What causes PAD?

A clinician showing a patient a model of an artery narrowed by plaque

A leg symptom that keeps coming back raises one obvious question: what is behind it? For peripheral artery disease, the cause is the first thing worth understanding.

The main cause, stated plainly

On the cause of PAD, www.nhlbi.nih.gov states that "Atherosclerosis is the main cause of PAD", which puts the cause in the arteries. Ask about the arteries first.

Where to read further

For the wider picture, my.clevelandclinic.org has a guide to vascular disease, its causes and symptoms, and www.nhlbi.nih.gov has its own overview of peripheral artery disease. MedlinePlus also keeps a reference entry on plethysmography.

A question worth bringing to the clinic

If you are in Mokena or New Lenox Township and a leg symptom keeps returning, ask the clinician what they think is causing it and how they would confirm that before recommending any treatment. A cause that has been confirmed is a better basis for spending money than a guess.
