PAD is a circulatory condition in which narrowed blood vessels reduce blood flow to the limbs. Though it can happen in any blood vessel, it typically manifests itself in the lower legs.
It is primarily caused by the buildup of fatty plaque in the arteries, which is called atherosclerosis. Due to a lack of education around it, PAD is often left undiagnosed by healthcare professionals, often due to their patients lacking any symptoms.
Most importantly, if left untreated, PAD can result in amputation.
