Peripheral Artery Disease (PAD)
Narrowing of the arteries in the legs from plaque build-up, reducing blood flow. It commonly causes leg pain when walking and raises the risk of heart attack and stroke.
Causes & risk factors
- Atherosclerosis (fatty plaque in arteries)
- Smoking
- Diabetes
- High blood pressure and cholesterol
- Ageing and lack of exercise
Common symptoms
Tests & diagnosis
Treatment & management
- Stop smoking — the single most important step
- Supervised walking exercise programmes
- Medicines to control cholesterol, BP and prevent clots
- Careful foot care, especially in diabetes
- Angioplasty, stenting or bypass surgery for severe cases
When to see a doctor urgently
- Seek urgent care for a suddenly cold, painful, pale leg (possible blockage)
- See a doctor for leg pain on walking that eases with rest
- Get non-healing foot sores checked promptly, especially with diabetes

Frequently asked questions
Why does PAD matter beyond the legs?
The same plaque affects heart and brain arteries, so PAD signals a higher risk of heart attack and stroke.
Can walking really help?
Yes — regular supervised walking often improves how far you can walk before pain starts.
