Peripheral Artery Disease :
Peripheral artery disease is a medical condition in which narrowed arteries decrease blood flow to limbs, mostly to the lower extremities because of a growth of fatty deposits called atherosclerosis. Age is most associated with its problem occurrence amongst older adults. It may occur amongst other smokers, diabetics, individuals with high cholesterol, and those with very high blood pressure. Pain is experienced with decreased blood flow, especially with activities like walking. Symptoms include leg pain or cramping, particularly when walking or exercising, leg numbness or weakness and in its most severe stages can cause sores or wounds on the feet that just won't heal. In extreme cases this can even result in tissue death (gangrene) which might require amputation. peripheral artery disease is mainly treated by improving blood flow and eliminating the complications. Changes in lifestyle such as quitting smoking, managing blood sugar levels, and exercise should be initiated. Medications are prescribed to attain low cholesterol, control or regulate blood pressure, or avoid blood clots. Procedures such as angioplasty or surgery in bypassing obstructed arteries become necessary in more advanced cases.
