Peripheral arterial disease (PAD) is a common arterial problem in which narrowed arteries reduce the blood supply to your limbs. Thus the decreased blood supply to the extremity cannot cope up with the demand. This leads to leg pain mainly on walking (Claudication).
Peripheral arterial disease is also a warning sign of reduced blood supply to other organs due to the generalized disease called atherosclerosis which is the deposition of fat, cholesterol, calcium, fibrous tissue in the wall of the arteries. This reduced flow may affect your brain and heart.
PAD may be successfully be treated by giving up smoking, walking and eating a healthy diet.
