Peripheral artery disease

Definition

Peripheral artery disease (PAD) is a condition characterized by narrowed arteries, which reduce blood flow to the limbs. It often leads to pain and mobility issues due to decreased oxygen supply.

5 Must Know Facts For Your Next Test

1. PAD is commonly caused by atherosclerosis, where fatty deposits build up in the artery walls.
2. Symptoms of PAD include leg pain when walking (claudication), numbness, and weakness in the legs.
3. Nutrition plays a crucial role in managing PAD; diets high in fruits, vegetables, whole grains, and lean proteins can help reduce symptoms.
4. Patients with PAD are at higher risk for cardiovascular events like heart attacks and strokes.
5. Smoking cessation is critical for individuals with PAD as smoking exacerbates artery narrowing.
