What is Peripheral Artery Disease (PAD)?
Peripheral Artery Disease (PAD) is a circulatory condition in which narrowed arteries reduce blood flow to the limbs, most commonly the legs. It is caused by atherosclerosis—plaque buildup in the arteries—and can lead to pain, mobility issues, and in severe cases, limb loss. PAD is also a warning sign of widespread arterial disease, which may affect the heart and brain, increasing the risk of heart attacks and strokes.
Symptoms of PAD
PAD often develops gradually and may not show symptoms until the arteries are significantly blocked. Common symptoms include:
- Leg Pain While Walking (Claudication): Cramping or aching in the hips, thighs, or calves during activity, which improves with rest.
- Numbness or Weakness: Especially in the legs or feet.
- Coldness in the Lower Leg or Foot: Especially compared to the other leg.
- Sores on Toes, Feet, or Legs: That heal slowly or not at all.
- Shiny Skin and Hair Loss: On the legs or feet.
- Weak or Absent Pulse in Legs or Feet: Detected during a physical exam.
