem unrelated, but PAD can affect arteries throughout the body. In men, reduced blood flow to the pelvic area can cause erectile dysfunction, often before leg symptoms become obvious. It’s part of a condition called Leriche syndrome, where PAD affects the arteries in the lower abdomen and pelvis.
Who’s at Risk for PAD?
You’re more likely to develop PAD if you:
- Smoke (this is the biggest controllable risk factor)
- Have diabetes
- Have high blood pressure
- Have high cholesterol
- Are over 60
- Have a family history of PAD or other cardiovascular diseases
- Are overweight or obese
- Live a sedentary lifestyle
What Should You Do if You Suspect PAD?
If you’re experiencing any of these symptoms, especially leg pain with activity that goes away with rest, it’s time to talk to your doctor. Diagnosis typically starts with a simple test called an ankle-brachial index (ABI), which compares the blood pressure in your ankle to the blood pressure in your arm.
PAD is treatable, especially when caught early. Treatment options include:
- Lifestyle changes (quitting smoking, regular exercise, and healthy eating)
- Medications to lower cholesterol, control blood pressure, and prevent blood clots
- Supervised exercise programs
- Procedures to restore blood flow in severe cases
Please Don’t Wait Until It’s Too Late
The tricky thing about PAD is that symptoms often come and go, making it easy to dismiss them. You might feel that cramping during your walk, but once you rest and the pain subsides, you forget about it until the next time. The issue is PAD is a progressive disease that typically worsens without treatment. Remember, it’s not just about your legs. PAD indicates a higher risk for heart attack and stroke, so addressing it promptly protects your entire cardiovascular system.
